I think the ceramic diff balls will be my next purchase. the diff (for some reason) seems to atract so much dirt into it, it rediculous.
I stripped it down before the bury meeting because it was making a horrid gritty noise and the balls were really dirty.
then after running at bury it feels the same again.
so its time for another strip down and to purchase some new balls!
Also it may be worth to get some titanium turnbuckles. as i managed to snap one of the std ones on its first test, due to a awkward landing. I just used some of the lundsford B4 ones.
