Title: C3 chassis
Post by: bfit on April 07, 2011, 01:20:13 PM

Hello All
Does any one have any experience with  this conversion
I am looking at fitting C4 suspension under my C3.

I am also looking for a good set of drawings  of a C4  chassis
showing at all three elevation

I hope to get  some positive input

72VET has recently done that conversion. I'm sure he'll chime in when he reads your post.

Dave Kelly up here on the Gold Coast has done this too.  I'm sure he would be a wealth of info.  You can contact him here. (http://www.qldcorvetteclub.com.au/club/questions.htm)

Hi Bfit

Yep, purchased an aftermarket set up from VB&P for the front-end http://www.vbandp.com/C2-C3-Corvettes/Suspension-Products/Systems/Transverse-Composite-Monospring-Kit-1963-82.html  at the time the price was a lot less than what their asking now, purchased the upper tubular arms as well. Installation was simple, bolt off and on.

The positives -
Ride height is adjustable along with the spring rate.

Negatives –
You lose a bit of ground clearance with this set up.
Shock length is shortened due to the design of the new lower arms (which they don’t mention:grr:) As there’s no need for the spring saddle on the lower arm the plate for the shock mount is flush with the arms so you lose about 1 ½ inches of travel. I haven’t resolved that problem yet. :bang:

Noticed that wabco40 also has the same set up on his car.

I have the same set up as 72vet. I purchased it about 6 years ago and even back then it was a proven product. However I am still yet to drive the car with this set up.

If I had found I had a rusted or damaged chassis when I started the rebuild then I would have purchased a Street Shop Inc C3 chassis.
I have spoken to their rep and seen the quality of their chassis. They available from bare frame to complete rollers with your choice of engine/tranny mounts.
There not cheap, the prices several years ago where 9 to 15 grand. With the dollar the way it is at the moment the prices are not to bad.

thank you  
Looking forward to some more postings
wabco40   those photos look extraordinarily tidy
I have been trying to contact Streetshop  my email  missed them on a phone call today will try earlier tomorrow .
I do like the look of there chassis .

wabco40
The mod to your chassis looks excellent


I would like to  go with a stronger chassis than the standard vette  as I think with a reasonable amount of Hp  the chassis will flex far to much  For  a glass bodied car.

I don't think you would have to worry about the original chassis flexing even with a large HP engine.

The advantage of the Street Shop chassis is that it is made to be fitted with later suspension components where an original chassis has to be fitted with an aftermarket suspension.
The quality of the welds on an original chassis are a bit average as well. Before I had my chassis blasted and powder coated I grinded and re-welded most of them. The welds on the rear kick-up and brace where extremely poor.

I haven't dealt with Street Shop,  and it's odd that they haven't responded to your emails.  Perhaps you could call one of their approved installers to find out what's going on:

Would anyone have a  69/74  chassis  straight in average condition
Even a rusted one would do  that's not bent
I want one to mock up  my suspension.
If you have one for sale contact me
