Upgrade your F113 chassis with the 3Racing F113-307 Side Spring Set, engineered to refine suspension balance and give drivers more control on technical circuits. This kit suits racers who need repeatable tuning and finer handling adjustments during setup sessions.
The 3Racing side springs match the F113 suspension geometry to let you alter roll characteristics and weight transfer. Small spring adjustments can reduce understeer and sharpen turn-in on tight corners.
Manufactured to deliver steady spring response over multiple runs, these side springs help preserve predictable handling so lap-to-lap setup changes remain meaningful.
