My SS5800 has found a permanent home in the EvoIIIs.
(shredded my brandnew TA04 belts)
Rear diff is a little tighter than normal, but no slip so far.
I run oneway up front; gear no problems when shimmed nicely
and its got the Tech 3-piece shaft - otherwise stock EvoIIISL.
Gear it a bit higher than a Monster, somewhere between a P2K
and the Monster. Its got enough torque to pull serious speed.
