May as well just get the M2 Comp then. You'll be giving up looks and some niceties, and probably paying more, but you will gain sharper handling and a more playful feel so it's got some benefits.
M2's front end is stiffer/sharper for sure, so the steering response feels more lively, despite BMW's dead feel in the EPS. The M2 is also a little more "live" when pushed hard, whereas the Supra starts telegraphing info much like BMW's M-sport (ie, M40i, etc) suspensions. Stiffness or not, the behaviors give the cars distinct feels.
The front end feel is unique to the M2 Competition model. The suspension was unchanged from the regular M2, but the competition got the heavier S55 engine and the big carbon fiber front brace from the M4. That made a big difference in dialing up the sharpness of the front end.
I would be curious how the Supra responds to strut tower bracing. They don't even use the bracing that the Z4 has, and the mount holes are there and ready for use. Tada said they liked the handling better without the braces, which suggests there is some allowable chassis flex built into the Supra's feel.
