This year’s Pro class featured the most interesting and diverse field to date with competitors from as far as Scotland and USA.
International competitors got a taste of Australia’s extreme weather with the scorching heat pushing many teams to a breaking point.
One of the early casualties was Andy Forrest’s Subaru. Representing Scotland, Andy dialled in some serious times during testing until his transmission gave out.
Notaras Motorsport debuted their brand new car with Jack Le Brocq behind the wheel. With very limited testing before the event the car was plagued with mechanical issues.
Insight Motorsport’s Astra also suffered from a mechanical failure retiring with a time of 1:38.342.
LYFE Motorsport represented USA with their brand new R35 GTR. Many saw this car as a serious podium threat, unfortunately a melted piston nearly ruled them out on Friday.
A sleepless night spent fitting a donated engine meant they could return in the morning with a running car and post a respectable 1:32.405 with a close to stock engine.
SVA Imports’ Evo VI proved it can mix it with the best in the world. Gareth Lloyd managed to set a 1:29.928 on low boost before a fire within the engine cut their competition short.
Dominator Evo stepped up from Pro Am this year with Steve Glenney behind the wheel.
They finished in 5th spot and managed to shave 2.5 seconds off their previous best with a 1:29.223 lap time.
RP 968 was a brand new entry for 2015. The build was completed only days before WTAC and its first time on the track was during testing on Thursday.
It was evident that the car needed a lot of testing and refining but there is no denying its potential. With David Wall behind the wheel RP 968 kept improving throughout the weekend and finished the event in 4th place with a time of 1:26.80.
Under Suzuki had more than a fair share of problems this year. With a new aero and a more powerful engine the car looked ready to take on the reigning champ.
Unfortunately things didn’t go according to plan for Suzuki. After suffering engine problems on Thursday and eventually blowing it by Friday afternoon, Suzuki’s team worked through the night to install a spare and had the car ready for maximum attack on Saturday.
Alas it was not to be. The spare engine only lasted one lap before giving out on Saturday afternoon. Suzuki eventually threw in the towel with his last quick lap of 1:25.8476 keeping him on the podium in 3rd place.
MCA Suspension spent the months leading up to WTAC crafting a brand new, full carbon S13.
Even though they only managed one quick shakedown before the event, their efforts paid off with Shane Van Gisbergen pushing hard and claiming 2nd place with a 1:25.371.
One of the most experienced time attack teams, Tilton Interiors came into the competition with a well prepared and refined car.
With plenty of testing and development before the event, the reigning champions didn’t want to leave anything to chance.
When the weather cooled down late on Saturday, Garth made a break for it in the last session before the Superlap Shootout. Stringing his best lap together, he recorded a 1:23.777 taking his third consecutive WTAC title and setting a new tin top record at SMSP.
A well deserved win for a team that has worked its way up through the ranks and, once at the top, proved through their determination and professionalism to be great ambassadors of time attack around the world.
