Let's face it, the offset on the ND Miata is seriously dreadful to look at. Let's restore the flush look that the exterior design team at Mazda had in mind... Since your factory wheel studs aren't long enough to accommodate the extra thickness of the spacer, each kit includes 4x spacers and ARP extended wheel studs. 

Sizes:

• 15mm for factory tire size
• 10mm to allow clearance for a wider tire on the stock wheel
