Haven't had a chance to run the car yet on the track...but initial testing in my front street..the is very quiet, fast, transitions extremely well, and corners very fast even with a dual diff set-up.
Other than the teflon bearings I've installed....I've also lubed the diff gears with White Lighting dry wax lubricant... I also used HPI teflon impregnated shock pistons...feel alot smoother than the stock ones.... HPI #5 is equivalent to YOK #3.
now I just gotta paint a new body for it....
