Wheel hop?

[2011 SS]

When I lose traction I get a crazy amount of wheel hop on the street, as well as on the track. Does anyone else have this problem?

Thanks Sorry about that

Think about anything street related the same as fight club, and the number 1 rule of fight club.

With that being said, I never have an issue with wheel hop. If you are getting wheel hop you are doing it wrong. The point of launching is not to get wheel spin and hop. You just need to feather the clutch more, and ease into the throttle for control. By the time your hitting second, you can go full tilt boogie ... Have fun and stay safe.

The Book on 5th Gen Suspension is a great place to start.

It is pretty common. When your car begins to accelerate various bushings and suspension/chassis components deflect. Under normal driving conditions this flexing is negligible but when the car is launched aggressively the deflection causes significant toe changes which reduce the contact patch of the rear tires. This leads to a reduction in traction and momentary wheel slippage which then alleviates the toe changes and allows the rear tires to regrip. The vicious circle then continues as the suddenly improved traction again results in deflection and toe changes leading to wheel slippage. The main culprits causing all of the problems are the rear trail arms and toe rods along with the rear cradle and differential bushings. Feel free to hit me up if you have any questions.

The 2004-05 CTS-Vs have a severe wheel hop problem; they can barely be launched at all without hopping to pieces. A lot of the V guys buy anti hop kits or better hop-proof axles...I'm sure there are some out for the Camaro

I had that issue but replaced my lower trailing arms with Pfadt trailing arms. Problem fixed.

Yep, probably bad shocks. Put it on the rack and check for leaks. I didnt have W.H. but did get a leaky shock which GM replaced under warranty.

Yeh what he said.

Wheel hop is a harmonic instability, a resonance in the suspension. It starts out imperceptibly and reverberates through the IRS until it explodes in a violent and sometimes destructive action.

Wheel Hop is Caused by:

• IRS sub-frame twisting in the voided rubber sub-frame bush mounts
• Deflection in a number of rubber IRS control arm bushings
• Spring rate
• Damping map
• Tire composition
• Tire rolling diameter
• Unsprung weight
• Pavement condition
• Moisture
• Driving style
• Alignment
• Tire inflation
• Loose bolts
• Defective parts

We could add more to the list, but it is sufficiently long to give you an idea of the variables. There are many that would just throw parts at the problem. That doesn't make sense to me. A bone stock Camaro should deliver a very good behind the wheel experience without the need for my parts. Obviously I believe we can make it better, but it shouldn't be significant on a bone stock Camaro.

The first place to check is wheel alignment. Negative camber puts a heavier load on the inside tire shoulder than the outside tire shoulder. A bit of negative camber is fine. A lot of negative camber has you launching on 2/3s or less of the tire. The smaller the tire contact patch the easier it is to induce wheel hop.

As I said earlier, with a good description of the wheel hop you are experiencing I can provide a more specific response. There is a great resource here on Camaro5 THE Book on 5th Gen Suspension. Set aside some time and read through it. You'll gain a thorough understanding of your 5th Gen suspension and be able to make informed choices.

The other problem that Pete did not mention is that these cars are meant for spirited driving, just not full out in stock configuration. Change a few relatively inexpensive parts and you can drive this car full out without wheel hop. My '10 puts down 650 rwhp and I get some spinning but no hop from my M6. If you want it to go away you have two choices... drive less spiritedly or call Pete and he can take care of you like he did me.
