Wheel hop

You guys should try running a 1/4 mile at Sacramento raceway! Anything more than a soft launch at 1500 rpm and you will be hopping for most of first gear.

Add a little nitrous in to the mix and... well, it's not pretty!

My car was dropped in the rear to the limit of the stock bolts. I have launched hard at least 30 times and haven't had wheel hop. My '99 FRC would wheel hop you off the road.

SWCDuke put up an excellent review of the 06 on the CF, C5 general section. In his evaluation of the car he tried to launch the car and test GMs 0-60 claim. He indicated that launching too soft would result in wheel/axel hop, and too hard excessive wheelspin, and that there was a small margin in between for a good launch.

I find this quite interesting, and I am always trying to find ways to a better launch. My car is lowered, max in front and low, but not maxed in the rear, and I found it has helped some, but not eliminated the problem.

The last time I was at the drags I had limited sucess until I starting spraying big shots of nitrous, and then it was wheel hop city all over again. I have a window switch, so the car was moving at a decent speed before the nitrous kicked in, but the addition of all that power was too much for the suspension to handle, and I hopped through first and second, resulting in a slower time that NA!

I think I need to try launching harder and slipping the clutch as someone suggested above. I haven't been able to break 2 second 60 foot times with my current technique

Hey DJ Z06! I see you're here now. Hoosiers hop like crazy too and they are much lighter than Kuuhmos or Goodyears. The C5 doesnt have the outer trailing arms that C4s had and is more prone to rear bushing compression and rear toe-in under acceleration causing the hoping. I think a heavier wheel/tire is going to make it worse. Only a gentle launch (clutch slipping) is going to keep it under control.

I've only launched my Z hard twice. I haven't experienced any wheel hop yet. The car has been lowered...don't know if that helps or not. Traction was the biggest problem. Actually I don't like to launch hard because I don't like spending a $1000 for a new set of tires every few months.

There are things you can do that seem to help. In my 00 coup I had the F45 and seting it on performance helped. In this car you have to "get it rolling" before you give it alot of power. So if you need the ET'S on a street tire you HAVE to leave between 2500-3000 engage cluch 75-80% for the first 2-3 feet then smoothly engage cluch and power.(Track conditions determin rate)it realy is posible to DRIVE around wheel hop. My best 60' time so far is 1.79 on a good track whith some more seat time I think 1.70 is posible with the F1SC's. Ric

Bingo! Give the lucky winnah a ceeegar!

This is how 60footers are done and how 0-60 gets quick. Congrats. Old school, hard on the clutch, but quick.

What does the slow clutch release do to clutch life?

It will F%^KUP a clutch real quick...the price ya pay for going fast!!

I've been to the drags twice. Once completely stock, once lowered to the max of stock bolts. Both times were exactly the same. I don't like slipping the clutch, so I launch by popping it at 3000 rpm. some time the wheels will spin controllably with no hop and away you go. I've done a corrected 12.21 at 120 mph. Other times it seems like the car bites harder and the hop begins. It costs me half a second each time it does that, about half the time. I don't drag enough to worry about it, but it is too bad, because 06s are killer except for that.
