A few years back my brother had a trick little mr2 which had a UCOB MOMO steering wheel. He made an extension to better fit his Kirkey seat. Last night when fitting my custom seat setup, I noticed that the seat would be slightly higher and therefor my knees would rub on the wheel even more. I was reminded of his adapter, and what do you know... it fits perfect. My knees only rub the wheel if im really stretching for heel toe shifting.
