Tire Size for My Coupe Quattro - Help!

[mlp]

Pedro -

You might want to think about going the other way around if its performance
& not Looks you are after.

I.e., you could take a page for the June 95, European Car, RSR Exocet
missile, MTM Roland Mayer approach - 265/35ZR 17's ties on 10J x 17" wheels
on the front and 235/45ZR17's on 8.5J x 17" on the back.  According to the
author "...It will eat a Ferrari 512TR for breakfast up to 140
mph-plus,...."  ????

Reportedly either the end of, or greatly reduced under steer.
May require "some" sheet metal work.
