OK heres what i did: First i almost completly locked the diff. i used the Paper Clutch LSD mod somebody did a little farther down the page, you can use any method you want as long as you are getting 50% of the power to each wheel.Second i cut the little black thing off the motor (thats where i got most of the speed).Third i put the hard springs on the back and stock springs on the front with two coils cut off.The springs are just the ones i used because i love to DRAG

you can use any spring setup you want.And if you want to know about my driveshaft guaranteed not to fry your electronics just ask, oh yeh and its free!!
