Although the gross weight of the CS is not that difference from the Competition, they shaved off mass from the just the right places, to make a perceptible difference in feel and performance.
It wasn't that difficult and they didn't even have to go back to the drawing board and engineer it from scratch, except to look at data charts and compare, contrast, mix and match specifications.
For instance, the Competition 788M wheels are 4.5lbs different per wheel and it's brake rotors difference is; 8.75lbs per side for CCB.
15lbs average reduction per corner, on the hub, plus the tuning for the Adaptive Suspension is going to make the CS feel much lighter on its feet and more playful and confident in manipulating high G-Force turns than the Competition.
It's easy to, as the kids here say to; "armchair review" a vehicle they never drove before and give a presupposition on it, however, me, rationally, trust that the folks that put this vehicle together are well versed in dynamics and know they have a high bar to achieve in the Court Of Public Opinion, so it's going to be exhilarating little machine.
