if ur cars kicking out run 52 japs on the front with superglue run around the outside rim if ur car understeers go down the compounds on the front
i was 2nd mardave national my brother was first
once u have the car balanced u should be able to run 100% on everything on ur speedo and crave more speed
rear diff should have 12 balls and run as loose as possible before it slips
and dont forget the nylon battery trays i make the cells run flat on the chassis lowering the centre of gravity and u can run ur cells offset to counter the motor
1st 2nd 3rd and 4th at the nationals
if u use lots of additive on the rear u should use 2 pairs,one one week then the other the next giving them time to dry out ,additive will soften the tire and ruin the that why one week u will go ace the next e final
then u can play with shells and small tune ups ,there the bits u fine tune the car with

Definately some good tips here. Ive been running silicone tubing on the front for quite some time (before i semi retired from racing and now making a return) Im going to experiment this time around with some nortech whities instead of the tubing. I think the degree of castor depends on the tightness of the track, but i always run a minimum of 2*1mm washers under the front of the wishbones (2deg castor) just for stability if nothing else. The tip about tyres and additive again, good tip, not tried it, but certainly makes alot of sense.
Spomething that i have found alot of people doing at my local track, is not using the sub trim to centre the steering servo properly, simply leads to unbalanced steering, doesn't sound much of a tip, but makes quite a big difference.
