The harness bar is located closer to the back of the seats as compared to others because that is what the major racing harness manufacturers want to see. They want no more than 8" between the shoulder harness mount and the back of the seat.

Shoulder belts must run from the shoulders horizontally or down, at no more than a 20° angle. In cases where the shoulder belts must be routed down to the chassis floor, support by a roll cage bar or harness guide at the appropriate height is essential to establish the horizontal shoulder strap routing off the shoulder/HANS®. Most racing seats are not designed and tested to carry shoulder belt crash loads from downward installation. Severe injury or death could result. A 45° downward shoulder belt installation is possible with seats that SCHROTH has positively tested to take a load measured during a 50 kph [31 mph] and 28 G impact with a 75 kg (175 lb) dummy. WARNING: 45° downward shoulder belt installation is not recommended with HANS®. For the best restraint of the occupant’s upper torso, ideal anchor points should not be further back than 200 mm [8”] from back of user’s seat.
