yes i had a + reading at first then cut everything out lower the car in the back with the front hangers and went - and whooooooooa this thing is night and day....like i said at first i could take the car down the road and leave it would burn the tire a good 20' and now nothing else but the angle and lower and i try to leave and the car lefts and bogg and when i got home i checked the slicks wrincles all around both and never had that even at the track...now it jumps just like a frog so i do think i will have some better 60' and et once i get the new found bogg out of it... it woyuld 60' i the 1.66 range with ss springs
