I got the 8.5 installed that I got out of a 83 police cruiser. Lower control arms, shocks, Canuck Motorsports 1.5" lowering springs. I will say they lowered it quite a bit and these were for the 1979 Caprice not the 1994-1996 Impala SS. I wish they made a 4" plus backspacing with the wheels I got on the back they did not and they are only 3.75 so I am hoping the rear don't squat too much and hit my new 275x60x15 M/T drag radials. The fronts should be here this week they are 15x7 rims with M/T SR's that are 245x60's. Now I just have to get the driveshaft shortened, re-welded, balanced and new U-Joints and should be just about ready for the road again.
