traction problems

[dalejrfan8]

I run my T3 on my backyard track. It is hardpacked and the top layer is very moist but not muddy. The rear of my car spins out exiting the corner. Can anyone help?

If its clay like try WD-40 or Simple Green on your tires. Here the tires hook up real nice and its wheelie time out of the turns. Another is to check your diff or slipper, might be too tight.

Ok, raise the back shock clamp so that it will let the back be more soft, to let it grab better, and then tighten front down, to take some of the front bite away

I changed the shock settings like team said it helped but the problem was still there. So I loosened up my slipper. That made it a lot worse. I also loosened the diff and that didnt help much either. Am I doing something wrong? Maybe I need different tires?

Hey guys I think I found the problem. There was a bad bearing in the left outdrive of the tranny. Do you think that was the problem? I guess I should have looked at the drivetrain first.

if it only would slide out in one direction, than that was probably your problem

dalejr - on any AE truck tranny, NEVER loosen the diff. That is never going to solve the problem and could lead to a melted diff gear, the balls get hot and melt into the gear.

I was really REALLY surprised that loosening the slipper made it worse, so let's hope it was the bearing. Was it hanging up on it at all?

Hard to medium pack soil that's damp is PERFECT. :D Doesn't get you all muddy but the moisture should give you good bite. What kind of shape are your tires in and what are you running anyway?

A decent mini-pin or step-pin tire should give you plenty of bite, and if you're spinning out on ACCELLERATION loosening the slipper should indeed help you get out of the corner without spinning (slipper slips, not tire.) If you're spinning out on decelleration or coasting, your speed control is set wrong. Set it so if you let off the throttle it coasts, not brakes in. If it brakes in, it will spin you out every time. (You can fiddle withh this to get a touch of drag brake later, but if it's actually braking it will spin you out.)

PS On the AE trucks raising the shock clamps doesn't soften the shocks, it changes the ride height, they are two different things. If you want softer shocks, you can put softer springs on - or lighter oil to allow them to react a little faster and get a little more weight transfer out of the roll. You can also try a different shock mount hole, but all of these (except the springs) are subtle tweaks, not for getting rid of a major problem.

rocknbil hit the spot. If you dont want to throw down for new tires, go with lighter weight oil to get the truck to roll more in the turns allow the weight to shift and more frip on the outside. I race on the same style track your describing and the Bow Ties hook up and the truck handles like its on rails. i go full bore into a hairpin, let up and turn and it'll path a nice turn right around it. The only problem i have sometimes is keeping the front end down since we have a tight quick track that requires lots of low end torque and the bow ties hook up almost too well.

The bearing was starting to pretty bad. As for my tires I run Bowties, but after runs on the pavement (Big Mistake) they are a little worn out. I planned on getting new ones soon anyway.
