XXR 521 - The XXR 521 wheels utilize a classic mesh design with a unique stepped lip. The clean cut mesh spokes are a timeless style that looks at home on a Nissan 370Z, or BMW M3. The real metal rivets are removable and replaceable. Custom paint them, or pick up a set in Red, Blue, Gold, or Gloss Black for total customization! XXR 521 wheels are available in 16" 17" 18" and 20" sizes with staggered widths available.
