Rear Suspension Upgrade for NT1 Using XRAY 333721

The XRAY 333721 Aluminium Rear Lower 1-piece Suspension Holder is a practical upgrade for racers wanting a firmer rear mount on NT1 cars. CNC machined from Swiss 7075 T6 aluminium, it provides a stable interface that resists deformation under track stresses.

Maintain Rear Geometry Through Impacts

This holder is shaped to preserve the established NT1 geometry, offering a strong mounting point for the suspension arms. Geometry remains consistent after impacts, helping drivers rely on repeatable handling. The construction still allows arm movement that smooths traction transitions.

Expanded Adjustment for Rear Setup

By using square composite bushings from the T4 and XB4, the XRAY 333721 supports vertical hinge pin changes and pin spacing adjustments. These capabilities increase the range of roll centre and geometry settings for precise rear tuning.

Slimmer Profile for Increased Rear Grip

The reduced width of the holders brings the arms closer together, which improves rear traction. This narrower spacing is beneficial when you need added grip exiting corners and under acceleration.
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 improve corner exits?

Bringing the arms closer and stiffening the mount can enhance traction on corner exit, especially on higher grip surfaces where rear stability matters.

Are these holders compatible with stock bushings?

They are designed to work with square composite bushings similar to those used on T4 and XB4 cars. If your stock bushings differ you may need to swap them for full functionality.

Should I change other rear parts when fitting this?

Consider reviewing hinge pins and bushings when upgrading to aluminium to ensure the full range of adjustments is available and to prevent premature wear.
