Converting a GT500 to KR spec involves adding dampers with firmer rebound valving, stiffer spring rates, an alignment with more negative camber (1.4 degrees versus the GT500's 0.75) and zero toe-in. Really making the KR live up to its name, though, are forged 18-in. wheels shod with sticky Goodyear Eagle F1 Supercar tires that have a 180-treadwear rating rather than the conventional 220 on the GT500. The suspension tuning, combined with recalibrated traction control and ABS, works wonders. Where the GT500 feels slow and heavy mid-corner, the KR dares the driver to go faster. Tremendous grip is provided, and putting the 540 horsepower to the ground isn't difficult. Preliminary testing from Ford indicates the KR will achieve 1.0g on a skidpad and over 70 mph in our slalom. These are some outstanding performance numbers that we'll verify shortly. Acceleration is improved by the tires as well as an increase in horsepower. The addition of a specialized cold-air intake, stainless-steel exhaust, increased spark advance and the requirement of premium fuel help squeeze an extra 40 ponies and 10 lb.-ft. of torque out of SVT's hand-built supercharged 5.4-liter V-8. And it feels even more powerful, thanks to the addition of a lower 3.73:1 (3.31:1 on the GT500) final-drive ratio. Around Miller Motorsports Park in Utah, the KR easily rockets down the straights to its 6250 rev limiter, at which point the SVT shift light illuminates. Flick the short-shift gear lever into 5th gear and the KR roars to a 155-mph electronically limited top speed. Hauling the car down to appropriate cornering speed is easy with the big brakes and sticky tires. The retuned ABS and traction control are rarely invoked. For the KR owner who wants to track his car, a brake duct kit is included in the trunk that consists of the necessary hoses and shrouds. On the track, the KR rewards cornering with a nice smooth steering input while gently trail-braking, then rolling back into the throttle. Not expecting the KR to have so much grip, I found myself having to get on the throttle early. A flying lap in the KR isn't slow in the corners and fast on the straights, it's fast everywhere. In typical Ford fashion the KR underwent a 12-hour track durability test, where the only things replaced were tires, brakes and fuel.
