Hpi Pro 4
I found i could tighten my diff more than before when i put the TC3 kit and ceramic nitride balls in. It was also way smoother than it was with the stock gear

Did I see the World Famous Erik Shauver on the results list of the Reedy Race???????????
What's up Erik? Hope all is well out there... You guys coming to Cleveland this year?
Do you guys put the put the delrin outdrives on the front diff?
If not is there a reason for this? and is it softer than the grafite 1's ie will it brake easier?

What problems do people find wrong with the stock diff nut? I've had no problems...yet? And how do i do this tc3 mod?
The HPI screw setup is designed to allow diff adjustment without popping the upper link off.
Does anyone here know a better one-way shim setup than the out of the box one they give you? I tried adding one more shim, but it totaly ate up 2 teeth in the front one-way gear, and ate one tooth on the input shaft gear.

right now I'm using Yellow and gold for asphalt w/rubber tires.

Most of the time, front springs are harder than the rear. you may try white for the front, gold for rear. It depends on your track condition what to use.
so I should place the gold rear and the yellow/black in the front?

I don't remember it was my NTC3 or the Pro 4 (which is sucks cause I service both cars at the same time and don't remember 100% which is which)....the manual said 2 shims on the 1 side for the 1 -way, I ended up using 3 shims (1 extra more then the manual said)........and I have never get stripped gear problem except 1 time my shaft cap was broken, 1 thing to the other, the whole front trans were ended up in a melted plastic.
No diff case are made the same, so yours might only need 2, but mine, I need 3....(there are no shim required on the NON DIFF GEAR side of the bearing spacing..)
thanks for the tip, hope this is true when i race today.

I run white in front with the stock silver in back.This works well on low/medium grip asphalt. I also run the spool in front with 1 degree rear anti-squat...2.5 front block and 3.0 rear.
