Getting ready for track.

[danaldo]

Hi all, just looking for some advice on tyres and wheels.

Firstly at the moment i have two set of wheels, one oem and a set of volks, both in 19". I gather that more people are starting to run 18's, is there a marked improvement in doing so? Only interested for on track performance, not doing that many road miles at the moment.

Is another benefit of more types of track tyre available? Such as dunlops? Just really wandering what people are running and thinking of changing a set of 19's to 18's.

Secondly and more importantly I also need to get a new set of cups, especially rears, and was wandering where the best places to look for them are? Again also need to source some new rs29's and was wandering the best place to look for them is?

Many thanks.

I don't know about 18'' Vs 19'' wheels, IMO the car was designed for 19's so just as well keep using them, but then I'm not exactly chasing tenth's on track!

As for the RS29's have a chat with Simpsons Motorsport, superb company who are very professional and will do a competitive price for you!

As for tyres the Cups I don't think are being made in 18'' any more, however for track tyres you have lots of choices, Michelin PS Cup, Toyo R888, Dunlop DZ03, Kuhmo V70....

If tracking on Cups, 19s are easier to get hold of than 18s but if considering other tyres, 18s are the way to go as they will be marginally cheaper, lighter etc and also gives you the option to run slicks later. I run 18"/ Cups for track, and tbh not sure what can top them for performance. Yet to try Dunlop DZ03s but being more expensive than Cups... Not worth changing.

Ref: RS29s are you standard or BBK? Most places will source them. Thorney is cheap for Fronts - AP fitment.

I may be getting rid of a set of New 19" Cups v.soon.

18inch Cups are heavier than 19 inch !! (more rubber)

So I remember you saying, but ment the wheels as standard ;)

I've never weighed the 18 inch BMW rims but I'd put money on them with 18" cups heavier than CSL rims with 19" cups

but anyway, 18s as KK says give you more tyre choice if you are in a budget
