Ive been running a spool in mod and the only problem that i overlooked are the stock cvd pins. i broke 6 pins in 6 runs. i bought a rayspeed cvd set (made by mip), used tc4 bones, and problem solved! my car handles great but got to try my long awaited jrxs first too see which suits me better coz i break most ofbthe time due to aggressive driving. i also got a tip on how to make a direct center pulley, just takes lessvthan 5min w a dremel and a nice thin bit, and the pulley pin. thats why theres another hole in the layshft, thars for the pin to hold the main gear in place, u need to take out one bearing though but its ok, measure the pin over the main gear adapter and mark where to dremel, then your done, now you got a center one-way and a direct diff all in one by jusr slipping in the pin.
