Sounds like axle wrap. You may need new leaf springs. Do they sag? If you really what to stop the wheel hop you need traction bars/ladder bars.

or just take off without the gas pedal to the floor

...i think that's why they made sports cars, man. For doin, you know, sporty stuff. Like burnouts, drifting, drag racing, pavement donuts, etc.

Unless, of course, this is your jeep....

TRS80 has it pegged.

Axle wrap or "wind-up" is caused by largely by pinion angle and weight transfer along with parts that aren't designed to be power-braked at the stop sign.

Basically, if your car SQUATS when you hammer it, your pinion angle is wrong which causes the weight to unload off the rear allowing the axle wind-up to release (it winds up, releases, winds up, releases over and over - that's what causes the wheel hop). If your car's hind-end RISES upon hard launch, the weight transfer is correct and is causing the AXLE to be forced into the ground and the body to lift in reaction to this. The lifting of the body is how you know the axle is being driven downward thus creating traction. The axle can still hop but doesn't want to as badly.

Do some net research - all drag racers understand this issue well. I even have a book out in the shop this exact subject...can't remember the title but I'll dig it out and report back. I think it's "How to Make Your A-Body Launch" and refers to the GM A-body platform (Chevelles, GTO's, Skylarks, etc.) that have rear control arms and coil springs. They are notorious for poor launch.

Meanwhile, read this: http://www.hotrod.com/techarticles/t...ons/index.html

It covers the basic issues for both coils and leafs. It is not hard to cure...but the solution has compromises.

In the end, I like dyte2004's answer the best...

Stop doing burnouts, checks don't think they're cool and it breaks stuff.

This is pretty common with all vehicles with leave springs in the rear

wheres the fun in that? lol i know its not a sport car but i still like to have fun. these things were the quicker suv back in that time and i cant really go wheeling yet b/c no good tires and/or lift.

I found this

maybe could help? It isn't a permanent solution but might be the least invasive one.

lol hey its your car but i wonder why you dont have good tires these jeeps really dont like burnouts besides only one wheel spins on most of them and the d35 is not a super strong affair

have fun till it blows and then get a better rear end and the burnouts will be out of your system

agreed ^
