Wow, this thread is horrid.
Roll your car a couple times. Smash it all up. Have only seconds left to live. Now rather then cutting just one belt; still a side from the roof and what ever else; they now need to cut 6. Lessening your chance of living. O.E seat belts of today suffice very good results. If they didn’t. Well come on. Racing seat belts are for just that. Racing.
Why the hell would you want a harness if you never track your car? Even if I did track my car. I would hate having the harness laying in the car when Im not using it.
Go get some “Titanium Lugzors” while your at it.
