It blew it’s own door off.

A Sydney metal fabricator is behind a big-budget Aussie assault on the World Time Attack Challenge.

Ben Creswick has built this highly-modified carbon-fibre bodied Subaru WRX, featuring a fully sequential transmission and 2.5-litre turbo-charged flat-four ‘boxer’ engine.

The Hankook Carbon WRX, piloted by a high-profile professional driver, will target the current WTAC lap record, set by driver Tarzan Yamada and Japanese team CyberEvo to win the 2010 event.
Mr Creswick says the car has been in development for five years – starting as a heavily modified street car before undergoing a transformation into a full-blown time attack racer.

“We’ve modified the chassis to get the centre of gravity really low – it’s six inches lower than a standard WRX and much wider,” said Mr. Creswick.

“The big guards and wider track also allow us to run bigger tyres than usual – 295/30ZR18 sized Hankook Ventus TD semi-slicks on both the front and rear of the car.”

Mr Creswick says the car is being developed with the aim of exceeding the 700 hp (at the wheels) and 1000 kilogram weight targets set by best Japanese and American time attack cars.
“At the time I started getting more serious with it, the U.K and U.S national champions were both 1999 model WRXs,” said Mr. Creswick, explaining his choice of vehicle.

“That generation WRX’s light weight, handling and capacity potential – you can have anything up to 2.8-litre if you want it – makes it an ideal base for a time attack car.

“And the AWD is a benefit too because, with the power output we’re expecting, I doubt you could do it with a RWD car.”

Limited testing of the Hankook Carbon WRX at Wakefield Park Raceway has seen the car set an easy 1:01.9.
