Team Associated ASC32057 LP Progressive Springs 14.9-17.3

The Team Associated ASC32057 LP Progressive Springs are 14.9-17.3 Lb/In low-profile shock springs for the RC10TC8 touring car. Unlike a linear spring, a progressive spring increases in rate as it compresses, staying soft over initial travel for mechanical grip and building stiffness deeper in the stroke to control roll and prevent bottoming.

Specified at L17 length with 4.5 coils and 1.3mm wire, they fit the TC8 Graphite-Spec and TC8 Steel-Spec chassis. This is the firmer of the progressive options, suiting higher-grip surfaces or a driver who wants more support under heavy cornering load without giving up compliance over smaller surface imperfections.

They install on the stock TC8 shocks with no modification, so you can test them against your existing springs in a single pit stop. Adding progressive springs to your setup box gives you a tuning tool that behaves differently from any linear rate, and often finds lap time where conventional spring changes have run out of answers.
