Hey we only ran one race so take anything I say with many grains of salt....Anyhow I put a super cheap removeable wheel adapter ( the type with 6 sides and the silver release button that cost like $ 30) and I hated it. I think they use them for destruction derby's. There was just a lot of play. It was awful. And my standards are pretty low. (Maybe I got a bad one or put it on wrong?)
I just I cut it off and put on a $ 60 unit that is splined and has a center release ring that you squeeze with both hands . It was much better.
To be honest I didn't think it was worth it for me. It does make a little more room when getting in and out , but on the one I ended with you have to play with it a little bit to get it on . ( the tolerance's are pretty tight ) . Normally its just easier to get in and out and leave it alone.
Because my car is street driven I also had to relocate the horn button and now the turn signals don't self cancel anymore.
Good Luck!!
