thanks for the reply.Am going to try a higher pinion because the car is running warm so maybe push it out to a 24/25t am running a 78 spur gear.
I've been looking at servo's the bluebird range seem to be of good quality and alot at are club run them and seem to be happy.
Also maybe i need to improve my driving because its my first x6 i dont think am driving it aggressive enough, x6's hold the corner line well i tend to drift it into the corner and throttle up once am straight.
Put its going wide on fast little corners ,thats why i need to change the servo because its just not strong enough...loving the car
so balanced on the jumps....
