There is no downside. It's a great program. Mazdaspeed directly supports it's pro racing programs with what it earns through this parts support program. So, in effect, you're supporting the pro teams we all love when you use this program.

You only need to compete in two sanctioned events a year. That can be autocross, road racing, drag racing, off road, etc. You just have to compete in actual sanctioned events, not test and tunes, open track, or drivers ed events. As mentioned, just email or fax copies of your results and you're good each year.

We're in the Louisville, KY area and almost all of the parts we get come from Ontario, CA. So delivery time is usually 3-4 days via ground. FWIW, they're very reasonable on shipping costs and we usually select 2 day service at not much of a markup over ground. Online ordering is easy and they make it very easy to find the part you need with the part fiche on their website. They also have a good selection of aftermarket performance parts. Some at a good deal, some not so much. But, for stock parts, you're not going to find a better deal.

If you're car is not ready to compete, you can get started with a build in progress membership. Basically, send them pics of what you're working on and an expected completion date and you're in. Just make sure to stick with the schedule and update with results when you can.
