Tune Corner Exit with XRAY 345858-G

Targeted at hobbyists who chase lap time gains, the XRAY 345858-G Graphite 18T Low-Friction Front Belt Pulley brings precise engineering to the RX8E 2023 front drive. The graphite composite is chosen to balance durability with reduced mass for better on-track behaviour.

Why Graphite Works Here

The composite lowers contact friction and reduces the rotating inertia in the front belt run. That helps the car pick up speed earlier out of turns and improves transient throttle control during direction changes.

Compatibility and Parts

The pulley is produced to fit the RX8E 2023 centre shaft assembly without need for adapters. It is sold separately from the composite cover; the matching cover set is available as part number #345800-G if you want a full assembly replacement.
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 I use this pulley with aftermarket belts?

Most standard front drive belts that match the RX8E 2023 tooth profile will work, but check belt width and tooth pitch before fitting.

Will graphite affect wear on the belt?

Graphite reduces friction so belt wear can decrease, but regular inspection for glazing or edge wear is still recommended.

Any setup tips after installation?

After fitting, check belt tension and alignment on the centre shaft and run a few low speed laps to confirm smooth engagement before full throttle sessions.
