Lowering a '91 ZR1
What advantages are there to "lowering" a ZR1? Can it be done with the selective ride system? Should it be done? How can it be done? Just an inch or so.
With my '80, lowering the rear is easy with longer bolts, but the front coil springs are more problematic. I was wondering what it would take to lower my '91 ZR1? |

Re: Lowering a '91 ZR1
lowering the rear is just like your 80 (longer bolts . the front howevert is more involved ,you must remove the front spring which is a pain and put on a different bumper . you can find the pieces in any of the corvettte catalogs .or switch to coilovers . to me the car is low enough , my 92 has coliovers which makes it 2 in lower and it scrapes on everything ,even ants jk

Mine is NOT lowered, and speed bumps anywhere are a certain drag! For the street, I wouldn't want to go lower. If I were tracking it...That might be a consideration...might be. With regard to racing on a road course, I wonder what Jeffvette would have to say 'bout lowering the Z? (If anyone would have an expert opinion, he would, I recon.) P.

Re: Lowering a '91 ZR1
Another vote for not lowering it. The car is low enough and the speedbumps in my neighborhood are a PITA no matter what the angle of attack. Especially if you are running a B&B fartcan resonator on the underside in the midline. I see zero benefit beyond maybe autocross and only with the additional modification to coilovers and other suspension mods. other than that its a personal preference. GM did a very good job in the configuration the car is already, JMO your mileage may vary.

Re: Lowering a '91 ZR1
I think the main advantage of lowering the car is the visual improvement. Dialing the rear down a little helps a lot in the looks department.

Re: Lowering a '91 ZR1
Any comment on what it might do for traction at the track?
In that same vein, anybody have a preference on FX3 settings for the drag strip? |

Re: Lowering a '91 ZR1
Springs don't work that way. The spring is pushing the car up with the same force as before, which is exactly the force required to counteract gravity. In order to provide that force, it will be as tensed as before. You are simply changing the mounting point, which changes the ride height.
