I just finished re-installing the cage in the ST. Now its time to bolt up the harnesses. I will be mounting the shoulder straps around the cross bar built in to the cage. The hip straps will be mounted via M12 nuts welded to my seat brackets (factory mounting points for a 71).
My question is about sub belt attachment. I marked the floor directly under the sub belt hole in the seat. I plan to mount the belt so that the belt is 1" behind this mark. I will be sharing track time with my father who is shorter and this gives a good comprimise for both seating positions.
I have a question about afixing the mount to the floor. I am looking at a permanent installation. Clipping to an eyebolt will not work since I don't have enough clearance under my seats. The belt comes with a bolt in clip. I am under the impression this should be mounted in a manner that places shear stress on the bolt. Both options below will have proper backing plates on the bottom of the floor.
Mounting option #1 - bolted to the floor:
If I bolt this mount directly to the floor the bracket could pull upwards and bend, comprimising strength.
Mounting option #2 - U-bolt
I found these grade8 u-bolts made for making custom cable setups. This arrangement should allow for correct shear position and allow a little angle play in the setup.
Let's hear your suggestions for mounting this up. One better than the other? Other options?
Thanks
