My Track Day…

I thought would post up my thoughts / experiences for those who have never done a track day but are considering it and could use some insight into what goes on… if your not interested or get bored easily please move on…

Well for some time I have wanted to put the 200sx on to the track but have been genuinely concerned about doing so for the fear of damaging the car / associated risks and whatever other excuses I could think of…

Over the past 12 months I have gradually got the car to how I want it in terms of handling / brakes and power and in my opinion is now a superb fast road car but I was eager to find the cars limits and this is simply not possible with the associated risks on todays roads… I felt my driving ability in the 200sx had improved substancially from watching Steve (SteA) and picking his brain on driving techniques and applying them in practice on cold dark nights blatting over deserted roads time and time again… sometimes with me in pursuit of Steve sometimes on my own pushing the car as hard as I dare…

So the time had come… I decided to book Donnington Park via Trakzone as an early Birthday present to myself and after some advice from a few trackday regulars that Donnington would be ideal for a trackday newbie.

I booked a full day for 4th May so now it was game on to get the car ready for the day… I was somewhat anal with my preparation but then I always do everything to the best of my ability. It’s just in my nature…

First thing was to sort the annoying vibration at the front out which finally resulted in DCMS coming to the rescue and dealing with all but a small amount which was down to the brakes… brand new disks and pads (larger uprated fronts) were installed so they had time to bed in before the day… all fluids changed… new 17inch alloys with semi slick yokohama A048-R tyres put on the car… full alignment done (DCMS) and the car was good to go ready for the day…

Night before Track Day

Load the car up with some basic tools, fill up with Shell V power as well as the loaned 40L jerry cans (Steve), take loaned brake pads as spares (Steve and DCMS) and final check over on the car…

Track Day – May 4th…

Early start as had to be at Donnington Park for 7am to check over car, sign in and wait for briefing… so up at 5am… brief stop at fuel station on way up to top up and then pull into Donnington Park which was an exciting experience to be waved in my the security guy and pointed to the pits… drove round to the pits and parked up out of the way then started to unload everything out of the car and check tyre pressures.

Then it was time to sign in and get to the briefing… very straight forward exercise and mainly about speeds with regards to flags, overtaking on straights and left hand side only and how the sessions would work. Three sessions per hour… novice , intermidiate and advanced… guess what session I was in…

So now the nerves are kicking in as once the briefing was over it was time to get in the queue ready to go on to the track… helmet on (serious lack of headroom in 200 with this on, seatbelt on, CG lock engaged (keeps belt locked as works well), check mirrors and slowly drive through pit garage and into the queue like so:

An initial wait for the guy to wave us through and we are off… nice and slowly with Steves warnings ringing in my head about warming tyres up and taking it easy and getting used to the track… so I firstly started to warm the tyres up and concentrate on the lines / braking points…

What I couldn’t get over was the width of the track… so much room and I actually felt safer on the track than I did on the road…

First session was over quickly but I was pleased with my progress and happy that the car was well suited to the track…cool down lap was done on final chequered flag and then pulled into the pits (by this time we had managed to get a garage to use for the day)

http://i5.photobucket.com/albums/y156/Scott_Davis/DSCN1031Medium.jpg

I left handbrake off and engine running with bonnet up to cool down for a few mins before switching off… I then quickly checked tyre pressures (these raise due to heat) to find they had gone up to 35psi (should be 31psi) so quickly reduced them whilst tyres still warm…

By the time had done all this and chilled out for a few mins it was time to go again… this time I wanted to get some speed up and knew all I needed to do was adjust my braking points in relation to entry speeds….

A quick warm up lap to get the tyres sticky and I’m foot flat to the floor down the main straight past the pits…. Keeping a very tight left and braking hard from 115mph-ish on the blue section into redgate in 3rd gear around 65-70mph turning in as late as possible… then back on gas once corner opens up and accelerating hard all the way round through hollywood and into craner curves… into craner curves just over 100mph and still in 3rd gear and a slight tap on the brakes before corner of craner to stop car from going wide… then back on accelerator towards old hair pin coming right over on to the left hand rumble strip and turning in late for maximum exit speed at around 60-70mph… foot flat to floor round starkeys bridge / schwantz holding a tight line (still in 3rd) then hard on the brakes into macleans keeping left for late entry… going through in 3rd gear around 70mph then back on accelerator towards Coppice braking hard just before the top of the hill again holding a late line in 3rd / 70mph so can get down maximum power for the run on to the Dunlop Straight where we go through 3rd gear then 4th gear topping out at about 130mph before braking VERY hard on the tight left hand side and dropping down into 3rd then 2nd gear @ 40-50mph using the whole width of the track through Goddards (which I suspect killed my new brakes) and then accelerating hard down the main straight to do it all over again!!

