Hey guys I got a c4 in good shape I'm restoring! But it sits a little to hi for my likings! Anybody got a recommendation for a lowering pkg?

Id tell you its low enough however coil overs is a good option and most of the major corvette aftermarket house have a rear spring lower kit available

What about the front?

USAZR1

If you do a search in the C4 Performance forum, you will find all kinds of info about lowering your 91. Lots of photos of lowered rides,too.

Ty! I've been browsing a little! Basically I've found that running longer
spring bolts should do the trick!
I just want to do it right the first time!

The front suspension requires more labor to lower an inch. You use the "wedge". The rear is just longer bolts.

ZR-71

Mine's only lowered in the rear. I don't' want the tires too close to the body

I'm just starting to get into this puppy! I was not sure what pkg's are available for these C4's
Some Machines have adjustable ride height coil overs on all 4corners! I was hoping this C4 might have a pkg avail.

I am running DRM coil overs on all four corners. These allow you to remove the front and rear composite springs and adjust height with the turn of an adjusting wrench up or down.

Ty That's exactly what I was looking for! How you didn't tell me sooner?
What's the FX3 pkg?

Goldcylon

FX3 was standard equipment on all ZR-1s. It is a suspension control system that adjusts according to speed of the car and the input settings of the driver in the car by selecting one of three modes on a dial in front of the center console (Tour/Sport/Performance) which sets mechanical actuators that are on top of all 4 Bilstein shocks to a selected set point by turning a mechanical gear that adjusts on top of the shocks. It was 80's tech used on Ferrari's at the time.

Basically for a softer ride you would select "Tour" and for racing and hard cornering "Performance" setting was used which stiffened the ride. Back in the day it was pretty high end tech
