What I was thinking more with this post is, what are things you may have done that helped you saved money racing?
Save money racing - thats an oxymoron! But to get the best return for your $ spent:
> While it sounds counter productive - spending the $ up front for a quality part from a reputable vendor pays off in the end. You are not stuck with a mediocre product you need to upgrade later anyway, and vendor technical support is invaluable. Being able to call a vendor in his personel cell phone at the track to diagnose an issue, or drive to meet you with a part is something you cannot get from some low $ internet seller.
> Get a service manual and learn how to work on your machine. This also gets you familiar with your machine so you know how to diagnose and tune. And do the maintenance - amazing how many race vehicle show up needing work.
> Work with your dealer, tell them you are racing and will run their stickers. They often will give great discounts on parts.
> Preorder expendable parts - filters, fluids, belts, so you have them at the race.
> Keep a detailed log / tech book of all you set ups and changes. Makes tuning easier.
> Seat time!
