I think the subject pretty much says it all but I am slightly confused as to what wheels I'm allowed to use and stay in stock class for SCCA. Right now my WRX has the default 16"x6.5" wheels. However in my manual it looks like there was a 17"x7" dealer option wheel, the BBS RGR wheels I assume. On the very last page of the manual, the "Gas Station Reference," is where this is located.
My car obviously did not come with the 17"x7" wheels so would I still be allowed to purchase any 17"x7" wheel and stay in stock or do I have to stick with 16"x6.5" since that's what my car came with?
I'd like to do the summer/winter wheel/tire thing but want to make sure whatever wheels I get won't be a waste of money and wind up knocking me into a higher SCCA class where I will surely get spanked.
Thank you for any help.
