I already rolled the rear fenders. May be even a touch too much as I think I might need a 10mm spacer in back now for the wheel to look completely flush.
I should have stopped here...
But I pulled it just a tad more. Even though the above looks evil the notion of a rub at 100+ miles per hour didn't sit well with me.
And this just for kicks. AceInHole is running 285s on all four corners! The fronts specifically are 285/30/R18 on 18x10 +20 motegi wheels. I seriously thought that I was pushing the boundries of stock rolled and pulled front steel fenders when I ordered my 17x9 wheels for 255 tires for the front of my car almost two years ago. When I can afford serious brakes that require 18" wheels I will be upgrading to this size tire at some distant point in the future.
I still think that greater than 285 is possible with stock roll/pulled fenders in the rear though. Once the ohlins are in I'll measure the inside clearance to the coilover and let you all know exactly how much clearance is left.
