Chevell Chassis/Suspension

[SSGN]

I am doing a 66 Chevelle frame off street/strip car. Is there any brackets or braces to do to the frame? Bolt in or weld in? Also what recommendations for springs?? I will be using factory bolt in suspension components for this car also.
Thanks for all opinions.

Alf Wiebe has a great working setup for that body style.

The big block cars had a brace that went from lower suspension mount to the upper.
I'd include it.

Wiebe suspension works great on a drag car but I think it would be too rough and noisey on a nice street car as it has no bushings.

The upper rear cross member that the rear suspension hooks to MUST be reinforced. As the car launches the rearend tries to rotate. It shoves forward on the lower control arms and pulls back on the upper control arms. If not strongly reinforced, the upper cross member will rip away from the frame.

Dick Miller makes everything for your Chevelle.

Is this the brackets that go from the upper control arm mount to the lower? Thanks for the input.

that rules out Alf's and every other manufacturer of aftermarket trailing arms, both adjustable and not.

The go to spring for BB cars was the Moog 5392. I know, because 2 decades ago, I did the work for my car, which was 3900 lbs. and had a 59%/41% front to rear weight bias. Spent days in a Moog catalog, tried many springs and ultimately settled on the 5392 after which I informed all on the chevelle web site. Unfortunately it is no longer available from Moog but a custom spring shop could still make them with the specs...

Moog 5392
17.95".......................Free height
11.50".......................loaded
266 lbs./in..................rate
.61...........................wire diameter
2026.........................total load

and this place was making springs to the above specs back 10-15 years ago...

If the car in question has far less nose weigh on the springs than the 2300 lbs. my car did, you really need to 4 corner scale the car to get the right spring.
