Well, if you got the dough for it, it'll definitely give you an edge, I doubt very many would be running it in the B class, so I'd definitely say yes. Any edge over the comp. is a plus.
I seriously doubt that there will be more than handul people at a on 'shees at a nat., much less with a LT front-end..... hardly even see a 'shee at the local races. I guess if you got the cash to blow then go ahead, but a nice +2+1 setup will gain you 1-2'' of travel as it is.
