He's got more camber than you do

To win, you must first finish.
The red car above is not damaged, it was designed intentionally to
operate with extreme camber. You can see the adjustment points
for the front suspension members.
It is powered by a Mercury outboard engine and can generate in
excess of 1.3G cornering. It was raced by a 91 yr old in this
configuration at Goodwood FoS.
The owner helped ZAD in 1957 by providing timing and scoring for
the Corvette SS at Sebring.

modern corner carver, active camber control
http://www.pistonheads.com/shows/tok...p?storyId=3093
Like a number of other manufacturers, Mercedes is researching the viability of a new system that varies the camber angle on the outer wheels between 0 and 20 degrees, depending on the road situation. Used in conjunction with newly-developed tyres, the Mercedes implementation provides 30 percent more lateral stability than a conventional system with a fixed camber setting and standard tyres.
Active camber control boosts the research vehicle's maximum lateral acceleration to 1.28 g, meaning that the concept study outperforms current sports cars by some 28 percent.

William F. Milliken, the guy who co-wrote "Race Car Vehicle Dynamics"
with his son, Doug.
Is the same guy who designed and oversaw the construction of the
MX-1 shown in the photo earlier and below.
MX-1 was inspired by a conversation with Colin Chapman and Lawrence
Pomeroy about the ideal location of the center of gravity for a racing
car. Fabrication was a collaborative effort of a team of workers paid
by Milliken, including many employees from Cornell Aeronautical Labratory,
who worked on the project after hours contributing their expertise.
Among many interesting details about the car, MX-1 spent two weeks
on a Chevrolet 4 Post Test Rig, far exceeding 'the normal K&C testing
for a prototype passenger car'

There is a illustration of the MB F400 in Milliken's book and the caption
reads in part
Fig 23-51
'Mercedes-Benz F400 Carving of 2001, a show car with active
camber on outside wheels and wide asymmetrical tires. This complex
vehicle failed to equal MX-1's cornering performance and aerodynamic
drag reduction.'
A separate drawing illustrates'Mercedes-Benz F400 Carving of 2001, a show car with active
camber on outside wheels and wide asymmetrical tires. This complex
vehicle failed to equal MX-1's cornering performance and aerodynamic
drag reduction.'
'the reduction in frontal area (hence aerodynamic drag) for a camber car
[MX-1] with narrow tires, compared with the use of vertical wide tires [F400].
Same track for both vehicles.'

Wow! How impressive the engineering!

Common sense would dictate that you can't run anywhere near that degree of camber with wider tires. Those are quite narrow and rounded. Although I guess I'm stating the obvious.

Looks like they custom built the tyres ( tires 
) for it.
) for it.
Asymmetrical Tyres
The active camber control in the F 400 Carving also paves the way for an equally new asymmetrical-tread tyre concept. When the two-seater car is cornering, the outer wheels tilt inwards, leaving only the inner area of these tyres in contact with the road. This area of the tread is slightly rounded off. Meanwhile both the tread pattern and the rubber blend have been specially selected to ensure highly dynamic and extremely safe cornering. When driving straight ahead, however, it is the outer areas of the tyres that are in contact with the road. These areas have a tried-and-tested car tread pattern, offering excellent high-speed and low-noise performance. Two different concepts can be combined thanks to the active camber control.
The F 400 Carving is something of a mobile research laboratory for the Stuttgart-based automotive engineers. They will be using it to investigate the further potential of this new chassis technology: besides offering excellent directional stability during cornering, the new technology ensures a much higher level of active safety in the event of an emergency. By way of example, if there is a risk of skidding, the wheel camber is increased by an appropriate degree. The resultant gain in lateral stability significantly enhances the effect of the Electronic Stability Program. If the research car needs to be braked in an emergency, all four of its wheels can be tilted in next to no time, thus shortening the stopping distance from 100 km/h by a good five metres.
