I know very little about suspension systems. Long story short, I am going to put an Iron Block LQ4 in the firebird so it's going to be slightly heavier than the LS1. I want to know a good front and rear suspension setup that will allow me to both hook up and handle. I don't want to lower the car more than half an inch, if even that however.

What kind of Front / Rear Springs should I go for? Are the stock LS1 springs any decent or should I replace them?

Front/Rear Springs with KYB AGX Shocks?

What about the front/rear sway bars and LCA's?

 

stock springs on upgraded shocks.

Koni SA would be ideal, but the AGX might be a good budget choice.

since the front will be lower with the added weight, i would pull the rear spring isolator to level it out.


sway bars made a HUGE improvement in how my car handled. much flatter in the curves.

 

Ae you starting out with V6 Springs or V8 Springs ?
Because the V6 front springs are softer the rears are the same V8 or V6.

 

It's a V6. Yea, I know the front setup on the V6 is weaker than the LS1 setup.
