Short Course PR Racing SC-201 Rear Armature 4 Degrees RR

Original replacement part for the "hanger" or rear frame, made of aluminum and CNC machined, valid for the PR-Racing SC201 chassis.

This part is identical to the original one mounted on the PR-Racing SC201 chassis.

This part is mounted in the RR (Rear rear) position and is the rear support that holds the lower suspension axles of the rear axle of the SC-201 chassis.

This aluminum piece is responsible for giving 4 degrees of convergence to the rear axle wheels, and in turn it also takes care of the roll center.

What are the advantages of this aluminum part for the SC-201 chassis?

The first major advantage of this part is its robustness. Being made of aluminum, this part offers exceptional strength. The long rear wishbones of the Short Course chassis exert a lot of force, a significant "leverage effect," so any direct impact on the rear wheels or a hard landing transmits the shock directly to this support through the suspension axles.

Therefore, since it is a metal piece, well attached to the chassis, it will be very difficult for the suspension axles to come out of their housing.

On the other hand, in addition to robustness, this rear "hanger" gives us 4 degrees of convergence in the rear axle.

Rear wheel toe-in will slightly reduce straight-line speed, but on the other hand, it will make our chassis much more stable under braking and when accelerating out of corners. Our chassis will tend towards understeer. For a rear-wheel-drive vehicle that will also be used on dirt, with jumps and bumps, rear wheel toe-in is essential.
