Precision 7075 T6 Upgrade for the RX8

For tuners wanting to tighten up their Xray RX8, the Arrowmax AM-RX8-342030 upper arm holder is a direct upgrade that boosts strength without heavy weight gain. Crafted from 7075 T6 aluminium, the component improves suspension rigidity for cleaner input response on track.

Strength and Weight Balance of 7075 T6

Hobbyists choose aluminium parts for a sensible compromise between toughness and mass. The 7075 T6 grade resists bending under load, helping the suspension keep its intended geometry in competitive running. The outcome is a durable, lightweight chassis detail that supports repeatable handling.

Features and Fit

  • Material: 7075 T6 aluminium for superior rigidity
  • Design: Light profile to lower unsprung mass
  • Compatibility: Built specifically for Xray RX8 platforms
  • Performance: Stiffer mount points for steadier cornering

Is fitting straightforward for standard RX8 chassis?

Yes, the part is designed to align with stock RX8 mounting bosses and will bolt in on standard chassis configurations.

Can this improve lap times?

By reducing flex at the upper arm anchor point, you can get crisper steering and more predictable handling, which may help consistency on the lap.

Is aluminium maintenance different from plastic?

Aluminium requires basic checks for cracks and secure fasteners; it does not fatigue the same way plastic can, but look for impact damage after heavy hits.

Are shims or spacers needed after fitting?

Most installs keep existing shim stacks, though minor adjustments can be used to fine tune toe and camber if the new holder alters geometry slightly.
