Looks like a leaf-spring
I never understood why some get rid of the leaf in rear and put coils into, and some do the opposite in the front.

I have had a mechanic look quick and said he never saw this before either. Odd.

Hi S,
It appears to be part of a Transverse Composite Mono-spring Front Suspension conversion.
Look at Corvette Central 572264 and you'll see what it consists of.
I'm thinking auto-cross.
Regards,
Alan

It's simple. GM only employed idiots in their design engineering department. It was a condition of employment.

Any good ideas that might have accidentally escaped were caught by the accountants (who actually run the company) and rejected in favour of half price junk.

The assembly line workers, who were paid by the union and not the company, came off strike a few days a year to throw the cars together any old way and were paid a bonus for bad work.

Knowing this, any and all aftermarket components are automatically superior to the orignal stuff. Any shade tree mechanic with a set of harbour freight tools can easily transform a car into an example of automotive excellence simply by flipping through catalogues and randomly choosing the hardware that the factory should have installed in the first place.

Don't forget- the more expensive, the better.

That is actually the VBP transverse composite monospring kit, which is still readily available:

VBP are really good to deal with, you should have no problems getting the replacement parts you need from them.

I wouldn't drive the car anymore until you have the new parts in to avoid any dangerous handling situations or damaging the spring.

I agree, Mike. But in the 60's and 70's only J C Whitney sold the "secret high horsepower" stuff.

Hi,
Anything that replaces that many original parts HAS to be far SUPERIOR!
It looks like it gives a nice flat surface to jack on so the front crossmember doesn't get dented any more than it is!
Regards,
Alan

Thanks I contacted them. Also driving this am in the cool weather I think rear main seal started leaking. While engine was cold I rolled on it some getting on interstate and started smoking bad. After warmed up it was ok. Found oil all over under the car. Fun!

Transverse front leaf spring conversion. Never understood why folks constantly change the OEM design-some improvements are good but generally, not always, big changes. I am not convinced of the rear coil over conversion either or rear aftermarket swaybars with end links like the front bar...

The front mounting bolts for the lower A arms are installed upside down.
The plate should go on top against the frame and the bolts on the bottom against the A arm shaft.
The way that they are installed now is not as strong and not safe.

I don't know if you are being sarcastic or just one of those know it all types. While I am no engineer or race car expert, my C3 Corvette is great fun to drive and handles as well as it needs to driving curved roads at same reasonable and safe speeds for public roads. The car was not meant to be a race car.

I especially like it when anyone, including the self proclaimed experts on this forum and others criticizing the very car the forum is all about. My question is always the same.....what is your claim to fame since you seem to think Chevrolet was made up by a bunch of fools. You must be a very successful and wealthy person since you are smarter than Chevrolet.

Obviously I guess that we all know that this system allows for changing spring rates. Thus the ride changes. And I am sure we all know that this design (front transverse) has been used since 1984 on Corvettes. Maybe NOT being able to be adjusted...as this design shown.

Some people need to live where they live...be who they are in all their GLORY...so the rest of us can realize when we come in contact with 'some' people....we actually have a gauge to compare against. GOOD. BAD or INDIFFERENT. Much like salt and sugar. Both have their uses in the correct applications...and that is also a matter of TASTE. Some people can handle salt in their cereal.....but I prefer sugar myself. So basically I take some comments with a grain of salt....because I now have figured out some 'people'.

It astonishes me that I might have been taken seriously rather than portraying a stereotypical example of our hero Bubba who has had an influence on far too many of our cars.

Hi,
I still think it makes a convenient place to put the jack.
Perhaps the picture could become part of a 'sticky' since the question "where do I jack my Corvette" is frequently asked.
Regards,
Alan

Also, an interesting take on the direction of the bolts to mount the lower a-arm, especially the placement of the 2 anchor nuts.
