This hard-type graphite molded rear hub carrier is produced for the optional RTC (rear toe control) fitment on the BD8 2018 chassis. It functions as an RC-scale replacement or hop-up part, delivering a firmer mounting point where the RTC assembly governs rear toe adjustments.
Relative to softer resin knuckles, this carrier reduces compliance at the hub, which can make rear toe react more quickly under load and during directional transitions. Factor this change into your tuning alongside anti-roll bars, damper settings, and toe-in when refining handling on 1/10 on-road cars.
Installation is straightforward for those familiar with BD8 maintenance: the carrier replaces the stock RTC-compatible rear knuckle and reuses the chassis' existing hub bolts and bearings. Check fitment, endplay, and rear toe symmetry after assembly before running the car.
