Brian Goodwin's (from Goodwin Racing) quote from https://forum.miata.net/vb/showthread.php?t=632222:
"15x8 is already overkill for street use....9s are for the guys really racing the weekends at track and SCCA/NASA, autocross, etc.
Doing 9s without racing is just posing and comes with downsides like high chances of curb rash, much stiffer ride with no benefit to street user as compared with same tires on 8 inch, etc."
If I was to buy now, I'd get 15x7.5 rims for DD and 15x9 rims for trackwork (currently have 6UL 15x8s with 205/50/15 tyres for DD and 16x8 225/45/15 for trackwork).
Originally I bought the 15x8s because they could fit a 205 and 225 tyre but after picking up a 2nd set of 15x8s on this forum I realised it was much simpler to have 2 sets or rims/tyres for each application.
15x7.5 rims are lighter and cheaper and will allow fitting of a 205/50/15 trye.
15x9 rims fit 225/45/15 tyres better and many claim faster times than on 15x8 rims with 225 tyres.
From behind, the 15x9s with 225/45/15s do look bitchin' for DD though but require noticeably more effort (especially in carparks with my power steering delete).
