Reality is even at normal speeds the car that will corner better at high speeds will be easier to drive quickly as the entire package will not be working as hard Additionally the total spread of weight & weight distribution is not like plumping a 154lbs on the front of the M30 to show it would handle differently as you can't get one that way.
FWIW we have loads of two lane Moonshine roads along with the The Dragon (a.k.a Tail of the Dragon ®) is famous for it's 318 curves in 11 miles; it's America's number one motorcycle and sports car road. The Cherohala Skyway, designated a National Scenic Byway, is essentially a supersized version of the Dragon. Together they make a loop through the Great Smokey Mountains.
Weights by track scales as tested by Car & Driver.
BMW Z4 30i
Brakes 0-70 146ft (-2ft)
Skidpad 1.00G (+02G)
Weight 3470lbs (-65lbs)
Front 50.9 Rear 49.5 (-47lbs)
BMW Z4 M40i
Brakes 0-70 148ft
Skidpad 1.02G
Weight 3535lbs
Front 51.3 Rear 48.7
Using the 2323 numbers off the BMW web site for the cars M40 spec sheet the spread of 229lbs would be suspect as the S30 lost weight from the C&D test car while the M40 gained weight.
We don't know specifically how these weights are generated so its best to use a common test that weighs all the cars the same way.
Bring it to the track & put them on a scale as tested to get an apples to apples comparison.
NOTE: SavageGeese put an S30 on a corner weight scale & got 3392lbs for it along with different F/R weight ratios. Think this proves the point about common testing for weigh comparisons.
