Hello In my Scuderia my Ferrari dealer has mounted 6-point belt before i bought it. The car has the original 3-point belt - and then these 6-point belt from Sabelt. Now i have planned to sell the car, and then the a guy who is interested to buy it, said that its not correctly installed. I have attached som pictures. More than 5 other Scuderias has the same 6-point in these Scuderias. And its sitting perfect when i use it. He said that these 6-point can´t be placed with the original Scuderia chair. Please help with your comment! It is the Ferrari dealer who have installed it from the beginning. best regards.

It is hard to tell from these pictures. But here are a few questions I have just looking at these. 1) the mounting points for the shoulder harness: Do the belts comeout directly or do they slope UP to the shoulders? If they slope up, and the more they slope the worse, then that is generally bad. ONe the one hand, if your shoulders are shorter than the harness slots in the seat, then all that is likely to happen is some rub and compression against the seat. However, if you are not shorter than the holes height then a huge amount of compression would be dilvered nearly instantly in a crash. That would generally break your back. This "might" be the case here but no one is wearing the belts and even then, pictures won't tell the tale very well. 2) The shoulder belts also appear to have the lenght adjustment, forward of the seat. It should be tucked behind. I'm not talking about the one you pull once you are strapped in but the one you use to set the lenght of the strap from the mounting point. 3) The clip on nature of these mounting point worries me. I would need to check it everytime I got in the car to drive at speed. That's just me. It maybe perfectly fine, it just makes me nervous. 4) how are these connecting points mounted to the car? I'm not an expert in 430 harness installation, but I'd want to know from someone who is (430GT are you here?) whether the 430 needs a gusset plate of some sort, under the car that the anti-submarine (crotch) strap mounting hardwear should go through. Same thing for the mounts on the rear wall. Finally, just a word of caution. I HIGHLY recommend never using a harness on the street. I'm 90% sure it is illegal in the USA, but it is a bad idea everywhere. The only time a person should wear a non-ASM harness (like this one) is when they are wearing a HANS device. 3 point seat belts are meant to cause the upper body to rotate (and so do ASM harnesses) in a collision. That allows the shoulders and arms (that are now flailing about) to protect the head from over extending the spinal column. Think about it. In a harness, your shoulders are (or should be) pinned to the rear of the seat. When you collide with something hard, the shoulders stay in place and the head (5-10 pounds at 80MPH?) continues to move forward. Then the next and spine try to stop it. The head pivots on the neck until your chin hits your sternum. At that point your chin has become a fulcrum and your head the wieght that is now trying to stretch the spinal cord. That's very bad. Those are my thoughts. In short, it doesn't look like it is installed incorrectly but it looks like something I'd question too not knowing much about this harness in this car. You should ifnd out how old the harness is. After about 3-4 years they should be replaced. I forget what the FIA or SCCA rule is on this point but there is a rule and it's probably worth following. But it looks like this person could just unsnap all but the lap belts and even that would be a pretty simple proceedure.
Yes they are wrong but if the guy knows they are wrong then he also knows how to make them right. It does not take much effort or $, don't let him blow smoke up your "A". He is looking for ways to drill you down on the price. If you decide to keep the car and track it post back here and we'll tell you how to make them right. The Ferrari dealer was clueless. Sad...but so true on so many things.
Its difficult to tell from the pictures (as you cannot see behind the trim) how they have fitted the fixings. The Ferrari factory harness belt equipped chassis cars have a large spreader plate bonded to the rear firewall. These are to prevent the fixing coming through under the high stresses of belts under high g situations. You can ofcourse get alternatives and you'd normally use a "FIA Approved Spreader plates" made from high tensile steel. If this approach isn't taken, it isn't safe! Image Unavailable, Please Login
The clip in nature is fine as many race cars use this. I know all of the cup cars at my local race shop use this method. My previous track car was set up with these. As for the rest of it, I would defer to guys who race/track their F cars.
