Thanks Dave, did not know that. And thanks for the pointer on wheels, fal.
Eddie, it is not like that Magnumforce front end, if that is what you are thinking. That thing is a disaster, with the coilovers mounting where the shocks go.
I cannot believe someone thought that putting all of the stress of the suspension onto the sheetmetal inner fenders was an ok thing to do. The AlterKtion one has its own integrated upper coilover mount. It does use the stock upper A-arm mounting. The XV one requires cutting up the sheetmetal and welding a heavy-duty upper mount onto the top of the frame. The alterktion only has 4 or 4.5" of travel to the coilover, though, due to the fact that it's designed to require no modification, so the coilover sits below the original shock mounts.
The Alterktion uses mustang II spindles, allowing for a lot of common brake kits and some pretty big components to be used.
The XV kit uses 06 and up corvette spindles, making brake choices very pricey.
Looking at manciniracing, those are huge brake kits that you can fit on a pretty stock front end! I am set on eliminating torsion bars and lightening the front, though, so a redesigned K frame with new spindles is what I'm going to have to work with.
