I have a narrow body 993 coupe. I want to run 8.5 X 18 and 10.5 X 18. 245/35 & 285/35. I just received my second set of FM10's that do not fit. I mounted 285's and I have room between the tire and fender for a used credit card. On the inside I have close to 2". 275's are as big as I can go with this offset and rolled fenders. So much for depending on the experts.

I printed the measurement form off of Fikse's web site. When I take the measurements it would be reassuring to have a confirmed target offset that someone may know works.

Thanks,
