Race-Ready Balance with the XRAY 303721 Brass Holder

The XRAY 303721 Brass Rear Lower Suspension Holder adds purposeful mass to the rear bulkhead to improve traction behaviour and handling balance. It is a straightforward upgrade for competitive setups.

Benefits of the Heavier Brass Component

Compared with aluminium, this brass holder provides more weight so you can meet minimum mass requirements without stiffening the chassis. The added weight lowers the centre of gravity and helps the car stay composed through corners.

Tuning Tricks for Varying Grip

Fit it at the front to reduce traction roll on very grippy surfaces, or mount it at the rear to boost rotation and steering on medium-traction layouts. Use it as part of incremental setup changes to dial in balance.
Remark :
Due to limited stock availability, please notice that some XRAY 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.

Will this change my car's corner exit?

Yes, the extra rear weight can improve corner exit by increasing traction and encouraging rotation, which helps with drive out of slower turns on medium-traction surfaces.

Can I run this with stock electronics?

Electronics are unaffected by the holder itself. Just check clearance around the bulkhead area and secure wiring after fitting the brass part.

What is a quick way to compare setups?

Swap the brass holder front to back and run a couple of consistent laps in each position, then note differences in rotation and steering to find your preferred balance.
