this is the most important part of an oval setup. This sheet is like GOLD, once you learn how to read it, you will be amazed at what your car will be capable of. You realy need to get the dual stage shock pistons to get the most out of your car.

a briefe rundown on how to read this chart is:
each set of <-> arrows is for that corner of the car.
example, track bar is width of the car.
If the right side of the arrow is yellow, on the right rear, that side of the car needs to be extended out. If it was the left side of the arrow, that side of the car, (right rear) would be narrowed. I always made changes by .5mm.
JUST BECAUSE IT SAIS TO NARROW THE CAR, DO NOT DO IT ON BOTH SIDES, JUST THE SIDE THAT IT CALLS FOR.

RPM makes the two stage shock pistons part # 80430 and #80420, and they do work on the NTC3 for oval very well. (yes, they are for off-road). here is a link to where to get them:
