Too much traction! Need launch help! After spinning the daylights out of standard radial tires (Kumho 712s) for several weeks, I stepped up to M/T 255/50-16 drag radials for more traction. They don't spin. Not on take off, not during shifts, pretty much only when I do something severe like dump the clutch on my slippery coated driveway. Traction is normally a good thing, but my nearly stock M6 Camaro now has a serious case of the "bogs" during launches -- on the track and the street. Any suggestions for getting the car "out of the hole" without bogging?
Thanks,
Thanks,

My 60-foot times did not improve much in this first outing with the DRs because I traded excessive wheel spin for excessive engine bog. I think it is time for some 4.10 gears to get the car moving and out of the "bog zone".

I tried launching the car at 3500-4000 rpm and slipping the clutch, but the stock clutch kept on slipping through the rest of first gear when I did that. If I launched high and engaged the clutch fast, then the car would bog down to 3000 rpm and have to pull itself up again. I even did a "spin-then-bog" combination when the tires actually turned over a few times before biting.
To get to 4000 rpm and avoid the "bog", do I need to slip the clutch until the car it going 35-40mph? The stock clutch may not survive doing that more than a few times...
Would a set of 4.10 gears help cure this?

Becareful with that 10bolt launching that high 
Or break it and buy a 12 bolt or 9" and go launch at 5,000rpm!! I broke my 10bolt on Nittos launching at between 3000-3500rpm 
stupid 10 bolt, but the 9" is on the way.

I wouldn't slip the clutch that long you will fry it and need a new one! But thats a good thing because the car will be easier to launch with a new clutch, atleast i thought so.

theres a few things you need to have on a car to get rid of the bog and you dont have any so just pick one and go from there, lol
you need a better clutch cause you will need to launch higher, then you will need a rear end, then you will on borrowed time with the drive shaft. welcome to the point of no return

Thanks for all the replies! 
I have the tires at 31 psi. Same pressure at the track too and they stick like glue!
I went out and practiced launching some today on the local streets and I am getting a better feel for walking the clutch out and feeding the gas pedal in to get the car to launch without bogging. I just need to keep practicing.
4.10 gears would help, and I am leaning towards getting them, but will they make the 10-bolt even more wimpy? Would a heavy-duty rear cover help it survive?

I have seen this with many at our local track. I even had the problem a long time ago when my car was first coming to life. Just like everyone said. gears gears gears!!! They won't last in your 10 bolt, so just save the money, stay away from the track to protect the rearend you have now, and through something underneath your car taht can handle the power/gearing. That is the best bet.
Do yourself a favor... save those tires for when you have a rear that can take them.
A 12 bolt, clutch and driveshaft are in order. Driveshaft and rear go hand and hand, I'd do those at the same time... and your stock clutch would be a good thing to replace while you are at it.
It's a hard 4 to 4500 bucks to swallow, but the thought of being able to drop the clutch at 5K and not worry about those things breaking, priceless.
I went the e.t. street route ( radials weren't out when I made the purchase ) and the stock clutch took a crap on the 2nd launch... same problem you are having. F1 goodyears at the track were a joke, so I got a set of bogarts and 26 x 11.5 e.t. streets... traction problem solved. First pass I made, my car bogged so bad I thought it was gonna stall... 2nd laundh, I tried 5000, stock z06 clutch up in smoke... and that stunk for a day or 3. Spec 4I, 12 bolt with 4.10's, steel driveshaft, Spohn 1 inch solid swaybar, cam and associated parts all in... I figured the added Hp wouldn't hurt for this year either
Get that drivetrain done asap.... before you get a tow bill to get the car home, that takes away from mod $$ !
