In addition to our full lineup of drivetrain components for all NA and NB Miatas, we're also a 949Racing 6UL dealer! We stock 15x8 and 15x9 6ULs at our Northern California facility and are able to ship anywhere in North America, Asia, and Australia. With 8 years of experience on 6ULs, we can also provide detailed fitment support for your exact application.
If you're looking for 6ULs for your NA/NB, look no further.
15x8s will bolt up to any NA/NB Miata with no modifications. That means stock lugnuts and stock studs are not a problem.
The alloy lugs provide more wrench clearance (19mm vs. stock 21mm lugs) and make tire changes a bit quicker.
Any standard rubber valve stem will work. The alloy valve stems are lighter, but more importantly, they fasten more securely to the wheel (easier to check/set tire pressures) and they do not degrade with heat like a standard valve stem does.
