on stock suspension. Will this work with no Modifications, Spacers or fender rolling?
I thinking about Apex ARC 8 with RE-11's for autocross. 5 lbs/rim lighter than stock! 
It will just be casual AX, so I want to be conservative, not create any rubbing issues, but get as much rubber down as I can. |
You will clear with no problems at autocross or daily driving. However, if you install camber washers you will need 5mm spacers on the front to clear the struts.
I have BFG Rivals and ARC8, same specs that you mentioned.
