I stand by car drives - Rays Ingineering model Versus Championato SS7: on the front axle wheel drives 7x17 ET +50, at the rear axle (Suspension and brake supporta standard) discs worth 9x17 ET +45 with 255х45 tyres. The rear wheels are not hanging and not hurt any elements of the body and suspension. In spring, I will set the braking system of Supra TT, which thickness Torch much more.
To this end, I decided to put another set of discs on the rear axle drive the same size 9x17 with 255 x 40 tyres, and the front drive axle want to put 8 x17 to run the tire 235х45.
To select a set of such discs, I took a Japanese auction. They presented a lot of 8-9x17 discs. I saw many beautiful discs but they have little ET: +30, +33, +35, +36, +38, +40, +42.
Knowing how my disk is - I thought that drive with 9x17 ET +40, and probably will have less contact with the upper edge of the rear wing.
Maybe someone in your drive uses 9 x17 with ET (+42, +40, +38, +36, +35, +33, +30)?
What CD 9x17 rubber with 255 x 40 in which the smallest ET +… will not have contact with the upper edge of the rear wing?
Thank you all for your attention.
