Performance Parts and Engineering (PPE) Press Release
Triple Australian Manufacturers’ Championship title holder Stuart Kostera is beaming: “This car is so fast!” is his simple summation of the PPE-prepared Kintyre Racing (sponsored by Schaeffler Automotive Aftermarket) Audi TT RS he will share with Glyn Crimp and Matthew Cherry at the 2015 Bathurst 12 Hour.
Kostera is working the TT RS through a pre-event test at the majestic Phillip Island race circuit in Victoria, chosen for its multitude of long, fast corners that offer a similar challenge to Mount Panorama.
“We’ve come down from quite a stiff setup. The front springs are 60 per cent softer than when we started, to make the most of the [tyre] grip,” he adds.
As the day progresses, Kostera finds a groove in the low-42s, as he works to dial out some high-speed, power-on understeer. “Being predominantly a front-drive car, there’s some natural understeer when you are trying to deploy 330kW,” says Heaphy. “We have a control unit that can alter the characteristics of the Haldex system, to make it faster-reacting in distributing drive to the rear, and it’s something we will look at back in the PPE factory.”
Small, niggling items — stuff you want to find in testing, rather than mid-race — are promptly seen to by the PPE mechanics as they come to grips with the hydraulic clutch system employed in this six-speed manual TT RS. “It works beautifully, but when the fluid gets dirty, the pedal can become inconsistent,” explains lead mechanic Craig Tulloch as the crew freshens the fluid.
With an eclectic mix of competitors within Class D, the drivers, crew and car will be challenged throughout the 12 hour. But the Kintyre Racing PPE team wouldn’t have it any other way.
