    Certainly the FIA / MSA don't ask for this.

    It could have a small torsional benefit, through effectively tying the sill to the tunnel, but ideally could do with being attached in several places to achieve. Even then, it's still just floor tin.

    Requires advance planning of crotch strap fittings / belt runs obviously.

    more hassle than its worth then.

    Thats fine, just thought I`d ask. I`ll be using box section for my rails I`m fitting, why do people use tube instead ? (although I see some do use box) [:s]

    (Seamless) tube is used as it continues the theme of roll cage construction.

    Ah, so its a nice to have rather than requirement ?

    Its twice the price (at least) of CDS, thats all.

    The FIA require 35m x 2.5 tube, but glancing at the MSA Blue Book - here - I can't see anything.

    Loads of people use box section in track cars, so it's personal choice.

    Per the MSA (for racing) they have to meet the description of 'fit for purpose'.

    Box/tube - seamless or non-seamless are all fine.

    Some FIA seats come with indications/instructions apparently.

    HTH.

    Always good to have the info :thumbup:

    Although I bet not many on here have sleeved the box / tube. Suppose its different for trackdayers compared to those racing.

    I`ve done things that are safe but probably don`t confirm to the Blue Book.

    Mike, as mentioned the photobucket had maxed out. All pics are back up :thumbup:


    Quick pic of a mid-'90s works Impreza co-driver seat rail, profiled and sunk into the floor as far as possible. The side of the tube will be cut open due to the profiling, so it is welded along the lower edge for a distance.

    Bag of potatoes, so no arguments about sightseeing. He or she sits as low as possible :thumbup:
