Suspension Combo - input wanted.

[TPI Monte SS]

I've been playing with G-bodies for about 7 years. I'm no expert, but I've put enough street miles on them to have learned a few things.

Tubular rear control arms from UMI – polyeurathane bushings.

The lowers will be fine. I recommend Edelbrock adjustable uppers though, with the spherical bushing on the frame side. I have this setup on my '88 and like it a lot.

Polyeurathane bushing kit for front suspension and steering.

Too stiff and squeaky! Stay with stock rubber, IMO.

Addco sway bars – 1 3/8” rear and 1” front.

They might be OK, but a cheaper and better choice are the stock F-41 bars.

Bilstein shocks.

Factory rubber body bushings. This is one of those ride/streetability compromises.

No complaints on either of those. I have them and really like them a lot!

Suspension techniques 1” drop coil springs.

What's the rate on them? I have Eibachs in my '88 and am happy with them.

Rear seat braces(helps tighten body for T-top cars)
Front frame braces and connecting brace.(ties front frame together)

Both are good additions, and you can also add bracing from the core support to the inner fenders.

Simmons racing wheels with 245/40/17 fronts and 285/40/17 rear.

Sounds good. I have 245/45 17s on my '88 on all 4 corners. The ability to rotate tires is a plus.

Good luck with your project!
