Suspension Upgraded - Still have wheelhop

Please get your alignment sheet and post it up.

Don't have it. But next time I will pay more attention to the alignment and use the spec advice from here. I have been doing some reading since my last post and I am of the opinion now that my wheel hop problem may be due partially to alignment and partially by the rubbery stock outer trailing arm bushings. I might as well do those before I bother with the alignment.

While i am at it I will turn my attention to the front of the car to finish my suspension upgrade. I will do my research this time to figure out how to improve steering response.

I know lighter tires and wheels will help but i don't want to spend that much right now.

And I also will be looking for a tunnel brace with additional clearance so I can get rid of those washers. Is a Camaro ever really finished?

What wheel and tire are you running at the track??? I have more power with less suspesion mods and very little issues with wheel hop!

Replacing the knuckle bush for the trailing arm won't hurt anything, but I am not sure it is necessary.

This is cake and more predictable than wheel hop. Add a set of EP6579 radius bush inserts and tweak the front alignment.

Camber: -.75
Toe: ZERO it out

Drive away from the alignment shop with a good on center feel and much improved turn in.

It would, but we should be able to get her settled down with them.

No.

My notes are in Pedders RED.

The outer trailing arm bushing will definitely help you out. The toe rods don't have any additional busihngs since they mount directly to the rear cradle and the spindle.

Those two bushings will definitely help you out some as well as a good performance alignment. There are many variables that go into wheel hop so many times it takes more than the parts you have to cure wheel hop on the manual cars. What tires are you running? under what conditions does the wheel hop occur?

Stock tires and wheels. I want to cure my hop before I go to the track. I experimented trying to launch from a stop and also just by punching it while just moving. It happens when it was warmer last summer and now 50-60 degrees out on a clean tarmac surface.

By the way does your center tunnel brace have any additional clearance over the stock unit?

Also would you any additional recommendations fro the front besides what Justice Pete mentioned?

Hey, thanks for your help and taking the time to sort out my rambling. I really love a good handling car and this one is getting close.

Stock wheels and tires for now. Maybe DRs later after the wheel hop is cured or at least under control. I have had a number of mods done. Not the right combo for my car yet.

Maybe it's me.

So while you are tweaking her, you are lusting for a 1LE Z/28. Now we know what is causing your wheel hop. She is

A good set of tires will really help out with the wheel hop also. The stock tires don't do anything to make the wheel hop any better.

Our tunnel brace does give a little additional clearance and if you needed more clearance you could always space it down a little bit.

I would definitely recommend doing the radius rod bushings and even the lower control arm bushing if it was in the budget. We like to run a little more negative camber than he is recommending but either way will work.

Sorry this thread is a little old. But that was funny. I just can't help myself. I am such a slut.

Followup. I finally put those Outer Trailing Arm bushings on.

Good results. Wheelhop gone. The car hooks much better. And the little bit of step-out is also gone. Straight as an arrow.

I'm glad I read this thread. I just ordered trailing arms and was going to try them to cure the rear end hop and if it wasn't what I want, change the outer bushing as well...but, I think now I will just order the new bushings as well. Thanks guys, good discussion and a happy ending for the OP (and me).

Glad to hear that. Now go have some FUN!

It is definitely a good idea to do the outer trailing arm bushing along with the trailing arms. There is labor that overlaps and they make a pretty big difference as far as performance goes.
