Product Insights

The SPL Front Caster/Thrust/Tension rods are a showcase of the power of precision engineering. They offer an extensive range of front caster adjustment, enabling precise alignment for an optimal turn-in response. This adjustability is essential for compensating for variances between left and right caster. Moreover, any alterations to front camber will require adjustable arms for a proper alignment which is essential on track.

These arms come equipped with low-friction, smooth articulating FK Spherical Bearings. These replace the stock rubber bushing, providing a more responsive steering feel. The anti-dive geometry can be fine-tuned using our 6061 aluminium spacers. These arms are designed to be compatible with the OEM or OEM style front lower control arms.
