15x8.25 ET20 NA fitment

  1. My model of MX-5 is: NA
  2. I’m looking for technical help or recommendations on: title

Hi everyone, as per title, will the above fit an NA with standard arches, or is work required?
Tyres are 195/50/15.


I recently tried 20mm spaces on my 7J et37 wheels using the same tyres as you, giving a total poke of about 7.8 inches and they rubbed. However, my car is lowered fairly aggressively.

I think the rule of thumb is anything over 8J will require arch work. Although this is not always the case given offset etc.

If you are able to try before you buy, I would recommend doing that.
