Hey Tarnjit,

Glad you like the car, I found that the rear end of my car was quite unpredictable with the centre one way loose. I found that if you loosen the spur mount and rear pulley and pushtogether and tighten so that it tightens the centre one way, it helped alot. I dont know why because its not tightly locked but tighter!! I now run with a centre locked pulley i made by glueing and pinning 2 fixed pulleys.

I read a quote that if you put spacers under the rear blocks it actually decreases grip, i thought that was the opposite, if you add spacers under wishbone mounts it increases grip (reading any other manufacturers manual)

Are you using blue rear 1deg hubs? If you are then you need more toe on the wishbone but if not forget this

Rear Diff, i found that if the diff was loose it gave the unpredictable rear end, problem i found was that it was hard to do up because it would only do up certain amount then couldnt tighten any more (solution is to glue the 2mm nut into the plastic T piece) just a few dabs. Then you can tighten the diff a bit more. Its not just bout it slipping but how loose it feels.

Lastly as i know bedworth track i know that its probably off power when the back steps (going into couple of those hairpins) so i would definatly try playing with droop.
