Autocross onboard video of 03 coupe
SCCA Buccaneer Region Round 3
This is mine, 03 G35 coupe on street tires, running STU class. I took 1st in class and 11th overall out of 55 drivers

I'm used to the stock tire size and running Dunlop Direzza Z1 Star spec, but this time I decided to borrow my brother's rear wheel, and rolling on Kuhmo Ecsta MX.
I love Z1 star spec, possibly the best street tire out there, I even like it more than Bridgestone RE01R. Anyway, I gave the Kumho MX a try and compete in STU class instead (275 width rear). Since its a mismatch stagger setup, the transition thru the slalom is slower than before when I ran 245 width tire, the car understeer more in the tight stuff but it holds a better line through some sweeper and lane change gates.
One thing I noticed is even with the 275 width rear, it didn't improve my exit as much as I expected, and the MX required a bit longer warm up time than Z1 star spec and Azenis RT615 that I'm used to. And one disadvantage of MX is it has a softer sidewall, I really don't like it that much. The car feel "washy" from side to side weight transfer.
Anyway, enjoy the video!
