[QUOTE="Manny@Dasilva, post: 8809, member: 78"] How to lower a C4: C4 Corvette lowering procedure. Time to complete: Front: 3-4 hrs, Rear: 30 minutes Tools Required: Lug wrench 2+ ton floor jack 2+ ton jack stands Various 1"x4", 2"x4" and 4"x4" wood scraps Ball joint puller Rags Pointy nose pliers Metric socket set Weather-strip cement Utility knife or Dremel (for removing spring pivots) Tape Front Procedure: The car must be lifted in stages to reach this height. If your jack isn't low profile enough, try driving your Corvette's front tires onto some 2x6s first. The Z51 spring is stiffer and therefore less curved than the base spring. Base model vettes must be jacked higher than shown in the photo.
