XRAY 303721 Rear Bulkhead Brass Holder for Improved Balance

The XRAY 303721 Brass Rear Lower Suspension Holder gives your car extra rear mass to stabilise handling. Made for the rear bulkhead, this brass piece is a simple upgrade for flyers who want cleaner mid-corner balance.

Weight, Balance and Handling Benefits

This brass holder is noticeably heavier than aluminium options, supplying the extra mass needed to meet weight limits while keeping chassis flex intact. By moving weight low and spread across the rear, it helps the car feel more planted and reduces nervousness on corner exit.

Setup Tips for Different Grip Levels

Placed up front it can calm traction roll on very grippy surfaces, while fitted to the rear it promotes rotation and sharper steering on medium-traction tracks. Use it as part of a stepwise tuning plan to tweak understeer and oversteer.
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.

How does adding brass change lap feel?

Adding brass increases rear-end weight, lowering the centre of gravity and improving stability. Expect smoother mid-corner balance and more predictable exits on medium traction tracks.

Will this fit my existing rear bulkhead?

This holder is made for the standard rear bulkhead fitment used by compatible XRAY kits. Check your bulkhead mounting points match the part before ordering.

Any quick setup advice when installing?

Start by testing with one brass holder at the rear, then adjust front anti-roll or shock spacing to balance rotation. Make small changes and note lap times or driver feel.
