XRAY 303172 Rear Arm for High-Grip Tracks

The XRAY 303172 Aluminum Rear Suspension Arm is manufactured from Swiss 7075 T6 aluminium to deliver a stiffer feel at the rear axle on high-grip layouts. Replacing the stock composite graphite arm brings crisper steering response and improved corner speed.

Why Racers Choose This Arm

Featuring a single optimised shock position, the arm helps maintain predictable balance during fast transitions. The integrated anti-roll bar attachment points reduce chassis lean and aid stability through long corners.

Compatibility and Setup Tips

This rear arm fits into common touring car rear assemblies without major modification and is available either singly or as a pair to match your setup. Small setup tweaks to droop and shock angle will help you fully exploit the aluminium arm.
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 arm make the car oversteer more?

A stiffer rear arm can change balance towards more rotation if other parts remain unchanged, so pair it with small suspension tweaks to regain neutral handling.

Is aluminium advisable for glued carpet?

Yes, the 7075 T6 alloy holds up well on glued carpet where grip is high and reduced arm flex improves lap consistency.

Should I change anti-roll bar settings?

You may need to soften the rear bar or adjust sway links to fine tune roll behaviour after fitting stiffer aluminium arms.

Does this arm require special maintenance?

Inspect mounting holes for burrs and keep pivot pins clean. Aluminium resists wear but routine checks preserve consistent performance.
