To the OP's question, yes. 94-00 brakes are good but at stock car weight and above say, 140whp, you start to need some pretty high temp pads with an expert driver. Sport fronts will give a better pedal and pad life. Carbotech offers them in riveted but least they ofer them. For most other Miata pads, the have a mold that allows a full bonded pad, no rivets. That said, we have won a few national championships and set a pile of lap records running Sport front, 94-00 rears. XP10/XP8 with a 1" master usually. Much above 170whp and an 11" Wilwood front setup starts to make more sense.\

You can actually get tiny NA6 brakes to stop a 2300#, 140wh HPDE car, they just feel like crap and taperdestroy pads in about 3 sessions.

Yep. BTDT, although I'd rather have not. 2400lb PTE car, "139whp" (145wtq), stock 1.6L brakes. It takes good ducting, mega-expensive fluid (Castrol SRF), and constantly flipping the pads to combat pad taper, and they feel like shit, and they wear very fast, but the car stops hard.
