Leh Keen Proves the GT2 RS’ Potential With a New Record Lap

Earlier this year, we saw David Donohue wheel the latest GT2 RS around Road America in a sizzling time of 2:15.17 on Michelin Pilot Sport Cup 2 R tires. Last week, IMSA ace and all-around hooligan Leh Keen took another GT2 RS around the four-mile circuit in Elkhart Lake, Wisconsin, and slashed the previous record by a considerable margin.

 

Granted, the comparison isn’t exactly fair. While Donohue’s car was a bone-stock GT2 RS—though likely one of the best of the batch, Keen’s car received a few tweaks to get a little more out of the widely adjustable chassis. Aside from the factory cage and the Manthey water tank for longer fast laps at full power, there are two major changes. This RS benefits from a more aggressive alignment courtesy of 311RS, who’ve modified a few track-spec cars featured on this site, as well as a engine tune from Mitch McKee. The tune reaps an additional 60 wheel horsepower, total 690 at the rear wheels. Truly, this mild package simply maximizes the potential of the factory setup without bringing in many aftermarket parts. With a new set of Cup 2 R tires—likely providing the largest benefit—Keen set out to slash Donohue’s lap by a considerable margin.

And though he did, the ease with which Keen drives this car makes you wonder how. Though still slightly nervous on the brakes, the car looks so much more composed from mid-corner onwards. The corner exit acceleration is hard to fathom—it looks almost four wheel-drive at times, and only once does the break away under acceleration (2:00). When it does, it looks so comfortable and predictable that Keen’s steering inputs are more like those you’d expect from a Sunday drive than a record-breaking lap at one of the fastest road courses in North America. Even when dancing through Turn 10, it looks so casual.

At the end of his first economical lap, Keen crossed the line in 2:12.9—a time which rivals a GT3 Cup Car and bests the fastest non-Porsche production car, a Viper ACR, by seven seconds. Not only hadn’t he needed a warmup lap, he hadn’t even used tire warmers. After that, his times began to worsen, and so they packed it in after a fairly stress-free and straightforward day at the circuit. Of course, it’s never that simple; much headscratching work goes on in wee hours beforehand to get such an encouraging chassis, But it’s fair to say that the preparation this car received made setting a staggering time look easy.
