Setup and Track Width Control with 3RACING 3RAC-WX125/PK

The 3RACING 5mm Wheel Adaptor, model 3RAC-WX125/PK, is a compact spacer for drivers focused on setup consistency. It allows small, repeatable changes to track width to help tune lateral load and steering balance without changing suspension geometry.

Competitive Use and Fitment

As a 5mm spacer the adaptor is suited to fine tuning on many 1/10 scale race platforms. Use it to adjust track width for tyre contact patch and to evaluate handling differences between runs while keeping the rest of your setup constant.

Installation and Service Notes

For reliable performance, install the adaptor on clean hub faces and verify wheelnut engagement. After a setup change, run short test laps and inspect mounting points for movement or wear. Document the change so you can return to baseline settings quickly.

How does a 5mm spacer affect lateral grip in competition?

A 5mm change alters scrub radius and track, which can shift load distribution across the tyre. Use controlled tests to see whether grip increases in your circuit conditions.

Should I retune toe or camber after adding the spacer?

Small track changes can interact with toe and camber; check tyre wear and steering response and make minor adjustments if lap times indicate imbalance.

Is the 3RAC-WX125/PK appropriate for testing setup changes between heats?

Yes, its simple fit makes it a handy option for quick comparison tests between heats, as long as you keep careful notes and verify clearances prior to each run.
