Those Germans can even make boring things sexy in a functional sort of way.

Almost, its a regular rear seat based covered with trunk liner (very formable carpet) to match the carpet in the car.

| Makes this one the car also more stiff? Or is it only protection? |

Not enough mounting points to stiffen the car. Looks like a glorified harness bar than a roll over bar. Certianly better than nothing but I wouldn't bet my life on it if it went arse over tit!!

harness bar and 6x9s. Tsk, tsk, something's gotta go 
That bar looks very similar in principle to the custom bar I had made for my club sport project:
It appears to attach at the same points, which are VERY strong. My bar was very snug and somewhat of a challenge to install, but once in, rock solid. I'm certain that it will add to the torsional rigidity of the car, and much more so than a simple harness bar. I also think that based on where it bolts in, it will provide as much, if not more rollover protection as the autopower roll cages that are supposed to be welded to the sheet metal. The attachment points are very robust.

If you read carefully, you'll notice I never referenced it as a roll bar. Any roll bar in a 924/944/968 serves to strengthen the b-pillar area, which is already the strongest part of the roof supporting structure. If you look at photos of these cars when they go dirty side up, it is the a-pillar that collapses, and any roll bar is not going to stop that. If you want roll over protection, get a fully WELDED in cage, anything else is a harness bar despite what its advertised as.

Nice call Dan! I will not take responsibility for the speakers, they were there when I bought the car.
You may remember I ran the equivalent autopower setup in my 924. I am much, much happier with this setup. The autopower bar is connected to the weakest part of the structure, the floor pan and the wheel wells. I'd much rather have my harnesses (and thus HANS) connected to 4 points of the car that were designed to take seatbelt stress in an impact. I looked at the Redline setup like yours, very nicely made and John is a nice guy.
A full cage isn't an option as I still street drive the car to autocross and track days.
Now, while we're "tsk, tsk"'ing, I have to ask why you didn't put a Heigo setup in your club sport as per the factory, pictures for your enjoyment below...

Well, part of the issue is that the Autopower cages aren't very good at being cages and many aren't installed properly. They are better than nothing and meet the regs, but only just, especially when installed poorly (landing pads too small, no backing plates, etc)
Second, the harness bars you guys have will not work in a rollover, the force of a 2000+lb car landing on those single-sheer mounted bolts will merely snap them off or bend the bolts/structure until they fail.
Adding a second layer of steel connected to the frame that sandwiches the ends of the harness bar with the mounting bolts running through the resulting "sandwich" will improve the overall strength, the loads are still in the wrong direction, but the bolts may not sheer completely just bend.
The stresses involved with having a 100+lb person pull on those mounts in the event of a crash are considerably different than a 2000+lb car landing on them. Just simple physics, the forces are potentially orders of magnitude different.
A properly built rollbar/cage would tie into the frame, not the floor and spread the loads into the frame to prevent the frame and cage from collapsing and compromising driver safety.
Then you have to factor in the situation that some of the newer cars (not necessarily 924/944) have seat belt mounts that are meant to break away slowly to provide a more gentle deceleration in the event of a serious crash. These are usually found on cars with air bags or active restraints.

None of the bars pictured in this thread have been presented as "roll bars" by the people posting or using them, so I'm not sure who you are arguing with. A roll cage provides roll over protection, as I stated above, everything else is a harness bar.
The advantage to the type of bars posted is that you can attach the harnesses directly to them. Most harness bars (think Brey Krause, Weltmeister, etc.) are harness guides. The shoulder straps run over the bar and down to the rear seat belt mount points. As you know, the longer the run, the more belt stretch you introduce in an impact, so guide bars are far from ideal.

This setup is way better than factory belts, I think that is all he's trying to do.
