The only thing is that at 180 degree of steering lock and when going onto an angle such as going up a parking ramp the front tyres rub slightly on the vents that are in the plastic at the front of the wheel arch. I don't think this is due to the width but more the increased height of the 285/35r20.

The Porsche Cup2 that came originally on the GT2RS is a 265/35r20 but is really wide with an 11.4" tread width vs the 285/35r20 I have which is 10.1". I might try and find some of those to fit at the start of next summer over here to see how they fit on the car.
Thanks for the quick reply! Based on what you said here and in the other thread there is plenty of room both inside and outside. I am wondering why 10" front is not the standard M6 fitment for aftermarket wheels? That would allow a wider range of tire options from stock 265 up to 285.

I really like the style (and price) of HRE FF15, but they don't come in a perfect size for M6. What I want to do is run 20x10 ET40 with a 10mm spacer front and 20x10.5 ET26 with a 10mm spacer rear. Based on your experiments and my math that should clear both inside and outside with enough margin. What do you think?
