'22 SB401 Dry Clay (low traction)

Post by Blawson13 »

I am running basically the manual setup on an indoor low traction dry clay track. Any suggestions on how to make the rear end less loose? as soon as you throttle from a turn or a jump, the rear end spins around like a 2wd buggy. Running 7/30/5 diffs and rest of car is et up according to manual using black springs and low temp shock oil settings. 13.5 Stock racing
TIA

Consider the following setup which has worked well for me in low grip, only change would be 7K in the center diff to settle the car:

*** Note that the rear sway bar is removed completely!

If you still need more grip, then consider increasing the ride height up to 20/22 as needed

Thank you Bill,
Update: I ran 10/10/7 at the club race and it was a very noticeable difference for the better. Along with other changes to the set-up (low RC) and diffs, we were able to knock off 3 secs a lap from the last weekend. Good enough for a 1st in B-Main. Rest is driver ability I believe. I would be happy to post set-up sheet, but I don't have an editable sheet or know where to get one.
Thanks again.
