I believe they are HX's. 14 inch. we are also looking at some 15 inch SI rims. I'm looking at some sumitomos that got good reviews from green seal.
why would a stock exhaust be more FE?
I was also wondering if anyone has put a WAI on a D15B8, and how it responds? or even how they ran the ducting.
PS:is it safe to run full synthetic in the engine and/or transmission
