I have the same steering wheel. I sent it out to a guy in Latvia that had it wrapped in Nappa with tricolor stitching. I get compliments all the time on it. Feels just like the f10 m steering wheel which is the thickness i requested. I think I paid around 200-250 to get it done including shipping and everything. If there is some interest I can take a pic and get the guys info.
