AFAIK power everything is taken out, windows, seats, locks, mirrors. No ABS, audio system, A/C, sound deadening, interior light/handles, keyless entry and rear wing and comes with a 5sp. I do remember it coming with a LSD in place of the open diff up front but i think they added that to every model but don't quote me. I've read it's a 146lb difference and when hitting those twisties, every pound counts. Basically a no frills version of the Evo with a lower price also.
