The following links may prove useful to a Miata owner.

www.miata.net - The "official" Miata website! This should be your first stop for any (non club-related) Miata information. It contains links to mechanical information, venders, forums, and other great Miata resources.

Miata.net Forums - The Miata.net forums are a terrific place to ask those Miata-related questions, and have them fielded by enthusiasts around the globe.

Good-Win Racing - From their own site:
Good-Win Racing is your premier supplier for Mazda Miata, Mazda MX5, Mazda RX7, Mazda RX8, Mazda 3, and Mazda 6 performance parts and accessories.

Good-Win is a great place for aftermarket performance parts. Several club members have had very positive experiences buying from them (just ask Ed!)

Fast Forward Superchargers - Fast Forward Superchargers sells the best (in Gram's opinion) kit available to increase engine performance for street use: the 190WHP MP62 Coldside. If you want to add a little more Zoom to your zoom zoom zoom, it's hard to beat the ease of install, reliability, and performance of this kit. Add to that Tom's (the owner) incredible customer service and you can't go wrong with FFS.
