For my road course tracking with the 08 BLLTT, I have installed the Watson 4 point roll bar, with the harness bar, cross brace and shoulder harness brackets.
The harness is the Schroth 2" 6 point cam lock. The harness angles are correct, with the shoulder harnesses going thru inside the posts of the head restaint, which I flip around to accommodate the helmet. The 2" lap belt is very snug on the hips, connected to quick connects to CoolTech eye bolts (no longer made) at the front seat rear mount bolts. The 2 sub belts thread between the seat bottom and back, to eye bolts, with backing plates under the body. Quick clip in with cotter pins to prevent disconnect. I also use a Schroth Flexi hans device, very comfortable. Also all areas of roll bar and braces potential helmet contact have zip tied certified padding
The unintended consequences of vehicle modification is the rear seat is no longer useable due to roll bar. I put the Ford Racing back seat delete kit with the X brace in. Back seat is now good just for luggage. Also a halon fire bottle on the cross brace behind the passenger seat.
And I machined the former rear seat belt clip in's to fit the OEM front receivers, to eliminate the front OEM seat belt warning.
SO, short circuit, for your canyon carver, to get you locked into the seat, for better control, I TOTALLY recommend the Schroth 4 pt harness with the Anti-Sumbmarine Technology. Uses factory fictures. No further modding needed. And you can adjust the tightest with the seat power control. And in an impact, fuctions like a 3 point, allowing your body to twist and not submarine under the seat belt.
And you can use the Shcroth on the streets, as it AST, like the OEM belts.
If you go to a Roll Bar a lot of more modding needed, including 6pt harness, helmet, hans device, padding...
