Hi guys,
Just experimented on tightening my front diff on the the TT-01. Instead of using nitro tubing I simply took one of the small leftover rubber O-rings that were used to keep the side mirrors and spoiler in place (they fit perfectly!!

). One I spin one of the front wheels, all the wheel turn, the only way I could get the other front wheel to spin in the opposite direction was to hold the rear wheels really tightly.
Test Drive:
Ok, well the first thing: much more control than before (I drift ABS), I usually spun out around in the other direction as soon as I began to counter-steer too much. Right now, I can definitely feel more control and counter-steering is no longer an issue. However, I'm still wondering if I should just lock the front diff completely.
What do you guys prefer? Tightening your diff or locking it completely?
