Sharper Corner Control with Yokomo B12-RTC-5L

The Yokomo B12-RTC-5L Graphite Steering Block Arm L is a precision 2.4mm graphite component made for BD12 and BD11 chassis. By moving the tie rod attachment out from the standard RTC location, this arm limits toe-in change through suspension travel so your car turns cleaner and feels more consistent on high-grip surfaces.

Track-Focused Handling Improvements

On busy race setups where consistent steering matters, this arm helps reduce unwanted toe variation during hard driving. The graphite build keeps weight down while remaining strong enough for frequent track use, helping drivers keep predictable steering response lap after lap.

Chassis Compatibility

The part fits MSR-BD11, MSR-BD12, and MSR-BD12A chassis, making it a direct upgrade for a range of Yokomo touring car platforms used on high-traction circuits.
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.

How difficult is the swap from a stock RTC arm?

Installation is straightforward for anyone comfortable with basic suspension work; remove the stock arm and fit the B12-RTC-5L using the same mounting points and hardware.

Will this change my steering feel on lower grip tracks?

On lower grip surfaces the effect is less pronounced, but you may still notice slightly different steering response due to the altered tie rod geometry.

Do I need different turnbuckles when fitting this arm?

In most cases existing turnbuckles will work. Check thread engagement and alignment after fitting and replace any worn parts to maintain precise steering geometry.
