I tried searching but couldn't come up with much.

- Are the V6 springs better for drag racing? If so, why?

- Is there enough of a difference to make it worth the change?

- Is it only certain year V6 springs, or any 4th Gen V6?

Thanks for helping the suspension newb.

No, they suck..too high and too soft.

You want to transfer the power to the Tires, not let the Chassis absorb it.

The best setup is lowered, hard Suspension and soft Tires so they flex, allowing the power to go right to the ground.

That's the way I have my car setup, and it gets off the line quick..

The v-6 rear spring have the same rate as the ls1 rear spring. As the other poster had stated you want the rear stiff on the f bodies that workss best. Alot of our customers use the stock spring in the rear and do the heater hose mod. It lowers it a little but the rear spring is still retained.

1LE springs here with the hose mod to lower the ride height. The 1LE's have a higher spring rate then stock Z's. I also have an airbag in the right rear.

Heater hose mod? Would someone like to enlighten me?

Take the Spring Isolator out and slide a Heater Hose around the top of it to absorb the shock. It lowers it.

Only the 93 - 97 V6 rear springs are softer, I beleive their rate is about
95 lb, and the V8 springs 113 lb (z28).

V-6 springs are not the same rate as Z28 springs, front or rear. They are lighter. Around 100 lbs/in vs. about 115 lbs/in on a Z28. The length also changes too. In fact, the 93-97 V-6 springs are different from the 98-02 V-6 springs, and as are the LT1 vs. LS1 springs. The differences are subtle in the rear especially, but they are there.

If you want to plant the tires harder you want to work the suspension to provide more anti-squat. A little change in rate (or staying with the same rate isn't really how you best accomplish that). Lowering springs do also tend to be lower, and much like they lessen body roll, they lessen body pitch. They are not ideal for drag racing, and it sould be noted drag srpings like the Eibach kits are quite tall, and soft (and use an airbag on the RR to tune).

The 98-02 v-6 springs have the same rate as the 98-02 v-8 springs. Your right sam the 93-97 v-6 are lighter, guess i should have clarified which model i was referring too. The f body cars work very well with a stiffer rear spring. Our customer cars that cut the best 60' times have very little if any squat in the rear of the car. A good set of adjustable shocks set to a stiffer setting do the job quite nicely. If you take a look at the cars on BMR TV you will notice that they all have very little squat in the rear.
