One of Sutcliff's comments was that the ZR1 handles so much better than the Z06 as it uses completely different suspension. Does it?

The ZR1 is not built on the same aluminum-intensive chassis as the Corvette Z06 but features similar independent SLA front and rear suspensions, with aluminum upper and lower control arms. Where the ZR1 differs is the suspension tuning, which was optimized for the car’s steamroller-wide front and rear tires.
Magnetic Selective Ride Control is standard and tuned specifically for the ZR1. The system’s ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.
From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.
“The ZR1 corners better than the Z06, but has ride compliance more like the base coupe,” said Tadge Juechter, Corvette chief engineer. “Every element from the stabilizer-bar diameters to the composition of the tires was carefully matched to deliver a balanced driving experience – it’s a supercar that doesn’t sacrifice ride quality for performance.”
The ZR1 retains the 105.7-inch (2,686-mm) wheelbase of other Corvette models, as well as the short-long arm suspension and transverse spring design, but it rides on all-new, wider wheels and tires, stops with carbon-ceramic brakes and features specific spring and stabilizer bar rates – the largest-diameter stabilizer bars available on a Corvette. Also, the axle half-shafts are angled more horizontally to align with the different geometry created by the ZR1’s larger-diameter and wider rear wheels.
Magnetic Selective Ride Control (MSRC) is standard and tuned specifically for the ZR1. It is a real-time damping system that replaces conventional mechanical-valve shocks with electronically controlled shocks filled with a synthetic fluid containing minute iron particles. Under the presence of magnetic charge, the iron particles align to provide damping resistance almost instantly.
MSRC “reads” the road in 1-milisecond intervals (a thousand times per second), making it the world’s fastest-reacting damping system. Its ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.
“The damping control of MSRC allowed for front and rear springs that have a slightly lower rate than the Z06, which enhances the car’s ride quality,” said Juechter.

When you want the facts, you can rely on Bauer Millett :-)

Did he? Can't be bothered to watch the vid again but I thought that he said 'much more sophisticated dampers...'.

Not sure if I would want to buy the ex demo car from Luton?
But it is the only offical car i have seen on the road...

Everything I've read suggests the chassis is exactly the same "aluminum" chassis as the Z06?
It's certainly not the slightly heavier steel C6 one...

Indeed, and according to GM's own web-site: "Aluminum Frame with Magnesium Roof Structure and Engine Cradle". Sounds just like a Z06 to me...

"The ZR1 has an aluminum structure for optimum stiffness and low mass. It is the same structure used on the Z06, but with specific body panels and drivetrain components mounted to it.

The chassis is constructed with perimeter rails made of strong, single-piece hydroformed aluminum members featuring cast suspension nodes. Other castings, stampings and extrusions are combined into the structure with state-of-the-art manufacturing technologies. Advanced structural composites featuring carbon-fiber are bonded to the aluminum structure. The passenger compartment floors, for example, combine carbon-fiber skins with an ultra-lightweight balsa wood core.

Like the Z06, the ZR1 has a magnesium cradle that serves as the attachment point for the engine and some front suspension components, with the new LS9 engine sitting slightly lower in the chassis than the Z06's LS7 engine. Magnesium is lighter than aluminum yet incredibly strong. The magnesium cradle helps improve the front-to-rear weight distribution, as do the carbon-fiber front fenders, hood and wheelhouses.

To optimize the weight balance, the battery is located in the rear cargo area, behind the right rear wheel."

Looks like Fred Flintstone stamped his foot through the balsa wood floor in that one! biggrin
