5-point racing harnesses anchor points
I installed GT3 carbon racing seats to my 993, but don't find anchor points for my 5-point racing harnesses. Stock seat belts used one installed to the seat. Should I use seat side plate? And lower center belt?
Anybody?

Here's what I did in my old RSA, which was approved by PCA tech inspection before tracking the car: http://web.me.com/ilko/RSA_Black/How...rsche_911.html

More than you ever wanted to know, but could save you from serious injury or death (you have to download the file from the link): http://www.hmsmotorsport.com/researc...s-installation
If I'm reading correctly about mounting on the "seat side plate", you do not want any belt mounted to anything but the chassis. Whether you do that on the door side with the existing bolt is up to you. But the inside anchor point has to be at a drill through point, with proper backing plate (like Ilko's). Crotch strap location is self-explanatory once you look at the mounting schematic.
For the shoulder harness, it must be attached at the proper height to a proper roll hoop. And pay critical attention to height of the shoulder/harness bar on that hoop in relation to the height of your shoulders when seated AND the belt holes in the seat.

A) I think the GT3 seat has a BK option to bolt to the seat
B)
+ 1. These guys know their stuff.
It was relatively common thinking that the sub belts (or anti sub belts) only held the lap belt in place. Through testing I think with these guys, it showed the subs had to hold up to something like 1500 lbs of force at I think 35 mph. I might have the specifics off, but it was pretty surprising.

I'd use the RS mounts or there is an outfit in England that has a sidemount w/ integral belt mount ala GT3, but I can never remember the name

The BK mounts function the same. The bolt to the seatbelt mounts on the floor, keeping those intact (or not) and provide aluminum loops to secure the two beltline belts.

on the tunnel side you need something like the RS mount or a seat sidemount w/ integral hardpoint for the belt
RS tunnel side stock seatbelt mount
3mm washers that accompany the RS mount, for the other 3 corners of the seat rails
for the subs you can use pad eyes
or GT3 sub bar
here's the whole shebang ready to mount in the car
the tunnel mount for the harness is a pad eye mounted per the factory

a 993 does not have floor mounted seat belt mounts on the tunnel side. The stock tunnel side belt receptacle mounts to and slides w/ the seat. It's best to retain that feature which the RS mounts do. BK does offer a similar item but the RS, the associated 3mm washers and the GT3 sub bar all work as a system, all have 3mm thickness to keep the seat level on the track. The subs and stock belt receptacle will all slide w/ the seat ensuring best fit and performance, only the harness ends will then be mounted to chassis hard points.
