I have et street pro's on dark stars for the rear, im really considering front runners right now for that little edge to push my car into the 10.9 range, I need to shave 3 tenths off to do so, and have yet to run the slightly larger shot that i can run, I dont want to rip the interior out of it to hit this number, even though that would be the cheaper option I want it like it goes down the street every day aside from the track wheel tire combo, I don't know who makes a radial front runner or if that's what i need since i run a radial rear I'm guessing so, any other suggestions welcome, but don't tell me to put a converter in it lol its coming i want this on the stock converter
