coilover selection

I don't see the link, but I think you are referring to Speedtech's website. First, I would recommend just buying the ATS brackets rather than fabricate something yourself. There's already enough fabrication involved in installing the ATS brackets alone, so to add to the fabrication of the brackets would create unwanted headaches. I am in the process of installing this setup on my 67 Camaro. I have dealt with all the headaches of it and have worked out all the kinks that came with this install. Tyler, original developer of the ATS brackets, as well as James of the OLC Camaro confirmed to me that I need to run the 5.2" stroke coil-over. That spec matched my own measurements. The 5.2" stroke coil-over is the same length shock as my rears with the ridetech Airbar. The standard upper cup, holds the spring at the top of the shock, that comes with the ridetech coil-overs interfered with the ATS bracket. I had to order the 1.25" drop cups to create clearance. I was told to use 10" springs, so the drop cups work better with the 10" springs on such a long shock. Also, I am using the double shear brackets that weld to the bottom of the lower control arm which provide an attachment point for the bottom of the coil-over. The double shear brackets are $50 extra over the $250 price of the ATS brackets. If you chose not to use the double shear brackets, then you can buy the trunnion bars which allow the shock to attach in the traditional manner. They are a $40 extra cost from Ridetech. The double shear bracket is a much stronger method of attaching the bottom of the shock. The coil-overs are priced per pair. That's pretty much all the information you will need for this setup. You will definitely need aftermarket lower control arms that are strong enough to handle coil-overs also. Stock lowers 'will' not be strong enough and there is nothing you can do to beef them up really.
