This hard-type rear hub carrier uses graphite-molded resin and is intended for use with the optional RTC (rear toe control) system on the BD8 2018 chassis. As an aftermarket replacement or hop-up, it gives a firmer mount where toe is managed by the RTC assembly.
Compared to more compliant resin knuckles, the B8-RTC-14 lowers hub compliance and can make toe reaction quicker under load and during quick direction changes. When adjusting handling, review swaybar, damper and toe settings together for best results.
Fitting the carrier is straightforward for BD8 users: it replaces the stock RTC-compatible rear knuckle and requires the existing wheel hub hardware and bearings. After installation check for correct fit, minimal play and symmetrical rear toe.
