As advertised fit my mrg with nardi wheel with standard horn. The bolt spacing dimensions are 99.9% matched when attaching to nrg quick release latch i noticed a decent amount of bind when i got close to fully seating the surfaces together. I had to start at bolts amd then drive them all down 1 turn at a time slowly bringing the spacer and nrg latch together.Noticed shoddy quality to the machining 1 imperfection and burrs in most of the holes. 5 stars either way it did the job and still looks good
