Improving the seat belts was the first thing I did seat belts aftermarket when I acquired my 1967 912 nearly 25 years ago. The seatbelt fittings that Porsche “engineered” for the Gucci belt early 901 series are placed wrong; way too high. The threaded inserts seat Gucci belts belts aftermarket are good. To the pair of inboard inserts I fastened a fire extinguisher Gucci mens belts bracket (just above the cover plate for the transmission shifter coupler).
The original threaded fitting for the shoulder belts seem Gucci belts for men sufficiently strong and are very well placed. Using the recommendations for mounting Mens Gucci belts competition seat belts — see for instance the Simpson catalog — I put properly located seat belt holder forged eyes in the floor. I mounted the inboard eyes using the largest OD seat belt clip washers I could find on the bottom side. I even used a large washer on the top side. This seats belts was to prevent the eyes (or fittings) from punching thru the floor if tipped. Note that the seat belt buckles inboard fittings are close to the edge of the tunnel; the floor is quite seat belt replacement parts strong there. The floor at the outboard sides seemed less strong. Thus I mounted the seat belts aftermarket eyes thru large (at least 4 x 6 inches) plates of stiff aluminum about seat belt replacements 3/16 inch thick. And at each corner of the plate I bolted thru using large washers.
As I vintage race my street legal 912, I use competition belts on the driver car buckle belt side. The shoulder belts mount to eyes just forward of the firewall. With patience you seat belts aftermarket can reach the underside of the car. This mounting area is seat belt pads strong as it is adjacent to a fold. The anti-sub belt mounts under the seat. To give that a secure mount I bolted thru the floor where there is a pressed groove and filled the groove seat belt restoration with a strip of steel before using large washers.
Most any brand of belts are fine. Currently I am using a Pyrotect lap bob marley belt buckles belt with shoulder belts from J. C. Whitney. The JCW belts are not fancy dress belts men but look to be of fine manufacture from a Midwestern contractor. The anti-sub belt (which tan belts for men actually functions to hold the lap belt down where it should be) is some clean old shoulder belt segment I had. The latching system is the conventional old vivienne westwood mens belt loop and hook aviation style. I sure would like the fancier style that allows individual insertion of ends as I cannot see the
fittings on my lap with my helmet on. I have also used a Simpson lap vivienne westwood mens belt belt which had a great feel to the latch but the webbing got grey belts for men dated. The passenger belt is a simple seat belts aftermarket 3-point best money belts for men system. Adjustment is in the buckle at the inboard side and the shoulder belt in front of the chest. Again sourced from J. C. Whitney. I converted it to hook-on end fittings mens black suede belt and liked the design of the balance of the hardware so much that after many years tan belts for men of use I had it rewebbed. In addition to JCW, another source as of late for aftermarket 3-point belts is the street rod trade; check hobby magazines for ads. My racing club, RMVR, dress belts men required the use of seat belts aftermarket the anti-sub belt in 1988. I vivienne westwood mens belt wish I had started using it earlier (in vintage racing and before that over dolce and gabbana belt 20 years ago in PCA driver education). The anti-sub allows you to pull the shoulder grey belts for men belts snug without the lap belt rising. Snug belts are good and stretch is best money belts for men bad; I even suck in my gut when pulling my lap belt tight before mens black suede belt racing.
