KR rear wing


Recommended Posts

I just read in Motortrend's write up on the KR that the rear wing is improved over ours. Anyone know any specifics on how it is better?

The new GT500KR’s handling is the result of a clever combination of chassis engineering and aerodynamic honing, proven by its 1.0g lateral acceleration skidpad capability.


"The new GT500KR handling story is all about balance," said Jamal Hameedi, chief engineer of Ford SVT.


"That’s the big result with new GT500KR dynamically," agrees Gary Patterson, Shelby Automobiles chief test driver. "Its balance makes this car very confident and predictable to drive, even on the limit."


Sharp Aero


Just as on the race track, aerodynamics has played a major role in shaping the dynamic capabilities of the 2008 GT500KR.


"Our objective was to build on the GT500 to give the new model more dynamic balance, reflecting its higher power output," said John Pfeiffer, SVT product design engineering specialist. "We focused our efforts on creating even downforce levels front and rear. That meant finding more frontal downforce than the previous model."


Extensive engineering work was devoted to deliver more front downforce, starting with the most obvious aerodynamic feature on the new car – its slick carbon-fiber front splitter.


The new splitter is an all-new profile, more aggressive than that of the GT500. It is deeper and consistently full in shape, mirroring the shape of the leading edge of the hood and bumper above it for design coherence. Its lateral edges, which kick up small aero wall shapes at the wheel arches, are a clear statement of performance intent.


The thinner splitter aids with approach angle clearance, but downforce is its primary role helping achieve a 31 percent improvement. The splitter structure creates a flat floor shape under the front portion of the bumper shape to the leading edge of the front wheels. Enclosing this area provides a significant downforce enhancement.


The splitter underside also incorporates an integral brake cooling feature, with molded shapes inspired by NACA ducts. At the rear, the new GT500KR has a less prominent spoiler, a design to balance front-to-rear downforce variances. That’s an important part of its balance and poise at speed.


"You have to experience the new KR at speed in a curve to feel the difference," Pfeiffer said. "It has an absolutely minimal aero moment of just 54 lb.-ft. at 120 mph, a 92 percent improvement versus the GT500. That is central to its confident handling ability. Because it’s just as happy at 120 as it is at 60, the GT500KR is a very special performance car."

yup, I remembered it incorrectly, thanks for the link.


Anyone considering making the change to the KR/V-6 wing?


Don't flame me for this but I always thought the GT (AKA 1969 Boss/Mach) wing is the most attractive but anyone know what downforce properties they posess?

What I've been told by people at Shelby is that the GT500 wing is too good at high speeds. It'll start lifting the nose of the car at 150+ mph.


/wanders out to the garage to remove the limiter and retune the car

Don't flame me but I have thought of putting a ducktail stle spoiler on my car.Anyone done this and have pics?I really like the way they look,But as posted earlier have no info on downforce.I would imagine that the stick on style is out :hysterical:
