That is a push rod inboard suspension, there are several benefits to this. Mounting the coilovers horizontally on top of the gear box removes the coilovers from the unsprung mass, and essentially makes it sprung mass. You can tilt the coil overs any which way as long as the lever arm is situated in such a way that it will input forces directly into the coil over. This way of mounting the coilovers is convenient considering the ammount of space you're working with.

Another feature of this suspension setup is that everything is mounted directly to the gearbox, there is no additional frame work for the back of the car. Im not convinced this is entirely safe as the bellhousing will be taking all the twisting forces brought on by the rear wheels in cornering and bump. unless there is more to the rear frame that is not shown in the pictures.

A benefit of pushrod suspension in open wheel cars is reducing aerodynamic drag.

All of the GT40 suspensions ive seen on this site have had radius rods, in the rear, which is kind of an old suspension style. This style you are seeing in the picture is used today in open wheel racing.
