Default Rear Suspension Mod advice

Ok, my car is a stock 1995 Z28 that was an auto car converted to T56. Car has 170k on it and the rear has the normal bearing/gear growl. I am swapping a 3:42 gear rear end from a newer Z28 that only had 29k on it. Motor is a stock rebuilt 355. I am also considering a cam. Other than that it's going to be it for engine mods. Won't see much track time. Pretty much a nice weather street car.

I have a set of 1.5" lowering springs going in also while I am doing the rear. I believe I need the adjustable panhard bar to re-center the rear for the lowering springs. I also am planning on doing new shocks. While the rear end is out, what else should I do if anything? I don't want to waste money on parts that I don't need.

Since you're lowering it, I'd say lca's and relocation brackets as well.

Lower control arms and relocation brackets. Grab the torque arm from the other car too. I think the manual ta is reinforced and the one from the auto is not. If it was not changed during the swap.

Id go ahead and throw a 255 fuel pump and hot wire kit in. The rear pretty much gota come out to do it. So since u pullin the rear u might as well. That will cover u for future mods.

If (and only if) it will be drag raced, air bags in the rear springs help - 15 lbs on the pass side and 10 on the driver's side.

Thanks for the info guys. I will do some checking into the LCA's, relocation brackets, adjustable panhard bar and the torque arm. If I can find them used would be great. Not in a big hurry, not planning on driving it again until spring.

Not sure on the fuel pump, I may look into that also.

Do I need adjustable LCA's or just the Non-adjustable?

Non adjustables will be fine for control arms. The panhard bar setting varies from car to car when lowering. On my 94 the adjustable was set to the factory bar length and needed no adjustment. My 95 firehawk on the other hand needed a 1/2in. I'd say pick one up to be safe..

Founders performance prices are pretty good. Are their products of decent quality? If so which of the LCA bushing setups are the best to go with?

seem to be made of the same material as the other brands..and there made in the US as well..the only thing I'm runnig from them are the bolt on LCA brackets and they fit perfect no issues..A few buddies of mine are running there LCA,PHbars and seem to be working great.
