Suspension Problem, Help Me Out!

[Zach94]

I recently got the Eibach Pro Kit put on with everything else suspension staying stock. I now have a problem with wheel hop. How do I fix this? What do I need to get? I don't know alot about suspension so please help me out.

You will need lower control arm relocation brackets and an adjustable panhard rod. While your at it you may want to change the stock lower control arms as well. Lowering the car changes the suspension geometry, you now need to put it right.

Where the best place to get this stuff?
What stuff is the best to get?

"What stuff is the best to get?"

Check out Hotchkis, BMR, Granatelli, SLP and Spohn http://www.hawksthirdgenparts.com/sp..._parts?start=0

I'm sure there are many others.

All you need are some form of aftermarket lower control arms.

A panhard rod will not fix wheel hop due to acceleration... it will fix wheelhop in a corner.

Do i need the LCA relocation brackets to?or just the LCA's?

Here's my opinion on what you need, and, once again my opinion, more important _why_ you need it, so you can make good decisions for yourself. Slapping parts on your car because some guy on the Internet thinks they're right is often a really bad idea.

When you put stiffer springs on the car, you overwhelmed the ability of the stock shocks to dampen their movement. You need shocks. Bill Strano is the guy to tell you which ones.

When you lowered the car you screwed up the angles of the rear suspension. The lower control arms now point up as they go forward, not good. Relocation brackets will fix the angle. They usually have more than one position, level lcas are good.

The bushings on the lcas can flex in bad ways. The above problems make that flex worse. The lcas themselves are generally strong enough, even stock lcas. 1LE lcas are cheap and have decent bushings. Some aftermarket lcas have bushings that only flex one way and are good for drag racing only, you don't want those if you want good handling on the street. If you don't go 1LE, ask the manufacturer, they'll usually tell you.

Once again, my opinion, Eibach should give some info on all this when they sell you the springs.

Are these the products you were referring to?

I have the pro-kit springs too. I didn't need an adjustable lca, the rear end is centered just fine on my car.

I had some wheel hop before the springs. I put 1LE lower control arms on. Got rid of the wheel hop. The stiffer bushings did the the trick.

Then I got the lowering springs. I have a little less traction now, but still no wheel hop. Less traction only on initial launch. (60' times are about .1 second slower)

The rear wheels try to rise up into the car at launch, when the control arms are angled down from the differential to the frame. (the car looks like it tries to squat down in the back).

Once the rising of the wheels is done, traction is the same from that point on. This only takes a moment, then the suspension stabilizes. With the springs being stiffer, there is not that much squat taking place.

(I do have better shocks, you eventually need upgraded shocks with stiffer rebound valving to match the force the stiffer springs put on the shock when the car tries to rise (and the wheel drops), but this is not related to the wheel hop problem, just handling in general...)
