I want to lower my ZR any advice or suggestions.
I really want to lower my 91 ZR1. To those who have lowered cars any advice or suggestions would be appreciated. For now I will be staying with either the cars original saw blades or the set of chrome A molds. But I really love the look of lowered C4's in general.

My opinion is to stick with the stock painted saw blades. When was the last time you saw them on a '91 or '92 Corvette? They look great in my opinion. I have never been a fan of chrome A-molds. ...But that is just me. It is ironic that all my cars have A-molds, but that is indicative of their year.

When I lowered my car I almost went with coil overs but found the VS&P made an adjustable front spring. Not sure that’s the name or if they still sell the spring. The springs got 2 threaded nutserts in the ends of the spring and an adjuster that comes in contact with the spring. At the time the spring and longer rear bolts was less than $600 I really like the OEM 91 wheels,it took me more than 4 years to put together an NOS set. Even though I’ve got a nice set of aftermarket wheels on the car I’ll put the stock wheels on it he car from time to time.

be careful that you don't lower too much as you can bottom out the shocks which is no bueno. ZR-1 look GREAT slammed and the coil overs with the right spring rates and shocks are the way to go if you can handle the initial tab and buy in. You get full adjustment capability, and with the demps new shock setup, improved and much lighter shocks that can be serviced.
Unfortunately the bilesteins which are a good shock, are hard to come by and expensive. And to me the fx3 which cool in its time, isn't nearly as good as improved shocks.
coil overs work great on the track and street if setup right and eliminate a bit of the skiddish ness in the rear in bumpy corners. I also went with the bansky rods to replace the dog bones which freed up travel and helped the car plant HP and track better with sperical rod ends rather than bushings. I was worried about "harsh ride" but that turned out to not be a problem. Also look at the DRM camber brackets which bolt on with either setup.

I love the looks of lowered Z's but have resisted lowering my 90 after trying to get a brother's lowered Z on my 4 post lift and the exhaust would not clear. We had to create this long approach out of 2x6 lumber just to get the car on my lift. I store my ZR-1 on my lift with another car underneath and that would be too labor intensive every time I wanted to drive it. Just a word of caution if you have a 4 post lift.

On my 94, I used the Vette Brakes & Products adjustable front spring, like Jeff. On the rear, I used a longer pair of bolts.

Ya gots ta work wit what’s ya got! In all the time I’ve had my Z it has never sat outside overnight. When I brought this bike home a few months ago I said to myself,hope this works or this brand new bike is going to sit outside until I figure sumptin out. It’s been a couple months since I haven’t drivin the car since and I do miss it.

I put QA1 coilovers from Van Steel on my 94. Pretty easy install and my Z rides better now than ever before👍🏻 Handles amazingly as well!

Some words of warning about lowering your Z:
You become a bottom feeder. I think it sucks down better at high speeds,
but peaked driveways and speed bumps become a hazard. I've flattened
my transmission drain plugs and bullet cats. Tail pipes and front air dam can hit.
Careful opening the door at curbside.
It can change your alignment, tire wear and handling. But... it looks COOL!

Thanks for all the replies. The down sides I pretty much expected. Has anyone just lowered the rear a couple inches and left the front alone. Was wondering what that would do to the cars balance?
