Sorry, I didn't see the rear brakes only in original post. Just saw you said it was diving hard on the brakes.

I have years of experience with most tires applicable to sand drags. Sand racing since 1980. The thing that makes it hop in the shutdown is too much brake pressure. If you slide the tires sand or dirt will pile up in front of the tire and when you go over it the car will start bouncing. A quick stab on the gas will settle it right down or just coast a bit to settle it down. I like to roll out a ways and then lightly run the brake and then progressively harder as needed to hit your turn. The range of pressures we use doesn't seem to have a big impact on bouncing or not. They are just big bouncy tires now matter how you look at it. A softer shock might help verses a stiff one. Solid suspended cars seem to bounce worse yet.

On STU 20.00 the pressure range is 5 to 10 pounds. You don't want them too soft or the cups fold back and you loose traction. For braket racing a Skat Track Hooker with Kevlar will be ideal for this application. I run 18 cups on a 15.5x33-15 on 16" wide bead locks and run 13 psi. I 60' in the 1.27 to 1.34 range depending on the track. If it wheelies hard you can dump some pressure to kill the bite. I recommend at least 5" ground clearance to avoid big clods when the track is wet. We have altered type cars running 3.3's on 20.00's using small cubic in comp style engines to hat injected big blocks with over 1000 horsepower.

Put some Smoothee's on the front and run then at 15 to 20 pounds.
Best pass during 2015 races 3.092@104.4mph at Albany OR. All motor single 4 on race gas.
