I havent observed the clearance issues on the adrenaline one that Mike mentions (simply as i wasnt looking for them) but my take on the beam is that its fantastically well made, great quality adjusters and nice finnish to it etc
On the one I adjusted though it did NOT have actually enough adjustment available IMHO, I wasnt actually able to quite get the toe to where I wanted without having to dial in slightly more camber than I wanted, not sure if thats specific to how its fitted on that car in question, or if thats always the case.

But as a result I would have reservations about buying one personally based on what I saw, especially when coupled with the required chassis mods that Mike mentions, where as the ahmed one has been proven time and time again and I believe is a straight fit.

Im sure that there was nothing up with the Adrenalin one that couldnt be fixed though, so dont think im slagging it off as useless as im not, but essentially it still requires a small amount of development work IMHO (especially regards to fitting ease from what Mike said)
