Wheel weights

[Evilchap]

Something that is a constant frustration to us is wheel weights.

We have just had a wheel in, brand new, Team Dynamics Pro Race 1.

15x7 ET35. It's meant to be 6.1kg according to the website, or close to this:

http://www.teamdynamicsracing.com/pr...e1hpsilver.htm

It's actually 7.8kg.

When we advertise a Slipstream in the same size at 5.9kg it's being on the safe side (my purple ones were 5.8kg each for example), but make it look like there's not much advantage to it, whereas actually there is.

Very frustrating! So many other places advertise wheels as being light, and get their weights wrong, but on the internet and on paper they look light, despite the fact they're not.

Did you take the tyre off

That actually says FROM 6.1kg

[Marsden]

It's a 15x7 and I would have thought one of there smallest sizes so that "from" should be somewhere near. Thats ridiculous how heavy it is for such a small wheel.

Ain't they a halfrauds special anyway?

[davesx]

That actually says FROM 6.1kg

And 'At highest offset' which is +48, so the +35 will weigh heavier.

[FIGJAM]

Pro race 2 is used in the Mx5 race series, so a bit crap using a heavy wheel on a car that respons well to weight reduction, even more so if its unsprung

[Evilchap]

That's the point, they're a well respected manufacturer thought of as a good brand, and by no means unique in doing this, it just makes me sad.

That's a brand new out of the box wheel I weighed. Yes it says from, but it doesn't get much lighter in 15", there aren't any narrower ones, perhaps slightly higher offset, but not 1.5kg worth of higher offset

Sure it's a Pro Race 1? Wheelweights.net (who are usually pretty accurate - not manufacturers data, actual data) list it as being just under 6.1 (allowing for conversion errors)

[Mark]

Its like that with everything you see advertised, you always see the best thing advertised be it weight, performance, price etc. Its clever marketing and gets people interested

Look at car adverts, they use a top of the range sporty model and then say 'From £7995' but in the small print you get 'model featured has shitloads of options and will actually cost you £15k'

I am sure the wheels in one form or another do weight that otherwise it would break the trade descriptions act its just they are not going to list every configuration and its weight

[Evilchap]

And 'At highest offset' which is +48, so the +35 will weigh heavier.

13mm cylinder, 140mm diameter with 73.1 hole bored in the middle and 5 other holes in there 13mm diameter.

Using rough calculations and the relative mass of steel not aluminium alloy to err on the side of caution, if that thickness were STEEL it would weigh 0.85kg, no including the extra chamfers for the spigot ring seat, as working that out at the time of the morning is too hard

So with the most generous will in the world, that wheel in ET48 is 6.95kg

I am sure, I have a set of 4 here brand new in the box (well probably quite old as they're out of production, but never used and shiny)

I am going to have keyrings made of our range, and list them all from 200g

It might be a Pro Race 1.2.

Ain't they a halfrauds special anyway?

Nope - they are the wheel used by the BTCC

I had some 15" pro-race 2's on my 106 GTi. They were pretty light when compared to the alternatives and abour the same iirc as the standard 14" alloys.

[Evilchap]

It is a 1. We got it for somebody due to the spoke design being good for brake clearance.

We're not total numpties here, despite what certain people may think

I just realised my Slipstream I compared it against was 4-stud, so heavier as a result

It's not a heavy wheel per se, just not as light as advertised. This is probably what all the Ma5da people are switching to Rotas now they're allowed in, saving 1kg a wheel is probably quite a help

Sure?

The 1 I thought had been discontinued for some time now. At least it had 3 or 4 years ago when I was looking at them.

Si,

Wheelweights.net is not accurate, some are are wheel manufacturers data, some arnt.

Its definatly a pro-race 1

Its brand new in a box,

[Rarerims.co.uk]

Its very easy to tell a 1 to a 1.2

a 1.2 has bloody great writing around the edge of the wheel

[Phill]

I like the ProRace 1's as they don't have the chavy 'Team Dynamics' cast into the rim.

Haha! That'd do it!! I forgot about that

[piman2k]

I had 1's on my 405, as Julian says the 1.2 has Team Dynamics in the actual metal of the wheel lip. The 1 does not.
