Some good advice and fast yokomo F1 cars here. Unfortunately mine is not fast and turns like a dump truck but in all fairness I'm new the the rubber tire thing as well. I just got the 3 racing front wing, can't wait to try it and i'm going to do the damper tube conversion as well using team associated parts. I have the bell crank conversion using the 1.5 ackerman setup. Can't wait for my next trip to CA so i can do some real tuning now that i have setup tools for this car.
