Team Associated ASC4644 Side Springs 5.63 lb/in

The Team Associated ASC4644 side springs are 5.63 lb/in rate springs for the side spring suspension used on Associated 1:12 scale pan cars. Side springs control chassis roll, setting how quickly weight transfers onto the outside tires and how far the chassis twists through a corner, which makes side spring rate the primary adjustment for overall balance and mid corner grip on a modern pan car.

At 5.63 lb/in this is a stiffer rate in the range, typically run when grip is high and you want to limit roll, hold the chassis flatter, and get a sharper, more responsive change of direction.

Fitment covers the RC12R5.1, RC12R5.2, and RC10R5.1 chassis. They install as direct replacements for the side springs supplied on those cars, dropping into the standard spring locations with no modification. Springs take a set with use and lose rate, so fresh ones keep the car reacting predictably. Most racers carry a spread of rates so they can follow the track as it comes in.
