Stability Gains from Longer Rear Arms

The XRAY 303174-H Rear Suspension Arm Long Left is intended to sharpen handling on the T4 2020 platform. With a 7mm increase over short arms, it improves front-end grip in low traction and adds composure when grip levels rise, aiding consistent lap times.

Durable Composite with Anti-Roll Mount

Produced from a dedicated hard composite, this arm combines strength with a degree of flex that enhances traction. The anti-roll bar mount is built in, and because the composite is slightly less stiff than graphite, it can provide better traction on very-low to low grip tracks.

Installation and Centre of Gravity Tips

Designed for T4 2020 Specs (300026, 300027), the XRAY 303174-H lets drivers explore standard shock locations or a lower 4mm position for a lower centre of gravity. The lower option needs the optional lower ULP shock tower and helps stabilise the car through tight corners.
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.

Can this arm be used for club racing events?

Absolutely, it is suited to club and competitive racing when you need more front traction or a steadier rear end depending on track conditions.

Will using the longer arm change roll characteristics?

Yes, the longer arm alters roll distribution and can reduce oversteer on corner exit, particularly when paired with the correct shock setup.

How do I maintain the arm for long service life?

Regularly clean pivot areas and check for play at mounting points; replace the arm if you spot cracks or excessive wear to avoid setup drift.

Is setup advice available for switching to the 4mm lower shock mount?

Lowering the shock mount lowers the roll centre and usually requires softer damping or revised camber to retain balance; test in small steps to find the right compromise.
