⚠️ Important Fitment & Installation Note:

Before purchasing, please remove the cover of your factory CAS/distributor and verify that your OEM disc measures exactly 50mm in outer diameter. Additionally, ensure that the center hub pattern of your factory disc matches this replacement exactly. Because some RB and VG engines used different CAS hubs depending on the year, visual confirmation is highly recommended to ensure proper fitment.
