Personly I think showroom should be as the car rolled off the showroom floor, with a cage, ecu (to stop limp home, speed limiters...etc), basic shocks/springs, and possably the mufflers cut out so they sound better.... like the frogmobile
I can't go into Mazda and get a 3 MPS with front floating Brembo's, and a Kaaz diff. I can see why Octagon gives the consessions out to fix the road cars problems, but it's getting away from what showroom was a couple of years ago.
