cal trac woes

hotrod68 said
I went to a trans brake in my dart and i'm having one heck of a time with crushing the slick causing it to wad up and unloading the back tires. I've tried switching to the bottom hole on the front of the caltracs and no change. I have the calvert shocks on the rear and have tried full loose rebound to full tight I even switched to a stiff sidewall slick, which helped very minimal. Slicks are 29x10.5w I've went from 14psi of air where i think the rim about drove into the pavment up to 20 psi where it just blew the tire off. I have more then 5 inches of front end travel with qa1 adjustables, I've slowed the front end down and fully losened it. How can I keep this car from crushing the slick so bad? It's very violent out of the hole, The car has been a best of 1.32 60ft before the trans brake but i suck at footbraking. Any info would be great, I'm about ready to back half this thing and put big tires on it

You need a lot better shock and double adjustable at that and whenever you are experiencing too much hit on the tire you need number 1 to be able to tighten up the extension so the hit isn't as hard and then you will need to number 2 control the hit with compression as the only thing that tire wants to do once it gets whacked into the track is bounce back up and tightening the compression will help it stay down. Obviously shock adjustments take time to get each person's car and setups figured out but what I described is the general jist of it. I wouldn't do anything with the CalTracs themselves until you put some good D/A shocks on the car and another thing is you will be faster with a drag radial but maybe you have a certain reason you want to run a slick. The car does not need to be back halved and huge tires to make it work correctly but you will need some good shocks.
