Porsche 718 Cayman GT4RS Track Build

The 2024 Porsche GT4RS is already a capable track car right from the factory, but if there’s one thing we believe here at TBR, it’s that there is always room for improvement. We know that taking any car out on a race track is a risky and dangerous hobby, but we love doing it, and encourage our customers to drive their cars the way they’re meant to be driven. With that, most high-end “track-ready” cars are not equipped with all the safety measures and chassis tuning required for a proper track day.

This new 718 Cayman GT4RS was purchased with the full intention of putting in some proper track time—and that’s where we come in.

This customer wanted to install a half-cage harness bar and a pair of Schroth racing harnesses. We worked with BBI Autosport, notorious in the Porsche world for their build quality and product integrity, to source one of their harness bars made specifically for the GT4RS. The installation required cutting into and routing portions of the cage through interior panels, trim pieces, and carpet. The stakes were high, but our expert technicians made sure everything was done precisely and finished as it would have been done in the factory. With the new harness bar installed, the car will feel more responsive on the track, in addition to adding some on-track safety features.

In addition to the cage and harnesses, we installed a camber adjustment kit from Tarett Engineering to dial in the perfect track alignment. In the end, the customer was very pleased with the installation time and the fit and finish of the new track components.
