upper harness mount position

[TalonMotorFabrication]

There is an answer to this that might not be too popular but I'm going to say it any way,forget 4 point harnesses and fit inertia reel seat belts.
Reason 1: keep the same seats for IVA and post IVA
Reason 2: you sit at the end of a long bonnet in these cars and in 4 point harnesses you can't lean forward to look left past your passenger at junctions
Reason 3: have you ever taken a 7 into a pay at entry car park or at the toll booth and had to undo your 4 point belts?
Reason 4: one size fits all no need to adjust them for every body that gets in the passenger seat

I leave you to mull that little lot over before every body shoots me down in flames...
