i had the ebiach pro kit installed back in feb with the headers, i loved them but my mechanic just did coil overs on another stang, so he was gettin rid of the sportline front springs so he said for 50 buks i can have them. so i had him throw them on and it looks great, very lil space between the wheel and the fender, but i still have the ebiach pro kit in the rear, the dif is 1.5 on the pro kit and 1.8 on the sporline kit, so i was just wondering if for some reason that this was gonna be a problem at all. thnx bobbyoooo
