Yes, reportedly: The higher-offset 15x8 sits further inboard than a +25/+28, which makes it one of the easier wide wheels to fit on an NA.

Details
The higher-offset 15x8 sits further inboard than a +25/+28, which makes it one of the easier wide wheels to fit on an NA. The 6UL's original 15x8 was +36; the 2026 Gen6 version is +34, so check which you are buying. An old SuperMiata fitment table (quoted on a turbo-Miata forum) says 195/45 through 225/45 tires fit with standard-length dampers without rubbing; 225/45 may need the liner trimmed with short-body coilovers that allow more bump travel, 225/50 needs liner trimming and a fender roll on an NA, and at least -1.25 degrees of front camber is suggested for 225/45 on an NA. A UK owner calls 15x8 +36 about the biggest an NA takes 'without surgery'. The maker says the Gen6 wheel clears NB Sport brakes and its own 11-inch big brake kit.
