The B8-RTC-14 is a hard rear hub carrier produced from graphite-molded resin for the BD8 2018 chassis equipped with the optional RTC rear toe control. It is offered as an aftermarket hop-up to provide a firmer hub mounting location than softer resin alternatives.
By reducing hub compliance, this carrier can cause toe to respond more rapidly under load and in direction changes, which in turn influences corner entry and mid-corner behaviour. When installing this part consider complementary setup changes to anti-roll bars, damper settings and toe adjustments to fine tune handling.
Installation is direct for those familiar with BD8 maintenance: swap the stock RTC-compatible rear knuckle for this carrier and reuse the chassis' standard hub bolts and bearings. After fitting, check for correct clearance, bearing play and balanced rear toe before full running.
