I have Toyo Proxies 4 Plus all around on my '09 370Z
I'm running Toyo Proxes 4 Plus all-seasons on my '09 370:
245/35/20 on 20x8.5 TSW Tabacs front
295/30/20 on 20x10 TSW Tabacs rear

Had Nissan decided to redesign the Z completely from the ground up the way General Motors did the mid-engine C8 Corvette, they might have been able to go with a DCT--but then the Z would never have come in at the existing price point that it did.

Doesn't flow with the body lines. And My God, those HIDEOUS exaust tips and over-done duckbill spoiler...
Hycade did a much better job making their kit look like it was made for the car.
