Jeff: Some things to consider. Make sure rear is square to engine centerline. Check circumference of rears and make sure pressure is equal. If you have a double wheelie bar, make sure it's not steering the car on launch. Adjust the rebound on rear shocks softer. If they are stiff and you go through any bumps, it will pull the rearend up off the track surface and you start to spin the tires. Hope this helps.
