TLR 22 front shock shafts are too short. I just got back from Hobbytown. Talked to another racer that went thru 2 front hinge pins and an A arm already.
Bought a set of TLR rear shock shafts for the 22b for $9.00. That's half of spending $18 on a full set of pins, 4 of which I'll never need. (jinxed myself now) 3mm nuts at hardware store were 11 cents each. Cheap fix for now. I have to get a handle on spending money racing/crashing toys!
