Set of 4: Each product is sold as a complete set of four pieces, one piece for each wheel.
BBS has been in performance wheels since the 1970s. The DTM-era RS, RZ, and CH-R series all have specific center cap specs, and modern BBS wheels continue that tradition of precise fitments. This XL floating center cap keeps the BBS logo upright as the wheel rotates. Counter-rotating, logo stays level. Set of 4. BBS bore sizes vary by series and model — measure before ordering. Contact us with your BBS wheel model if you need sizing confirmed.

You need one of your current caps, a ruler or tape measure, a sheet of paper and a pencil.
Tap your size to select it.
Pick the size closest to your number. A few millimeters either way is normal. 177.8mm (7") isn't available in Brushed or Polished Aluminum.
Start at the last whole number, then count the little lines past it. Each one adds 1/16 in. Example: 5 and 11 little lines is 5 11/16 in, our 145mm size.

Flip the cap over. Measure the raised inner ring that holds the metal clip, outside edge to outside edge, straight across the middle.
Don't measure the hole inside the ring or the wide outer cap.
Tap your back ring size to select it.
