i tested out my car today. the 19 turn provides enough power for me right now, it seems to be geared pretty well with a 27 tooth pinion. i have 40 weight oil all around, with three hole pistons, green springs front and reds in the rear. installed a rear swaybar and rebuilt the diffs, which were tight as balls when i got the car. there were actually grooves where the diff balls rolled. i will need to play around with the diff settings as i am not used to the car yet, but right now i can already tell they need to be tightened. i have a standard spektrum servo in it right now, slow as hell but it turns the tires. i have what looks like step pins on it now, which is good for bashing but probably no good for track use. what do you all recommend for a good all around track tire?
