The vehicle list above confirms your year, make and model. The points below are not part of that list — they depend on the wheels and hardware currently on your vehicle. Please verify them before ordering.




These checks apply to the hardware included in this kit. They depend on what is currently fitted to your vehicle, not on the year, make and model above.



The plate is 6061-T6 aluminum with both mounting faces machined flat, so it clamps square between hub and wheel; an anodized surface shields the alloy against corrosion.
Each M12x1.5 wheel stud is SCM carbon steel in Grade 10.9, pressed into the plate so your wheel torques against fixed studs rather than loose hardware.
The wheel side takes M12x1.5 lug nuts in the seat style your new wheels call for, so aftermarket alloy or steel wheels can both be run; wheel-side nuts are not included.
Open-end nuts with a 60 degree conical seat (a plain tapered cone), 22 mm height and 23 mm (0.9 in) flange bolt the plate to your factory studs with a 3/4 in hex socket; the nut count is in the title.
The hub side is double drilled, so one plate bolts up to either of two factory patterns while the nuts' conical seats center it on your studs; this listing names its patterns in the title.
Moving the wheel outboard adds track width and can open caliper clearance for aftermarket wheels; the gain equals the adapter thickness carried in this listing's title.
Follow the sequence below ? fitment is everything, so read Step 1 carefully.
Confirm the hub's factory bolt pattern matches this plate and that your new wheels are drilled 5x112, then dry-fit the bare adapter on the clean hub face.
Seat the included open-end nuts on the vehicle's own studs with a 3/4 in hex socket and tighten evenly in a star pattern until the adapter sits flat.
Hang the 5x112 wheel on the M12x1.5 studs, fit your own wheel-side nuts, and torque in a star pattern to the wheel maker's spec; recheck torque after the first drive.
eBay's compatibility list matches by vehicle only. The wheel-side facts above — seat geometry, hole clearance, installed depth and usable thread engagement — still need your own check. Message us through eBay before ordering if anything is unclear.
