have one... install is very easy. bolts into stock locations, though it helps to have someone help hold, cause it's a little heavy. as for if it works... not really sure. i just got back from the track, but i never took it to the track without the same mods, so i can't say for sure. i have the rick's x brace and cusco rear brace too, as well as a hard dog roll bar and spoon front tower brace. but with everything on, i can tell you this chassis is ultra stuff. going up and down my driveway the chassis does not bend at all, at least not in the least bit noticeably. in my z06 vette, i could feel the car bending going up and down the same driveway. it's a night and day difference between the z06 and the s2k. how much of that is due to the addons i cannot say for sure.
