Have a set of month old Motorsport tech/adaptec adapters. Have seen at most 3000kms (h2oi and back)
They are 4x100 - 5x120.65, hub centric (57.1mm) and wheel centric (for corvette wheels)
2 are 18mm
2 are 20mm
Come with all necessary hardware.
Very well made adapters (not my first set from adaptec), no vibrations, all threads are intact (always use my snap-on torque wrench)
Reason for selling is I'm changing up the center's on my rs's for 4x100 ones so I can run wider lips.
They were 400.00 from motorsport tech after shipping + 50 on duties.
Asking 400 OBO
Here's them on my car with the rs's
