also i have been wondering about diffs and whatnot... i know that a 1 way front diff is better for drifting however does not allow for the front wheels to break which in turn for a grip car is semi bad unless you know how to control your braking coming into a corner which will in time be faster since you can get on the throttle earlier in the turn and carry your speed throughout.... so that is a must for me... but what about these solid axles? what is the difference?
