Corvette Suspension Dimensions Needed

[geoffreyj318]

Where can I find information for mounting Corvette C4 or C5 suspension, on a custom frame?

[Mike Hall]

I have exhausted the net looking for such dimensions without any luck at all. Maybe someone will share these specs with us but I would not count on it.

Download Performance Trends Suspension Analyzer. They have both front and back specs and more for whatever info you want on the C5 in there example files. You can also change around the specs and animate to see how it will change Camber, Scrub, etc.

I got the dimensions for the C4 from my local collision center. I still had to do some math to get the wheel base however because it wasn't included. I was able to figure it out from them and ad the 12in. approximate for a 1st gen fbody. If you get the frame mounting points right the wheelbase follows naturally.

hey Jim,
I'd love that C4 info as well, can you post them or email them?

thanks

[Mike Hall]

Thanks for that info Novanutcase. I think I can draw up a subframe with the info given my that program.

Good Luck and let me know if you figure out how it works. I haven't been able to really make it do what I want it to but what I have done has been eye opening!

[geoffreyj318]

Thanks for the info. I downloaded the software, and got the C5 dimensions. How close are C4 dimensions to C5 dimensions?

If you have the rear C4 mounting dimensions, I would love to have them.

Thanks,

Do you need the batwing mounting dimensions? It's 95cm from bushing center to bushing center.

[Tiger]

Thanx nova, i'll download when I have time.

[Samckitt]

The location of the forward "dog bone" arms in relation to the batwing is what I would like to have.
Thanks

Why stick with the stock position, might as well customize it to give a virual swing arm to suit your application, makes centering the wheel in the wheel well easier also if you make them adjustable.

I'd be interested in dimensions for the C4 rack and pinion unit if anyone has that.
Inner tie rod pivot point spread and mount dimensions off centerline would be great.

C4 rack and pinion has a 26" center on the inner tie-rod pivots. It mounts with a clamp style on the pass. side and a bolt through a bushing on the driver's side... I can measure it up tomorrow.

You can see some pics of how it mounts at this link.

I'd like to know the rotor face to rotor face width of the '86-88 C4 rear and the '88-92 rear end.

I've got one of each, one for my '70 Challenger and one for my '71 Barracuda. Was wondering how much I may have to narrow (I think the earlier one is 1.5" narrower) since e-body rear ends are 61 5/8" drum to drum.

[Porterbuilt]

The 88-96 is 63.5" hub to hub with the rotors in place... this is with the half-shafts paralell to the ground.
