Hi you need a shorter chassis , not as short as the buggy , Mentality 1 on LSD is the man for a chassis need the motor back as far as you can run axle as the rear tailshaft , a alloy rear diff housing as the pinion bearings will melt out the std one , a centre diff locker team chase i think i have soft cush drive in it , pipe to suit centralise and balance the chassis out with the servos and tank , body is easy to mod to suit but you need to get the weight out of it as there pretty heavy and right near the limit , all the measurements are in the AARCMCC rules , fastest 2wd at the Nats was one of these Chris Pattersons , Out handle a Baja once set up and still tough
