Common problem. Try lowering the back 1 inch. Good luck and let us know how it works.

There was a huge discussion on the effects of wheel hop on the CF awhile back.

But I just don't know about lowering yet.

I don't know if I can afford a $1000 set of tires every 2 months...

I'll wait till some of these guys hit 15K or so and see how their tires are holding up.

Who can you trust to align your Z?

Mine is lowered (same as JLA's)and continues to wheel hop. My best 60' time at the track was a 1.9 - that was done letting the clutch out at around 1500 then going full throttle. If I tried launching at higher rev's it resulted in over 2 second 60' times. It would take an excellent surface to launch at 2400 to 2700 and get the needed traction to achieve a 4 sec 0-60 IMHO

Jim,

Thanks for the report. As an old drag racer, I love hearing about performance!!

I was in Orlando back in September and met up with Steve Hummel and a GM Engineer. He's actually the same guy who is helping to get the Z06 Tire Sealant fiasco straightened out. I'll post on that later in case you haven't heard.

Anyway, he was telling Steve and I about some of the Generals professional drivers and that during testing of the Z06, they were able to get consistant 3.87 0-60 times.
He said their method was to launch at 2900 RPMs, but they were slipping the heck out of the clutch. He recommended that we do NOT try this because they were really smoking the clutches. You may remember that the first Motor Trend test car had a bad clutch in it. Now you know why!!

I love drag racing and running all out, but I'm in the same boat as JC, I can't afford to be buying a $1000 set of tires every couple of months either.

One of these days I'll have to post some pics of my old Junior Fuel Dragster that I ran back in the 70's.

I shure hope my cluch lasts longer then a few months. I use slight cluch slipage to get a good launch and to minimize the wheel hop. 1.79 60'. The trick seem to be 80% cluch for 2-3ft then smothley engaging cluch and throtle. Ric

I lowered my Z, and it helped, but the wheel hop is still there. Sacramento raceway seems to be particularly bad for wheel hop, and using nitrous compounds the problem.

Spraying my 150hp shot, I actually went SLOWER than my 100hp shot because I was getting wheel hop in 1st AND 2nd!

Mt wife bought me a drag racing book for xmas, and it has some tips for setting up your car in their. They mention that coil sprung suspensions, such as that of the C5, are prone to wheel hop by design. They suggest using a stiffer shock absorber, and installing "air bags" to reduce the movement of the suspension.

I don't think there is anyone currently making airbags for our application at the moment, so basically we are hosed!
