Coil overs on all 4 corners... dropped about 1.5 inches. After I finish my motor and engine bay project, I will drop it another half inch. Coil overs are great!
The only thing I did was flip the quad shocks...that takes about 15min to do, if you have air tools. I have no rubbing issues, but my wheels are only 17x8 Mach1 wheels. The springs are stock, but I plan on installing a set of FRPP "B" springs soon.
