Notes
- DR Series® spacers fit between the wheel and hub, and require longer wheel bolts (ordered separately).
- DRS Series® spacers fit between the wheel and hub, and require exchanging the existing wheel studs for longer ones (studs are included).
- DRA Series® spacers bolt to the hub with special wheel bolts (included) and provide new threaded holes for the existing wheel bolts.
- DRM Series® spacers bolt to the hub with existing wheel studs and special nuts (included). Wheel is bolted to new DRM wheel studs.
- Similar to H&R TRAK+® DRM Series® Wheel Spacers, H&R’s TRAK+® Wheel Adapters are hubcentric spacers that allow you to change bolt patterns for different wheel fitments.
- TRAK+® Hub Adapters convert the vehicle hub to fit wheels of like bolt patterns but different hub center bores—allowing you to fit wheels from one car to another car and retain proper center bore alignment for the perfect fit. Longer bolts are required.
