Default Another Suspension Question

My '78 Vette came from the factory with the Gymkhana suspension which has the sway bar in the rear.

If I get one of the Performance suspension packages from VB&P, I noticed that they don't have the rear sway bar as part of their packages, should I use my old sway bar, or just leave it off?

Thanks!

Seems to me that if you remove the old sway bar it would detract from the handling of the car. I think I would ask VBP if it will be compatible with their product then make your decision?

The full kit with front and rear springs is designed to work as a package. Adding (or leaving) the old sway bar on will change the handling balance intended for the car.

Well.... just leave it off,drive the car and see how you like it.

Then add the sway bar and see if it improves or not....

just my 2 cents...

We got a suspension kit for my Dad's '78 from them and it had a rear sway bar. I just looked at their catalog and all the kits I saw included one (.75" diameter).

Adding a rear sway bar should reduce understeer, though

If it had a dual mount spring the swaybar would not be needed, they are supposed to make for less roll, just like a sway bar.

I have the 330 vb spring on mine and stock gymkhana swaybar and it works perfect I would leave it on.

76custompaint is correct, this kit has been designed so that the Rear Dual Mount Spring takes the place of the rear sway bar.

I agree. I have the dual mount set on the 2'nd stiffest and have autocrossed the car with several different setups, although I've never tried a rear bar.

I've settled on a 1 1/8" front bar with NO rear bar and have slight oversteer. Adding a rear bar to my car would give me severe oversteer.

Although I'm not to partial to the front monospring, the rear dual mount is a nice set up and like other mentioned before, it compinsates for not having a rear sway bar.

Thanks!!

That answers my question. When I first read 76custompaint's post, it made sense.

I really like the Rear Dual Spring setup. It seems to be a great improvement over the stock setup.

I was not sure myself about the front monospring, but I really liked the idea of adjusting the ride height of the body. I am building a big block for my Vette, and am not really sure how the front will sit. I figured that with the monospring, I could adjust the height to where ever I liked.

Is there another solution to adjustability other than the monospring?

Unleess your doing a lot of Autocrossing i think that adjustability is overrated. You can always cut the coil springs if you dont like the way the car sits. If you building a big block you may want to think about the Street and Salolmn kit. I put this kit on my car and it made a world of difference. the front springs are the 550lb and the lower the car about an inch. My car is a Small block but I like a stiff ride so the 360 rear 550 front work well for me. It is stiff but not punishing. The Blisteins will make all the difference in the world.
