In another thread someone contacted Porsche re: the lack of pass thru and this was part of their answer that the plate wouldn't fit ( like there is no room for the hole in the seat- more smoke!). Let me find it and repost here.

Congrats on having the first US car with LWBs capable of 6-points on both sides. 
Very well done! Nice cutting skills.
Could you post some more pics of your finished cushion mods?

Hmm is there unique wiring under the passenger seat? Just for the occupancy sensor?

Here it is:
Well, little unclear if the plate exists, maybe it's a cup part or a club sport part. PMNA will know, someone have a contact?
My dealer got the following response from PAG on the LWB passenger seat:
"It is correct that there is a difference in the P11 (full bucket seat) on the driver’s and passenger’s side. The passenger’s side seat does not have a 5-/6-point seat belt slot because of the passenger occupant detection system which is required in the US.
It should be noted that if someone wishes to fix a 5-/6-point harness then they must also install a roll cage and a plate on the body shell under the seat to anchor the harness. Neither the roll cage nor the anchor plate are provided by Porsche as they are not homologated (approved) for distribution in the US. This is rather inconsequential considering the regulatory requirement stated above, but it is a factor from a production standpoint."
I'm not a happy camper.

This is rather inconsequential considering the regulatory requirement stated above, but it is a factor from a production standpoint."
"Please ask them what mods are needed to make the seat work with 6-pt without disabling the passenger occupant detection system, and what’s involved in installing the plate they mention.
Please also ask them to cover the cost of those mods. I think it’s reasonable for a buyer to assume and expect that both will work with 6-pt harnesses given that:
• This is a car with track warranty
• These are the only seats they offer which have slots for shoulder harnesses used on track
• There was no indication in the seat description that the seats won’t work with 6-pt harnesses
• If they could make the driver’s seat work, why not the passenger seat?
• The cost of these seats is almost $5K extra
• The previous GT2 seats worked with 6-pt harnesses without any issues, so it was reasonable for a buyer to expect the same with these seats"
Maybe if we all bitch about it, PAG will step up and do the right thing. Otherwise, I wish I'd gotten the regular seats and saved almost $5K, which I could have swapped out for nice track seats at much less cost. Please also ask them to cover the cost of those mods.

Yes, the sensor is below the cut.

Then peal,back the felt carefully where the hole is supposed to go. Use tape to hold it back. Warning, when you cut the carbon fiber the dust goes eveywhere, so cover with tape the sticky side so it remains tacky (learn from my mistake!) Take some measurements from the drivers side, use double sticky tape and place the template down on the shell. Double check that there are no cables underneath where you are going to cut, move them as far as you can to be sure. If you have placed the template properly the foward edge of the hole will line up with the pass through in the seat.
I used a multi tool with a carbide cutting bit and it cut quickly and easily (watch those wires!)I set the cutting depth just deep enough to cut through the CF. Sand and smooth it so there are no ruff edges fold back the felt and that's it! I did check the occupancy sensor to make sure it was not harmed and all is well.

I would also advise to add some molding around the edge and perhaps reinforce the bottom of the seat where the opening is with some thin aluminum plate. It's just to make sure CF won't crack over time from the pressure of the sub-belts.

I used an old Dremel with a carbide cutting bit and attachment
Carbide bit: http://www.dremel.com/en-ca/Accessor...l.aspx?pid=569
Attachment:http://www.dremel.com/en-ca/Attachme...l.aspx?pid=565
My Dremel is almost as old as I am, so the attachment doesn't really fit, but it does on any Dremel made in the last 20 years

Thank-you! Good ideas, but to clarify it is now identical to the drivers side. The hole is in the same location, the shell is the same, and the felt is used to cover the edge same as the drivers side. So any reinforcements should be done to both if necessary. Honestly, I don't think it is necessary as long as the substrap is anchored properly, just below and slightly behind the opening. This will center the belts in the hole which is pretty large for the belts.

Thanks for posting Montoya. Long time ago when I was an A&P mechanic I worked on composite panels all the time. How you approached it is exactly how I will as well. As another poster mentioned I will add my shop vac to the work to assist with the dust and all will be well. Probably wear a respirator as well to be safe.
I was thinking of possibly bonding a doubler (material unknown- maybe CF or AL) to the open seat slot as well if I deemed it needed it. To be honest I have not taken the seats out yet to take a look. Waiting for the sub bar solution and procure my roll bar before I take everything apart. I just want to take it all apart once to carry out the roll bar/ sub bar and harness install all at once.
Thanks for taking the time to post your work. Very helpful for all.

I think adding something on the inside edge is a good idea. I wouldn't bother with any reinforcement. My pole position seats have something like these on the inside of the hole. Would keep belts from chaffing on the carbon which is sort of sharp.
