Hey everyone,

I have a suggestion or more of a question, this was brought up by my friend to me. He tells me if I put rear V6 springs on my Z28 that it would help me launch better on take off's. For the reason of the spring tenssion or something like that I couldnt remeber what else he was telling me. He alo told me that he read this off a Camaro mag but not sure which one though.

Any info would be appreciated.

Thanks. Tony.

Chances are that the V6 rear springs are a lighter weight, which would let the weight transfer happen better for a launch. But I also suspect the rear springs are not that big of a rate difference to make it really worth the effort. I dunno.

I can see the fronts having a big reason for different rates (obvious weight differnce to support), but not the rears.

Yeah he said something about that to me but I couldnt remember.

Tony.

Anyone else have anymore more imput on this.

The v6 spring rate is 95 lbs, the v8 spring rate is 115 lbs. From our experience the v6 springs are too soft. The f bodies don't like a lot of rear squat and work better with a stiffer rear spring. We offer a 1.25" lowering spring with a 150 lb rate. We have several cars in the 7's using this spring. If you have any questions just let me know.

So going with a V6 spring is not the good way to go for good traction or so.

Thanks. Tony.

Springs simply hold up the vehicle at ride height. A lower spring rate such as a V6 spring will compress more than a heavier spring rate V8 or Z28/WS6 spring.

A heavy spring is good for handling. Since it's hard to compress, the car won't roll as much in corners. For drag racing however, you only need a spring heavy enough to hold up the car. The shocks control the weight. If the rear springs are too heavy, the shocks won't compress or extend which is what you want to control the movement of the extension.

A properly set up rear drag suspension will plant the tires hard. This mean the diff is moving down as the body moves up. The shocks are extending. The shocks will have a stiff compression to keep the power to the ground for as long as possible. If the springs are too stiff, the shock control goes to zero.

Put the V6 springs in. If the car sits too low, which will also compress the shocks too much, then you need to raise the ride height back up by whatever means possible.

It's bad to think of springs as V6 or V8. You could have a fully loaded v6 car with heavier spring rates than a soft riding V8 car. Berlinetta, RS, etc.