By the end of the second session I was overtaking a lot of people and even lapping a few people as well… during the morning I gradually got faster and faster improving with each lap… I missed my braking point therefore the line on a couple of corners due to too much late breaking and got on the power a tad too early which resulted in the back end coming a little loose but nothing that worried me… the datsun was doing well!

Lunchtime and a chance for a few pictures, check the car over to find my new brake pads were half worn… by this time I didn’t honestly care… I was having too much fun!

After lunch I was itching to go and joined the queue early so I was near the front… got the car warmed up and concentrated hard… it seemed for ages that I was on my own when I started to lap people… about half way through the session I started coming up behind Westfields, Caterhams and Porsches which didn’t pose any real problem except for the few ignorants that wouldn’t let me through straight away but keeping patient and close to them resulted in them waving me through…

Towards the front I came up behind a Caterham and a Porsche 911 that were being driven very well and were playing with each other so I nipped up behind them and followed them through staying very close for 2-3 laps and then starting to gain on them a little with each lap… came out of Redgate and managed to get past the Porsche safely before craner curves after he waved me through and went after the Caterham… now this was being driven very well indeed and I had to really concentrate… he gained on me through Goddards but by time I was coming into Redgate I was close… towards craner curves and I was gaining on him quickly and right on his tail into the hairpin and followed him all the way staying close into coppice where he gained a little again before catching him on the dunlop straight before Goddards… this went on for a good 4-5 laps before I gradually could see I was pushing him as the Caterham was starting to look a little flustered on some of the corners so I backed off a little and gave him some space for a few seconds before he waved me through with a thumbs up…

Back to the pits and I was buzzing and sweating… could feel the adrenalin pumping and was bouncing round the pit garage… it will stick with me forever that experience and goes down as one of the best bits of driving I have ever done in 14yrs …

Car was checked over once back to the pits to find tyres were red hot, brake pads nearly not existant and car was low on fuel… a good session then… so I choose to do take the last session easy as I was also feeling tired by this time… but very happy!

Car averaged 8mpg on track...

So there you have it… for those who have never done a track day in their own car… DO IT! – even if you only do it once… you need to experience it… you appreciate your cars ability, you get a chance to see what your capable of, you respect others who do it regularly and most importantly its great fun and you have nothing to be scared of!

MANY MANY thanks to the following people for making my track day one of the best experiences in my life:

Steve (SteA)
Gary (Headcase)
Graham @ DCMS
Everyone@ APEX
Andy (Andy_VVC)

And last but certainly not least… My lovely Wife for putting up with my obsession!

Cheers,

Scott

Excellent write up. :thumbs:

Out of interest how did the tyres wear? Would like to do Donington but I'd like to know if it'll completely trash the F1's.

The Semi Slicks held up superb with very little wear at all... :thumbs:

Headcase was using Toyo T1R / T1S and was melting them :nod: ... Andy was using Eagle F1's... its well known these melt as well :nod:

If I HAD to use road tyres on track I'd use Falken FK451 / FK452 :nod:

Shame. I can see it getting quite expensive then unless I put my standard wheels back on.

Thanks for the feedback. :thumbs:

Good report.
Are there areas of your car you want to change now you have used it on the track? suspension or more power?

Now its been used on track I feel it needs more power... I was only running 12psi though all day instead of my normal 15psi :nod:

Chassis and brakes were more than capable :nod:

Yeah, first I had Kumhos on, they were like skates so i changes the fronts to Toyo T1S's, which were quite a bit better but by the end of the day they were showing lots of 'rolled up rubber' on top of the treads, the rears were as OCD said T1R's, which gave great rear traction but ended same as the T1R,s a little melted:) with a little bit of normal road use they were fine again.. they did wear well though so i didnt wreck the tires..

what i will say though is if you want to get some good laptimes at the track (and by that i mean not have to worry about slideing around bends or not having enough braking) dont use cheap tires.......i THINK T1R's will be fine, they certainly were on the back but didnt test the front...if you are on a budget, have releatively good tires (Toyos will do in my opinion) buy a GOOD set of pads.....it was the braking that i found will make or brake a track day...its quite good fun sliding around a bend and powering out with a little spin as long as you are in control...but you will absolutly dump in your undies if your pads start failing when braking from 100+ down to 40-60 mph...The mintex I had (will check which ones they were) had to come off coz they were smouldering:) so put my Mu Street back on and suprisingly these were better, but as they got hot i started to get juddering, although they didnt fade it didnt fill me with confidence:) so again.......as long as you have good braking i think most people can safely enjoy any track day..(telling it as a novice :thumbs: )

i was running 11-12psi and i felt i could have used a bit more. BUT........i wouldnt run more than that unless you are absolutly sure you have the braking power to cope.....OCD had the big brake conversion and he was braking late...quick moderatly funny story to follow... :)

