    Hi, just bought my first Ferrari - had a burning hot 991 GT3 that I got tired of collecting dust in the garage, while Porsche does R&D for my money.

    So I am now the owner of a 430 Scuderia.
    It has 4-point from the factory but not the cage.
    What is peoples take on this, is it stiff enough if it lands in the top or does everyone put in the cage?

    I have the setup and was asking my self the same question when I bought the car. I asked Ferrari and they say the car is stiff enough as it is without the roll bar, but I am still not sure I believe that...

    I haven't really found any good alternative roll bar either.

    So did you put in the cage?

    crash deltas are thought of in G's. So a 35mph delta is about a 20g crash. 45mph crash delta is about a 50g crash. IIRC federal mandates are that roof structures are supposed to survive only 3g's! So if you plan to track more than occasionally the conventional wisdom is to add a 4pt rollover hoop. It is not a cage until you have 6-8 bolted/welded connection points to the chassis and that means door bars of typically "X" or NASCAR variety. Then there is the urban legion of never drive a streetcar with bars that you can hit your head on, i.e. no cage in streetcars. While this is repeated ad nausium on car websites very famous people in the race safety industry such as Joe Marko of HMS motorsports the Schroth harness importer poo poo that cliche. If you have bars you can hit pad them with SFI 45.1 rollbar padding and what Joe Marko says should be reliable.

    I agree.

    Problem is that many people that drive with cages on the street actually do it for show or simply don't pad them - as insane as that might sound.

    You have made some significant simplifying assumptions in your calculations. Those numbers represent near-instantaneous inelastic collisions against an immovable object (M1 >>> M2). You forgot to state the time of deceleration, without which, you cannot calculate the g-force.

    For instance, a constant decelaration from 60 mph to 0 mph in 1.0 second, representing an elastic collision against a fixed object (such as a car with a collapsible crash structure forward of the cabin, and an airbag + seatbelt) is less than 3.0 G's exerted on the occupant. Easily survivable and does not exceed the design specs of the safety cell of most modern passenger cars.

    Your math is right but your assumptions about crash pulse duration are wrong. What I quote is generally accepted in the industry. Dale Earnhart's fatal crash delta was 42-44mph.

    I totally agree that none of my assumptions for a passenger car crash apply to Earnhardt's crash in a NASCAR stock car. A tube frame stock car has no crumple zone to spread the impulse load, nor does it have an airbag to physically cushion the driver. In this instance, the seat belt also failed to spread the impulse load. Also, the steering wheel acted to compromise the living space within the safety cell. This very unique circumstance was as close to an inelastic collision as you can get, and exerted a force in a point load on a vulnerable part of the body.

    Nope both are complete safety systems for their own environment. A stock car is designed with crumple or parts that come off to spread of energy. You want inelastic, how about a utility pole? I would take racecar hazzards in a racecar over oem systems and a k rail or utility pole. Government and ihs crash test at 35mph. Earnhardt died at 42-44mph. His crash is not the only one. We loose a clubracer about once a year. We loose an hpde'er about every five years.

    That is a nice job. I wonder if it still enables full rearward adjustment of the seats.

    The part no (but no price) are in the parts book @ Ricambi Ferrari 430 Scuderia Parts : Table 121 - RACING SEAT-4 POINT BELTS-ROLL BAR

    In the UK Eurospares parts book it shows at about USD 4000 plus sales tax

    Looks like all you needed to do was ask your dealer....

    Thanks!

    I'm also getting quotes from iND/fall-line and iND/Ai (one pictured above). We'll see how they come out...will share what I'm able.
