    Unfortunately itís a No No as the rear bulkhead on harness optioned cars is actually different. As well as the anchor points needing to be engineered into the chassis legislation from the 458 tipo on also dictated having Electronic confirmation of closure too. It would really be easier to change your car for a more track / sporting spec of car.

    Just some advice if you go down this route.
    The MOT regs dictate that the harness must be able to be released with one hand. This means that a cheaper less engineered harness like the ones that have seat belt style (red button) closures are legal but the ones you want with the aerospace twist closure are not. The belts have to be BS approved to pass an MOT but many are not because the are made to FIA standards.

    Whether to fit harnesses to a road car and use them on the road is a big source of debate because of what harnesses canít do that an inertia real belt can do. In the event of a accident the harnesses keep you upright, where-as a 3 pt belt will let your body bend to the side to lower your head. If the crash involved the car rolling or flipping as/if the roof crushes down the harness would likely lead to serious injury whereas the lap belt would potentially save you. I can vouch for this having had a crash that left me upside down in a car with a seriously crushed roof. The taller you are the more you might think about it. Harnesses are designed to be used with roll cages and helmets.

    Different makers take different approaches when it comes to harnesses in road cars. Ferrari for example take the cheap belt approach and offers a road legal roll cage as an expensive option but others like Porsche engineer the car to have both a regular belt (for road use) and harnesses with a roll cage for track use. For this to be legal they must not share the same hardware mount points so bear that in mind. Also obvious but check any item you buy in this regard works with a RHD car.

    Hi All, I have checked out the Fabspeed setup, and looks like the crossbar fits to the belt Bolts on the B pillars but then they have a third fixing which goes to a Child Safety seat Bracket on the Rear Bulkhead behind the passenger seat which does not appear to be on my early 2010 Car ??? I have emailed Fabspeed but not heard anything back, so maybe they only supply for US spec cars, any help appreciated, Regards DM
