My last post for the evening (I hope). ECTA leathers must have metal zippers, and if the suit is two-piece, the zippers must be a: all the way around the waist, and b: the zippers must be attached to leather or strong fabric (vs. attaching them to the soft and supple liner of the suit). Not perforations of any kind, anywhere, is the best -- but a few perfs (five-8 or so), in areas smaller than the palm of your hand, will be accepted. Perhaps in the armpits, say.
NO REPEAT NO fabric is best. That part is simple.
Remember -- if you're on a 14R you'll be in a class where the record is over 175, and therefore you'll be required to have body armor. If you've got the time and the bucks you can have it built into the suit now, or you can purchase armor that slips on/straps on. But armor is required over 175 (that is, if the record in your class is over 175 - whether you're going that fast or not).
Back to perforations/fabrics: Remember, this is Maxton (at least you put your question in the ECTA column). You'll be completely zipped into your suit for about a minute or three, and comfort/ventilation isn't going to be high on your list of things to worry about a lack thereof. And also remember that this is land speed racing -- you don't need a suit that's super-flexible and would allow you to climb around on the bike like a monkey or V. Rossi -- you'll be scrunched into a tiny lump and trying hard to get even smaller, so you won't need lots of the flex as fabric would provide. Make sure that the suit fits you when you're in the tuck, though. Some leathers manufacturers make their suits based upon the buyer's measurements when in the position in which he'll be using the suit (in other words, when tucked, not while standing on the bedroom floor).
Back to your scoops: Are they closable with metal zippers? The should be.
I think I've got it right. If I don't, and you show up with leathers that are way more than required to pass -- well, the rules are a minimum, remember, and skin grafts are less fun than sweating.
We look forward to seeing you at Maxton. Make sure you get your ticket reservation in soon (for the Banquet on Saturday night).