Andy's missus went in the car with OCD after she had been out with the Civic Type R instructor ... the instructor had told her when to brake on the course and there is one particular straight...forget the name but come out of a long bend.. up to about 120ish then brake hard into the chicane...she told me OCD had passed the brake point the instructor had told her and she was saying in her head.....'ok.. brake........brake........errrrr... brake??' and she said she was crapping it because instead of braking HE WAS STILL ACCELERATING!! lol....

Instructor was :ghey: :nod: :D

You mean the section after coppice :nod: on to the dunlop straight towards goodards (chicane) before the pit lane straight :thumbs:

I was braking at the last possible moment on the dunlop straight into goddards :nod: - I missed my braking point once / twice there and went a little wide on goddards :wack:

Thats why my brakes were mullered :wack: :D

Mr OCD
11-05-2007, 09:56
buy a GOOD set of pads.....it was the braking that i found will make or brake a track day...its quite good fun sliding around a bend and powering out with a little spin as long as you are in control...but you will absolutly dump in your undies if your pads start failing when braking from 100+ down to 40-60 mph...The mintex I had (will check which ones they were) had to come off coz they were smouldering:) so put my Mu Street back on and suprisingly these were better, but as they got hot i started to get juddering, although they didnt fade it didnt fill me with confidence:) so again.......as long as you have good braking i think most people can safely enjoy any track day..(telling it as a novice :thumbs: )

i didnt have time to look for sign posts:)

but yeah, thats the one:) hehe... i only started braking late there after 4/5 sessions.....takes balls of steel to brake late there, especially when your brakes are complaining like mine were.. get it wrong and prepare for some front end re-moddeling:)

There were no sign posts... the signs were in my head :nod: :wack:

My brakes were vibrating like a biatch :nod: - Andy's missus mentioned it also... :nod:

There is also a run off section at that point if you get it wrong ;) - Ask me how I know ;)

Mate, this is a great write up but you really have to learn the meaning of the word "opinion". I found my front 1144's very capable on Donny, I didn't experience any brake fade and IIRC, they didn't eat themselves up like your Red Stuff's did.

I'm not implying that they were the best ever. They weren't. But in my opinion they were very capable, if not too dusty and squeaky.

Its my opinion that Mintex 1144's were shit... I drove Headcases car with them on ... and they were shit...he agreed with this... he also cooked the pads after just two sessions... removing them in 10mins showed massive cracks across the pads and the pad falling away from the backing plate...

Still want to stick up for them? ;)

My opinion :p

EBC are also shit... :D

You must drive like a girl ;)

I have just changed tp EBC red stuff ceramic all round on my car front and rear and think these pads rock

Very quick edit there eh Scott, because the above points out that opinions aren't always right.

nice write up! makes me want to track my 200! something i've never planned on doing.. although i get a nasty brake vibration too :( will have to sort that before doing anything i guess!!

must have taken you a good few days to detail the bug splatters off the front of the car? :nod: :p

i did find the Mintex to be rather rubbish....and an opinion can be neither right or wrong.. you can disagree with an opinion but to say its wrong?? :no: anyway.. thats me just being picky. :)

there were probably a number of reasons the mintex failed...but they did fail rather spectacularly :nod: so wont be using them again... :no:

It was an ace day wasn't it! :thumbs:

My standard pads and discs just about held up to the battering i gave them as i became more confident. At the end i had 1mm of front pads left and the rears had hit the wear markers/metal insides...doh!

7 sessions were just enough. By the 6th and 7th i was happily (almost) keeping up with Scott which is no mean feat i can asure you all :D

Car never missed a beat. Ddin't overheat. Didnt lose oil or coolant. Really handled herself well! :cool:

Excellent write up. :thumbs: Looks like alot of effort went into that.

I think you've convinced me to take mine on the track now too.:sxoc: I've only ever been out on the track once and that was as a passenger in one of the old rover tomcat race cars. That was at donnington too as it happens. I loved every minute of that and I can only imagine doing it in your own car would be twice as much fun!
