Making a 550bhp R faster than a p575

[V6ontheway]

I posed this question on an F Type Facebook group, and although we didnt reach a correct answer there were some interesting responses. So...

Looking at the official figures the F Type R does 0 - 60mph in 4.1 seconds. The newer F Type 575 does 0 - 60 mph in 3.5 seconds. How does it achieve this? Is it lighter, a simple remap or different internals? This brings me to the question how do I get my R to match the 575 0 - 60mph number, or beat it?

What would you do with the 0.6 seconds you saved?

Gearing (final drive and gearbox ratios), shift speed, engine mapping, ambient conditions, tyre compound, rolling resistance of tyres, pressures, weight, reaction times, fuel octane, aerodynamics, suspension, traction, road surface, 2WD/4WD, oil viscosity, wet sump, piston weight, injector sizes, spark strength, supercharger speed, supercharger volume, cylinder temperature, unsprung weight, rotational mass…some of the things which can affect acceleration…

Isn't the 4.1 second quoted figure for the RWD version? The AWD is significantly faster off the line than my car (but not nearly as fun )
