I am looking for some advice and information. About 9-10 years ago I had a Corvette shop redo the front suspension because the front leaf spring was cracked. After the new spring the front sat and still sits low, but at the time I figured it was all I could do since finding a spring seemed difficult. Where I live now they installed speed bumps on one of the side streets I need to use to get out of my development and I know the Corvette will not clear them without dragging the front spoiler. It has been bothering me lately that the front sits too low so I began investigating, but hit a roadblock. The Corvette shop does not exist anymore so getting information from them is not possible. I have often thought the wrong spring was put in. On the top of the spring, I noticed the markings 016-2 and k-300. Underneath the spring I noticed 016-2, 88-96, k-300. I cannot find any information on who made the spring, but my best guess this is a 300 lb/in spring. I have a 1990 with adjustable ride select suspension and the best I have been able to find out is that it should be a 350 lb/in spring (FE-1). Am I right in assuming this is the wrong spring which is causing the low front end? I'm not sure who made the spring, but I remember giving the shop Van Steel, Vette Brakes and Parts, Corvette Central, Zip Corvette and maybe a few other catalogs because they said they couldn't find the part. I'm not sure where they bought the spring. Any help or advice would be appreciated.

 

Not knowing what they sold you it's hard to say why it is low. A aftermarket sport spring could have a higher rate with a lower arc lowering front end. The original FHA springs are common in used parts channels and normally inexpensive. Vetted Brakes closed years ago, someone did buy the spring manufacturing equipment, although I can't remember who. Aftermarket springs can get pricey. I would find a FHA spring and see what happens.

 

Thank you for the reply. I recently found a video on YouTube where the guy switched to an aftermarket then switched to a used original and showed the difference in the bow. I was wondering if a different aftermarket would be a better choice, but it looks like finding a used one in good condition is the best option. Thanks.

 

That is really a budget thing. Aftermarket front spring will be several hundred dollars. A used spring with a FHA code, the FE1 base spring from 88-91 coupe, should be closer to 100 dollars. You could look for a label on the spring that is there, to identify it. If you're happy with the stock spring you maybe able to recoup your costs selling the spring that was removed.

 

You might get someone to trade you on C4 FB page there are always people asking how to lower.
