XRAY 340008 RX8.3 Competition Nitro Touring Kit  [XR-340008]

Developed for consistent handling and grip

The XRAY 340008 RX8.3 refines the nitro touring formula with chassis and suspension tweaks aimed at consistent lap times. It is targeted at racers who prioritise predictable balance and setup flexibility on varied track surfaces.

Chassis rework to sharpen rear grip

A key change in the RX8.3 is the slimmer chassis width that improves traction at the rear. The lower rear suspension mounts are moved 2.5mm inward to refine the rear geometry and help the car track straighter under power.

Suspension geometry and shock placement updates

The suspension has been revised using steel extension plates on the rear arms to alter shock mounting points and match the new inner pivot position. This rework enhances mid corner stability and helps the car react more predictably when changing direction. The rear shock tower and upper arm brackets were redesigned for the reduced bulkhead spacing.

Built for durability under race conditions

The RX8.3 includes a new rear solid axle shaft and a tailored composite pulley suitable for the narrow rear arrangement. Both front and rear bulkheads are updated to accept composite anti-roll bar bushings, lowering play and improving service life.

This XRAY 340008 RX8.3 kit gives racers a refined platform that balances durability with tunability. It is a strong choice for tuners and competitive hobbyists who want a chassis that responds well to setup changes.
