Wheel Hop on Prep Track
Ran my turbo c5 at the track day and all 13 runs I had major wheel hop on street tires. What can I do to stop the wheel hop on the track. I do many digs on the street and never wheel hop. Thanks to the wheel hop the best I could do was a 12.5 sec @ 120mph with a 60' 2.6sec.

Get a drag radial and learn to drive around it. 13 runs..cant believe you didnt break something!
There are other products out there said to help but not familiar enough to pipe in on that.

Fat sticky tires will help... coilover I hear help, metal end links, rear end alignment, even dropping a few psi in the rears may help a bit... are you running run flats?

I picked up some 28x10 Hoosier Slicks.. Hope they helped but was seeing if there was anything else I can try too. Everyone was surprise I did not break anything at the track too.

I was running Pilot Super Sport (not run Flats). I just picked up some 28x10 Hoosier Slicks. Hope they help.

You most likely are experiencing wheel hop AND drivetrain shake.
I have found out that the following things "HELP" prevent it but not totally eliminate it:
1. QUALITY SHOCKS. (I installed C6 ZO6 on my 02 ZO6 and it made a big difference in drivetrain stability and the cars ability to perform emergent maneuvers! NO MORE skiddering side ways when taking high speed turns
2. Differential mount. Pick up a PFADT Mount or get a good poly mount.
3. ENGINE MOUNTS. If yours are OLD/SOFT/DETERORIATED, it will allow the drive train to shake during launch. Get new GM ones or install some quality firmer aftermarkets.
4. Rear Wheel Hub Bearings. Check your rear hubs and see if the bearings have any excessive slop. Jack up the rear and do the 9-3 & 12-6 O Clock push pull on the wheel. If you have excessive SLOP in the rear wheel bearings, replace them. They will wobble under hard acceleration and cause all sorts of funky issues.
5. LIMITED SLIP CLUTCHS.. Put the drivetrain in N, E Brake OFF, jack ONE WHEEL off of the ground (other wheel on the ground)... Try to turn the wheel that is off the ground. There SHOULD be a lot of resistance to rotation but you should be able to break it free.
Do the same to the OTHER WHEEL. The force that it takes to break the wheel free, SHOULD be the same or close to the same force. If one is very easy and the other is much harder to rotate, you have a broken Belleview spring or bad clutches.
6. Tire Pressure. Make sure that they are the same pressure and correct for your track conditions.
Like "Tony Le" stated,,,
I'm very surprised that you didn't break anything after repeated thrashings. Wheel hop is the leading cause of differential breakage.
That's my 2 cents...
