RC10B6.4 -1mm Scrub Caster and Steering Blocks (ASC91985)

A -1 mm scrub front caster and steering block set for the RC10B6.4 platform. This geometry upgrade helps fine-tune steering feel and front-end stability by altering the front wheels' scrub during turns.

Compatible with RC10B6.4, RC10B6.4D, RC10B74.2, and RC10B74.2D models, these blocks replace the front caster components in the suspension to adjust scrub and steering behavior. They’re designed for straightforward installation and deliver more predictable handling in both practice and competition driving.
