I usually reduce the servo EPA to way less than full throw on steering both left and right, then turn the wheel on the transmitter all the way and increase the EPA right until the wheels hit maximum throw. Then bring them back a few degrees from max. Seems to work for me.

I recently had a problem in my 8T 2.0 blowing the throttle servo over and over. One race day I lost 2 in the same day. The epa was good but the servo was hitting the lip on the mud guard causing it to slam and eventually go out. I shaved the mud guard and so far a practice day and a race day on it with out any problems. Check to make sure that the servo case has plenty of clearance as these chassis do flex. Also make sure the throttle linkage is not binding. You should be able to move the card all the way open with the servo not moving by pulling on the end of it. If the action does not feel smooth then adjust where the ball cup is so that the arm is level and works smoothly.

Agreed. That's what I've done and I've never had any major servo problems. The maximum angle on my steering is actually an EPA that exceeds what my radio considers 100%. Seems odd, but it works.
