**EDIT*** - This was a FAIL. The Lakewood bars will NOT work with these drop springs. This may be a combo of how my pinion angle/pads were welded to the 9" as well. Even with the shim kit (talked to the tech guy this morning) - it won't work.


So....the Vette Brake spring did fail which I believe was related to the center bonded on pads going away and allowing it to wiggle - but I'll be updating this and the youtube video I made.*******


The vette brakes and products fiberglass springs had an odd failure. They are older and the mounting pads dry rotted away allowing them to shift and snap the center pin. They are out of business now. I thought about the ride tech composite springs but $800 was out of the budget.

I swapped in some summit 2” drops.

They are about 3/8” or so lower that it was.

Also I put on some Lakewood traction bars.

Not happy with how they sit.

Made a video.

I’m glad I didn’t sell it to anyone as the fuel pump, springs, and now master cylinder have all gone out in a couple of months.

Here it as in 1986 with the old school traction bars. Of course it sat like a 4x4 truck back then with 275/60/15 outback with air shocks.

I'm familiar with the VBP suspension.

I used their rear springs on my 70 in 1996 and in 1998 on my 67. Haven't had any failures yet, even though I have heard stories of them breaking.

Actually, I put their complete front transverse system on my 70 Camaro including their sway bars, tie rods/ends, idler and ball joints (Moog) in 1996. It handles great even if it is pretty stiff.

Yep. It is generally good stuff. Time just got to the softer parts.

I was sponsored by them for years and did c3 install videos. I did a magazine article on a 76 trans am with the front transverse.

But the bushings do go bad. Not their fault, they just go away with time like we do.
