Graphite rear link tailored to BD8 2018

This graphite molded rear hard suspension arm is intended for the optional RTC (Rear Toe Control) arrangement on BD8 2018 chassis. The component follows the BD8 2018 rear layout, featuring a 54mm in/out suspension pin spacing and a 40.5mm shock pivot.

Use this arm when you want to reduce rear hub flex and preserve toe settings under load. It replaces the OEM rear arm and pairs with RTC parts to give more precise toe adjustment without changing the remainder of the rear suspension geometry.

Tuning advice: a stiffer rear arm sharpens entry response and can aid consistency on high-traction surfaces while making the rear more responsive on loose circuits; verify shock angle and roll centre after installation and keep original mounting hardware unless the RTC kit specifies alternatives.

Compatibility

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can this arm be used on non-RTC BD8 builds?

Yes. The arm fits the BD8 2018 rear mounting points, though its benefit is greatest when used with the RTC toe control hardware.

Are there any special care steps for the graphite material?

Graphite is durable and light but inspect mounting holes and edges for wear after heavy use; avoid overtightening screws to prevent stress at the mounting points.

Will this change the shock mounting position?

The shock pivot is 40.5mm as per BD8 2018 specification, so shock angle should remain consistent; recheck geometry after fitting to confirm ride characteristics.
