Hmm, having some problems with my E4 (the first version) it is al updated, with the French Lightweight spool in delrin front , Xray CVDs and som special belts in rear and front.

to the Q: i bought some plastic pulleys for the side-belt...but it wont fit, the belt is so (how ya say it?) HARD, that i can bearly move it with my hand, and i was forced to use real powa to get it on..this wont go, so i have to get back to alu side pulleys again...is the side belt diff on the other E4 cars? let me know
