Garry Rogers Motorsport is ready to start production of the locally-designed and developed production components for the new S5000 category after a successful test day at Winton Raceway today.
The Victorian-based team spent the day at Winton validating the changes, with the car performing faultlessly in a rigorous workout around the hot Winton track.
The team has confirmed that this is the final production specification for the S5000, and the squad will now head back it its Dandenong base to begin mass-production of the components that have been developed to complement the Onroak-Ligier chassis, the InnoV8-modified Ford Coyote V8 engine and the Holinger six-speed sequential gearbox.
The changes that have been implemented on the prototype chassis include the locally-designed and built suspension, to incorporate upgraded brakes, and detail upgrades to the cooling system to account for even the hottest Australiasian race weekend.
The team also took the opportunity to evaluate numerous tyre options from US tyre specialists Hoosier.
Regular S5000 development driver Tim Macrow was the sole driver at the test, back-to-backing the information from the previous set-up with the new developments.
GRM currently has four other Onroak-Ligier tubs at its workshop, with the other nine ordered tubs set to arrive in late May or early June.
The next time the S5000 will be seen on track will be turning demo laps at the opening round of the Shannons Nationals at Sydney Motorsport Park, headlined by the all-new TCR Australia Series, on May 17-19.
