Walter I went to a new to me indoor clay track that I was informed was high traction. So the 1st race I had the laydown tranny in using the aluminium arm mounts on the rear, 3 degree toe, 1 degree anti squat, no added weight, no tire sauce on brand new gold dirt webs. Rear end was loose! I threw a bunch of lead on the rear and bummed some blue liquid wrench and salvaged a decent finish. For my 2nd trip this past Sunday I made the following changes still with lay down tranny. 25g c mount, 12g d mount, camber link middle hole on tower, hub 2 hole up, inner hole. Shocks on back of arm, 2-1.7 piston, AE 27.5, AE green spring. 3.5 degree rear toe, 1.5 degree anti squat. Treated rear tires with blue liquid wrench over night. I now have a on power push and would not hurt to have some more off power steering also. Hope this helps.
