Bimmerworld is releasing their TA16 forged wheel in an 11x18 ET36. They recommend a 41mm spacer when running their full GTMore suspension on a standard M4 chassis. Not sure what the spacer requirements are with the GTS suspension.

You're right. I confused the M4 GT4 with the M2 CSR and the GTMore

Has anyone run 285/35/18 (specifically Hankook RS4) on a 10.5 front? Will be running 10.5 et22 (effective) in front. According to TireRack the OD is only 25.7 which is usually shorter than a nominal/regular 285/35/18.

I haven't run that specifically but wouldn't anticipate it is a problem, at most might need a small spacer in front depending on front suspension setup
