I was thinking of my M5 (which I've been autocrossing since the 330i ZHP went to GA Tech

I could be wrong but I'd bet you might be surprised what could be done in a mildly prepped M5 in ESP. I'm not saying you could win Nationals with it but I'd bet you could win a few Tours and Pros depending on who showed up. Unless those things really weigh 4600lbs+, I doubt you'd need to lose 1000lbs.

Something about the ZHP destroying the edges of front A6s in less than 20 runs kind of took the fun out of really trying to use a camber-challenged BMW for a season of stock class autocrossing at a serious level. $280 a tire and all...

Hence the comment about the R1s I switched to on the 330i. I really doubt that any top competitor at the Nationals wants to use R1s, but I suppose stranger thing are possible.

I definitely know the pain of that all too well. The Type R kills a set of front tires in less than 20 runs as well. It's the main reason most people quit running them. Well, that, and they get stolen. There are a lot of cars in a similar boat so it really comes down to what you're willing to put up with.
If you're planning on only running a few National events in a year (1 Tour + 2 Pros on average), you're really not talking about using up that many tires. If you happen to win some along the way, that obviously helps as well.

I can understand not obsessing about car preparation to a point, but do you think it makes since to ignore it THAT much?

I mean, maybe it's just me, but if I was going to take the time to compete at Tour events and go to the Nationals, in addition to spending all the money on tires, hotels, gas, entry fees, tires, tires...take time off from my business, convince my wife it will be a "fun" experience, etc.. I really can't imagine not bothering to ensure that stuff such as suspension bushings aren't worn too much and ensuring the car is properly aligned -- basic stuff. I guess that is just the engineer in me not wanting to shoot myself in the foot first and then see if I can win the race?

Hey, I never said it was wise to follow my lead. One of the first things I told David when we started co-driving was to keep an eye on me and don't ever assume I have any idea that I know what I'm doing.
But really, my main point is that you (collective "you", not you specifically Chuck) don't need to have the perfect car to try one of the bigger events. Nor do I think you should use it as an excuse to go out and try it once or twice to see if you like it. If you don't like it, no harm done and you can at least have the experience of getting out of your local sandbox for a different perspective on things. If you do like it, then perhaps it is time to start thinking about putting yourself in a better position to win.
Or if you're like me and your current car is starting to act up but you're too lazy to fix it, just buy another one...
Honestly, the main reason I didn't look over the Type R very well is that is was fast enough to win when I picked it up. Considering I didn't have a garage or decent work area at the time and the car was doing well, I didn't see any reason to mess with it. Of course, it's been all down hill from there...
