anti-sub straps

[fve]

I have gone through postings on rennlist, here on teh RTR forum, the instructions for harness mounting from the Schroth web site and even the rules from PCA club racing. and, perhaps i am dumb, but i am still not sure about the recommended mode of securing the anti-sub straps.

situation. 996 gt3, had it for a year now, new to DE (did a little last year). Want to do more this year. Goal for the winter for focus on safety equipment. Obtained gt3 seats, DAS sport roll bar. I am also getting some used schroth profi III harnesses.

first, i know, i know, used harnesses are not ideal. the giver is going to new harnesses that work better with the HANS and they are a good starting point. I may opt to also go for a HANS in the future (i am sure that broken cervical vertebrae are no fun) so this will allow me a place to start before i buy my own (new) harnesses.

The big question is about securing the anti-sub straps. All the stuff that i have read (listed above) indicates (to paraphrase): install according to manufacture recommendations. Ok. i understand the 0-20 degree angle, the separation of the straps. the seats come with (i think OEM) a subbar. Is if ok to secure the anti-sub straps to the sub-bar or do i need to drill/weld backing plate, eye-bolt, etc to the sheet metal.

I would love to ask in person, but i worked last night during the meeting and i have to work (again) on Saturday.

cheers, and thanks in advance.
