Jim - Lot's of GREAT info there, I read more than a few of the categories and will say you are quite thorough. I like the options from really budget to kind of budget. One thing I might add is give a 3rd option, say somewhere solid on the value chart, and let them know what they are gaining. Example: I was wearing a $450 suit and likened it to wearing 'Grandma's old wool rug'. I waited until the last minute to put it on and the first thing I did was take it off after the race, it made racing not that much fun, I was miserable when I wore it. Then I purchased a $850 suit, WOW, is all I can say, WHAT A DIFFERENCE- lightweight and cool (it breathes), now I can walk around in the pits and not hate life (SW Florida). Helmets, more $= lighter.
Do you have a catagory on what NOT to go budget on?
Just a few ideas from what I read, for instance the spares list; I am fortunate enough to carry a complete set of upper and lower control arms, and hubs (front and rear). Bolts are in the control arms so basically they are ready to bolt on. Not terribly expensive, but could save your weekend. Really, really budget option? Buy/carry nothing but a fair amount of money ask one of the big teams if they have a spare to sell. I don't recall, but I also carry a spare crank sensor, alternator, and I think you nailed the rest of it.
Tools? I do over kill, but I only fix the car at home with the tools I carry.
Do you have a lessons learned category? - share what you would do over. Me? Better suit once I realized I was in racing for life, good helmet; light and comfortable. Tires, pony up and buy new, I realized my tires were stopping me from learning to drive as I was simply driving not slide and spin.
Tires: Hoosiers will definitely time out, I spoke w/ a Hoosier rep and he said "Tires start aging as soon as they are built", I had a set bubble and separate, I would go no more than 3 years max on Hoosiers, likely the same for Toyo's. In spite of what I was told, Toyo's do not carry the same performance for 20+ heat cycles (in my opinion) maybe 3/4 race weekends max.
I see you have a spot for DIY alignment - set up is always the hard part. Not only doing it but picking your settings, maybe you could give them a good baseline set up and elementary trouble shooting i.e. Rear end loose, lower it 2 turns (or raise the front ), something like that.
I was very surprised on how complete the sections and the information is; your writing style is easy to read, grammatically correct, and void of too much prose that authors include when they don't have much to say. All in all I thought it was great and myself would have read and re-read it many time when starting up.
