Hayashi makes centerlock conversions for some of their newer wheels like Impul, that the Skyline guys run. But if you do a search you can find old Hayashi centerlock wheels for Rx3's and old RX7s and maybe some FWD Hondas. Mostly in 14 and 15" sizes.
My wheels are Hayashi H961R's in 18x8.5 and 18x10. I can't even find pictures of my wheels online. I love how rare they are and will probably never sell them. The guy i bought them from was in florida and he had a hard time selling them anyways. I got a good deal on them $1200 as they all had curb rash and were orange. I just had them taken apart, powder coated them silver and had the rash fixed.
