stroked engine (GTS) vs intake/cames (CSL)
2 seats (GTS) vs 4 (CSL)
Gutted/caged interior (GTS) vs not (CSL)
more modern tires (GTS) vs older (CSL)

Nothing about it was impressive or favorable to the image of e9x chassis imo.

As for the time posted for the F8X, it's both impressive an exactly where I'd expect it to be. Put some non street tires on it, and it'll be faster than the GTS or CSL, much less the base models.
adjustable suspension is as only as good as the adjustments

multi piston calipers aren't necessarily better for performance outright

adjustable aero/wings are only as good as the adjustments again

engine, seating, gutted + caged, tires.. all valid however lol.
