I run the car as an L car with tubes.. meaning .075" glass Tbar. No side springs.
you will find the thicker chassis is more consistant on carpet, carries a bit more corner speed...
the aluminum is beutiful... period.
the bearings are rediculous.. my car is 4 months old.. and the rear axle still will find the heavy spot on the wheels.
breaking a 1/12th scale car? uh.. nope
its pretty indestructable...
