I have a set of ENKEI and after removing trim and rolling fenders the tires still rub slightly.
I feel like goning back to stock or selecting different tire size. Car has been lowered about 1/2".
Any suggestions?

 

yup, Wheels & Tires section... https://www.s2ki.com/s2000/forum/56-...the-tire-rack/

 

Thanks the link has some very useful info.
Do you know offset of the rpf1's?

 

lol, that's for you to tell us man. Offset should be stamped on the backside of the wheel.
