After a lot of research and thread reading, I spent this last weekend designing and fabricating my version of inside lap belt attachment points. This is strictly a DE / autocross / street 911 Carrera with no intent of racing. I just really didn't care for any of the thru the tunnel solutions or any of the aftermarket pieces that connect to the seat mounts so I made this......

The bracket is made from 3/16" x2"x2" angle with all mating pieces MIG welded. The bracket has 4"x8" backing plates on the underside on each side. The cross plate that carries the eye bolts retains the angle steel to maintain rigidity (can't see clearly in pic). Mounting bolts are 7/16"x20 grade 8 zinc plated from Ace hardware with locktite.

Conventional stock outside mounting point with eye bolt.

Shoulder straps to DAS rollbar. I still need to make some strap keepers.
The submarine belts (6 point) connect to a cross bar on the seat sliders like I read about on the latest cup cars. This way they stay in the optimal position regardless of seat position.
Thoughts?
Thanks,
Dan
