Recaro Speed racing seat. I had this in a 1999 911 coupe and 2000 Porsche 911 cabriolet and used it for track events. It has the bottom seat slot for 5/6 point harness. It is very comfortable but provides excellent support during high speed turns. These sell for over $900 new. For more details check out:

Integrated Lumbar System: Proper lumbar support is an integral part of the comfort of an automotive seat. RECARO's proprietary lumbar support technology provides superior comfort and support.
Shoulder, Back and Thigh Bolsters: Driving in a RECARO seat is not all about correct sitting, it is about performance too. The pronounced shoulder, back and thigh bolsters will keep you firmly in place under the most aggressive driving situations.
Adjustable Backrest: Easy manual dial mechanism moves the backrest forward and back for correct sitting positioning in a vehicle.
Dual Manual Seat Back Release: Moves the backrest forward for easy access to the rear seat of a vehicle.
Integrated Headrest: The integrated headrest gives the seat a sportive look, while the functional belt pass-throughs allow for the use of a 4 or 5 point belt harness.
High Quality Foam Padding: The entire seat is lined with thick, dense high quality foam, adding to seats sport feel, ensuring long lasting support and comfort.
