GeoCarbon Bumper Brace w/HD Stopper for XRAY X4 & X4F ('22/'23)

Our brand new GeoCarbon Bumper Plate w/Stopper for XRAY X4 sports a stylish, stealth and innovative design. The plastic X4 Bumper and Stopper whilst effective, in our eyes don't provide the most stylish or convenient solution to keeping your chassis safe in the event of a crash.

Our design integrates the stopper under the main bumper plate, lining up with the bearing mounts on the front bulkheads. In the event of a crash, the force will be transferred through this (which is strong due to being fitted with a bearing) and keep the chassis in tact, with minimal effect on the bulkheads. The 5mm thick heavy duty brace recesses over the small bumper posts enabling it to get low enough to align with the bulkhead. When tightening the upper plate, it clamps the whole assembly down tightly.

Upon resting, there is a 0.1-0.2mm gap between the bulkheads and this support, to prevent any rubbing and tweaking. This support will only be active in a crash! This provides the optimal solution to keeping your chassis on your brand new X4 safe, whilst looking great at the same time!

Our new Bumper Plate also features three sets of holes, allowing you to adjust the bodyshell forwards and backwards as seen on the standard plates. The integrated stopper does not move, it will be in the same place regardless of the body post position! Unlike other stoppers, ours can also stay in place when removing the front anti-roll bar, and doesn't need to move when using the front flex brace or not!

This provides you with a more stylish, more durable and more convenient solution over the standard parts.
