Yes. The F355CH is lower with much stiffer springs and sticky fat tires. Also a carbon fiber wing. It rocks! I read somewhere that there were 88 LHD and 12 RHD cars produced by the factory, but road cars were later converted by dealers, I don't know how many.
There was actually 109 cars made that left the factory as 355CH from 1994-1999. No one may really know the actual answer to how many RHD CH cars that are out there, as there was dealer fitted kits as you mentioned. Maybe someone does know the correct RHD figure, but I doubt it.
I saw a red 355 challenge during my vacations at houston and like 2 or 3 360 challenges all in the ferrari of houston.
Stunning! Are you running it on the street an if so does it still have the original challenge exhaust (with or without the cat) It must sound awsome!
I wish! No it's not a street car, no title, no registration and no liability insurance. Nothin' but track baby! It had open pipes and empty cats when I got it, but I have a stock F355 muffler on it now because I am going to Laguna Seca next month where the sound limit is 92 decibels. My fingers are crossed!
