I am waiting for the Club Sport seats from the euro car to start popping up and I will run them with 5/6pt Schroth harness. I haven't been able to find them yet and I like the stock look. I did Sparco's on my 997 gt3 and they just didn't look right because you couldn't match the color. I would do the harnesses now (I probably should if I track it before new seats), but I don't want to trash the stock seats from the belts rubbing on them, nor do I even know If 5/6 point would work with the seats because of how they are shaped.

Please refer to the pictures below.

There are 2 holes on each side for eye bolts for attaching the belts in the rear, and then a bracket on the outside of the seat attached to the cage. Then use the stock part where seat belt attaches to the body on the center console side. I called GMG actually to confirm because it was different from the 997 bar.

The SW bypass is great, I just feel like it's a louder version of the stock exhaust and I'd like to change the tone so it sounds more racey. The equal length headers should definitely give it a better tone and I think once the headers are on, which include high flow cats, there will be no need to replace the side mufflers because it will be loud enough. But for the sake of me being impulsive, I'll cross that bridge when I get there. Also, correct me if I'm wrong, but I haven't seen anyone marketing a full cat back for this car.

As far as performance is concerned, I don't expect much because of how high strung the motor already is stock. I would guess 10-15whp max.

Bottom line, I'm in it for 80% sound, 20% performance.

Congrats. I also have the GMG bar in a Carrera S and like it a lot. Thumbs up on the red taillights, too.

I may be able to help a bit--I have the GMG rollbar, OMP race buckets and Schroth 6-pt harnesses in a 991 Carrera S, which should be a similar interior setup as the GT3. The distance from the seatback pass-throughs for the shoulder straps to the rollbar mounting points for the straps is something like 17in if I recall correctly, which means that the shoulder straps mount right next to each other on the bar, without crossing over. I read the Schroth instructions very carefully, and at this distance, it's recommended to have the center point of each strap's webbing 3in from the other strap's center point, which means they sit right next to each other on the bar. If the distance from the seats to the bar's shoulder strap mounting points were any greater, then you would have to criss-cross the straps on the way back to the bar.

For my setup, we used Recaro low-profile sliders, OMP HTE-400 driver and WRC passenger seats, a combo of Brey-Krause and Planted side brackets, a Brey-Krause anti-sub strap mounting bar, a B-K fire extinguisher mount, and Porsche female seatbelt receptacles mounted to the inboard sides of the seats. Stable Energies in NJ put the package together for me–-they're a good resource.

This pic was before the final adjustment of getting the straps right next to each other on the bar:

Thanks, that's helpful. Also used Stable for my Boxster harness set up. My car is due Nov, so thinking about this. Maybe by then there will be some word on sport buckets for US.

Engeljizzle, your car looks very good. Looks like our new dealer Precision Sport Industries in Florida took good care of you!
