Fitting them in is a real pain in the arse, as my cars fully stripped it helped, but i still had it bouncing off the screen, and i also ended up taking both front doors off and removing the steering column, infact it was that tight a fit, once it was in it didn't move, and that's before it welded in place.
Well worth it though, by the time i'd got it shot blasted and a friend to weld mine in, it still only stands me at £650, bargain for a full fia cage

ps, Matt i've not forgot about your offer with the cup racer loom/ecu etc, it finally arrived but i still need a few more bits of the wiring before i've got enough to run the car, or at least attempt it
