Tune Your R4 Series with the Kyosho VZW439

If you want to refine handling on R4 cars, the Kyosho VZW439 brass rear suspension holder is a straightforward upgrade. Made for the V ONE R4 Evo. and R4sII, it adds about 10g to help improve traction and on-track stability.

Why Brass Improves Rear-End Behaviour

Brass is valued in the hobby for its density and durability. The extra mass lowers the vehicle center of gravity, helping the rear end track more predictably through fast corners. That additional weight is useful for drivers chasing consistent lap times.

Fitment and Quick Installation

This Kyosho VZW439 part is machined to fit the V ONE R4 Evo. and R4sII chassis precisely, so installation is simple for most hobbyists. Whether you are trimming setup for a club meeting or dialling in a race car, the holder slots in with minimal fuss.
Remark :
Due to limited stock availability, please notice that some Kyosho 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 much does the brass holder change handling?

Adding 10g shifts balance rearward and lowers the center of gravity, which typically increases rear traction and steadies corner entry.

Will this fit other Kyosho kits?

The holder is designed specifically for the V ONE R4 Evo. and R4sII platforms; check chassis compatibility before fitting to other models.

Any tips for installing the holder?

Remove the rear suspension mounts as instructed by your manual, fit the brass holder ensuring alignment, and recheck suspension geometry after tightening.
