The frame was cut for the a/c but then filled back in after realizing that we didn't need it. I'm running the S&P front drive which puts the a/c on top. The section in the frame where the u-joint meets the rack has to be cut out to clear the steering shaft/u-joint. If you go to BRP's website there's some pics there of a subframe with the mod. They give you the piece that goes in the frame to give you the proper clearence. It's basically just a piece of exhaust pipe thats bent and cut open/spread apart, but it works fine. The kit comes with billet steering arms that bolt right up to the ATS spindles. As far as cost compared to buying DSE's, the rack is around $1200, sway bar $250, front suspension $2300(for everything),$650 spindles,totaling $4400 in parts. If you do all the work yourself it would be a pretty good advantage. If you have a shop do everything, it would still, probably be less overall, but probably not low enough to not buy their setup. I don't regret, at all, what I did, but if I had to do it again, I would definetely go with there's because you also get a hydroformed frame and wider wheel options. But again, if you do the work yourself and if you dont do their front suspension, then there's a huge price difference. Good luck.
