The two traction compounds that are popular here are the Niftech and Jack the Gripper. Personally I think Niftech works better.
I think what I need to do is use less compound on the front and full on the rear.
I have 50wt in the front and 40wt in the rear. I run it about 6mil ride height at the front and 5mil at the rear.. was told a smige more in the front helps with transfer from back to front and takes a little steering out in the corner.
I am running the stock 87 gear with a 27t pinion at the moment on a 19t dynasty handout. I am not worried about the speed at the moment.. its more than enough to turn laps in the hi-c main.. low b main range... we have about 24+ 19t drivers on a club race day. My problem is staying smooth at the moment.. the car is squirly.
The car is running with a centre one-way.. not front. Wonder if I should go back to the direct drive adapter and see if the added braking will help me control the car better.
One major problem with still running this car is new batteries.. 3800 and 4200s dont fit well in the slots... OH well.. I have lots of good 3300s
I think there are some sites to calculate rollout.. so I will try and figure out just how far out I am on the pinion.
