I was wondering what size the brakes are and what the smallest size rim would fit. If you were to seriously think about this car running in ASP for autocrossing this is going to be a performance advantage to get something wider on it.


Thanks

15" is the smallest wheel you can fit.

The front brake calipher will just fit inside a 15" wheel, but any stick-on wheel weights must be fitted away from the center of the wheel, as they will be a bit too thick and 'catch' on the calipher.

Bye, Arno.

thanks, so then you could run a 15X7 or 7.5 or 8 with a stiff enough spring/strut combo and have more choices for autocross tires if you were to put into ASP.

would you be doing this for
a) mechanical advantage or
b) less rotational mass.

If its the former (instead of getting a new final drive), you only need to worry about the rears.. Leave the fronts alone. not sure about tire/ wheel fitments, but its something to consider.

Basically all of the above. The main consideration will probably be finding R-compound tires that fit (particularly in the front), and then choose wheel size accordingly. I guess running a smaller tire could also help the clearing prolems, maybe allowing to run wider tires? Reducing the overall diameter of the tire also lowers the car, reducing weight transfer, without any negative influence on suspension geometry.

You could got for the 16x8 and 15x7 combo that I have. Because of this, I get access to alot better tyres. Right now these are Yoko 038 SS (super soft compound) tyres:

What size tires are you running? Or what is the widest you think you could fit with those wheel sizes and your suspension setup?

rear 225/45/16 front 195/50/15. could probably fit 205 to the front but then you open yourself up to flexing which creates intability in long corners. right now, the thing handles on rails.
