a set of four (4) spacers. 2 are 15mm thick and the other 2 are 20mm thick.

Studs are 12x1.25 good for either Nissan or Subaru. The spacers come with hubcentric collars for Nissan vehicles. But pop that out you can throw them only 05+ Impreza STi and other models that came with 5x114.3 bolt pattern.
Asking $200 firm for the set. Will surely fit all Nissan / Infiniti models including 240SX (5-bolt) 300ZX G25 G35 G37 350Z 370Z EX35 FX35 FX45 FX56 etc.
Test before you buy.
