The wheel hop issue is only for the CTS-V

what is this 'hop' you speak of? I've heard people complaining about it but i dont know what it is...
h_h:

If you are driving a V, and launch it from a stop, then the rear wheel will hop while spinning like mad, instead of gripping the road. If you looked at the burnt rubber slick you'd see the tire track, but it would be lighter and darker cause the tire would be bouncing. Its NOT a problem with my 3.6.

The V is susceptable to wheel hop cause the rear suspension is set up to be a little soft so the V still has a smooth but firm ride. Plus when you get on the V, the 400hp will spin the tires! To eliminate wheel hop you'd have to make the rear suspension stiffer.

In the old days you'd put Ladder bars on the car to control traction/wheel hop!

I get wheel hop too. It is really bad on dry roads and shakes the car so badly that I have change flying all over the place. After I switched to the FE4 shocks, Eibach springs, and stiffer sway bars, the hop as been reduced a lot. It still bounces a little but it doesn't feel like a earthquake anymore.

It ahs only happened to me that once, but i had the traction control off. it hopped like crazy and actually my abs light and seatbelt light came on and didn't go off until i turned the engine off. this was however the first time that i just dropped the clutch(had to try it once, but after that never again).

I actually get the hop on my 3.6, brakestanding on dry pavement with Stabilitrak and TCS off. And my Service Airbag light also comes on as well.

I don't get any wheel hop. You guys that do..do you have the manual tranny? I imagine if you dropped the clutch at a high rpm it might bring about wheel hop. With the auto its not a problem.

If you powerbrake and launch it, you'll get it.. Atleast I do.

No power breaking and I get wheel hop. It all depends on the surface of the road...

All I know is this, if your V6 CTS suffers from wheel hop, you guys must be FLAT OUT beating on your car!! I suppose it would be easier with the manual and clutch, but the automatic??

I get wheel hop in my 3.6L 5 sp auto. It does depend on the road surface and the temperature because that affects the level of traction the tire has. Wheel hop is caused by mainy things. What's happening is that as the tire grips and attempts to accelerate the car, the car's weight transfers to the back, the springs compress, the drive shafts twist a little bit, even the motor mounts twist a little bit. This builds up potential energy. When the tire breaks traction, this energy can be partially released because the friction of a spinning tire is less than if the tire was not slipping. Once the energy is released it can start to be absorbed again and this can cause the traction to be regained and the tire stops slipping. This continues over and over with the tires slipping and then regaining traction as the springs and torsion elements load and unload. Because there are so many things involved, you can try to fight it many ways. Changing the springs and shocks can help. Also making the drive train more stiff can help. But remember, its all a system and changes to fight wheel hop can affect ride and harshness of the car.

Not at all. If you're going to launch at the dragstrip, you have to brake torque these cars. I find if I give it any more than 1/3 throttle while brake torquing, I get wheel hop. The first time I did it, I overdid it and the gear shift lever was bouncing back and forth like a paint mixer :D.

It's not hard to get a V to hop. I have driven several of them (since it's my job) and some of them are so bad it would blow your mind... and like I said, it ain't hard to get it to act up.

The bushing kit is an excellent repair for this concern. I did another one yesterday and it was really nice when I backed it out and road tested it.
It's strange that these little bushings you put in fix that problem so well.
Sometimes you end up with some chatter from the bushings, we are still working on addressing that one.

James has tried a bunch of stuff but I guess his car is just mad at him.... :D
You know what it is James? It's because you had Ray put them in and not me... LOL

Oh thats what it is!!! I get HORRIBLE wheel hop! I cant do a burn out because the wheel hop is so bad. I've even revved the car right to 6000 and popped the clutch and it feels like a bunch of qick thuds in a row. I try not to do it because it feels really bad for the rear end of my car. The only time I don't get that when I'm tryin to launch is if I'm going to flip a bitch and have my steering wheel turned, then the ass end breaks with no wheel hop. I thought it was just from my 20" rims, but i guess not, I want this fixed if its not normal!

Haute,
Maybe you need to visit the V Forum. Some fixes are in place.:yup:

Hmm, I've powerbraked mine a few times with TC off and all I get is a bit of wheelspin. Then again I only have the 3.2...
