be sure you use IF112C bulkheads (very important!) , use IS107 pinion and IS102 ring gear , use only the oem kyosho bearings as they dont have all the slop as some aftermarket bearings , shim so there is just an ever so slight amount of backlash when new and all the way bolted up so the bulkhead has all the tension it is going to have as it would when it is running , adjust the brakes so they dont actually lock up but effectively stop the vehicle , run for approx 15min then reshim diff
tip: put one .2mm shim behind the pinion gear
