To begin with I have already searched on this topic. The belief is that 15x9 wheels wont fit on stock springs assuming around a 30 offset. In my case I want to run 15x9 Jongbloeds which are 36 offset. But because my car is on tokicos with flyin miata springs is this still true. Is the diameter of the shock lesser (it looks that way)? Does anybody have any experience on this topic. Thanks and the car is NA so Im aware that I will have to do some fender rolling.

Cheers, Nic

 

Ask FM what their spring diameter is. If 2.5in or less you should be fine.

 

Darn FM springs are stock diameter so no clearance. I guess 15x8 will work for my current a little over stock whp

 

I have Tokicos and FM Srings and 15x9 6ULs. Are you worried about front or rear fitment? I can possibly swap some wheels around the next few days if weather clears up and check fitment.

 

OEM diameter springs on the NA/NB will rub on a 15x9 at +36. Any spring that's smaller diameter will clear. Spacers allow that size wheel with stock springs. When we developed that fitment back in 2008, we made the decision to pull the wheel in top reduce scrub radius and aero drag. Our reasoning was that
most owners that need a 15x9 will have some sort of coilover. So the conflict doesn't often come up.
