Physics.

 

1) stiffen up the rear end (also, do some research to help select the right shock setup)
2) get some traction bars
3) solid motor mounts (or motor mount inserts at least)
4) LSD
5) sticky tires that are wide and have a tall sidewall
6) learn to be a better driver

 

Tires make the difference between an understeering nightmare and a road going dream.

 

True that.
