Looks like you may have to fabricate spacers to fit in the eye and allow factory mounting in the offset position--not a big deal but something to be aware of if you purchase them.

 

If I recall correctly the only additional parts required are the Racer's Edge Lower Shock Mounts. But, I could be mistaken.
Always planned to install the Koni 3012's but never got around to it and may step up to MCS's when I go through the suspension again.

Like so many things with our cars' suspension, many parts are not plug and play. Racer's Edge mounts would work, and in the past Kelly Moss made some as well that left a stud to support the shock. An AN nut went on the stud.
These Koni's look quite nice, and make adding coil over springs easy. Hope they are still available.

 

I think those Racers Edge lower bolts are only needed if you are doing a torsion bar delete. These lower bolts have a reinforced shoulder to take the stress of the entire weight of the car when the TB is removed, whereas typically the TB takes most of the stress, and the stock lower bolt doesnt.

These shocks would be suitable for a TB delete if you wanted to go that route, as they have solid bushings. Shocks/coilovers with rubber bushings cant take the stress/weight, nor can the stock lower bolt.

 

I have never been able to fit a 14 mm bolt in a 1/2" diameter shock spherical bearing.
From the Paragon site describing the Racer's Edge lower mounts:

The Racers Edge Rear Shock Mount Upgrade Bolt system allows you to install spherical bearing race shocks on your Porsche 944 & 968. the most precise choice is to incorporate Spherical Bearings into the ends of those shocks. Porsche uses a 14mm bolt, which is larger than the ½" bearings which come in all racing shocks. Since this mount is subjected to incredibly high dynamic loads (a coil over holds up your entire rear over bumps etc…) you need a very strong "adapter". This adapter has been specially designed with these loads in mind. Priced per set.
