Both BEGI and Sebring make superchargers for the Miata. Back when I was considering keeping my Miata I did a lot of investigation and came up with the following:
Customer Service: Both are pretty basic, but Sebring is better.
Install instructions: Sebring again.
Technical: BEGI had the edge, intercooler really helps.
Performance: BEGI again
Installation: Sebring - cleaner, easier.
While you could find fanatics on either side, BEGI fanatics were more...fanatical. There were almost no Sebring fanatics, but loads of satisfied customers.
I know the Z3 installation may be different, but I had decided that if I was to choose one, I'd probably go with Sebring because they seemed to have a more conservative "mass market" approach. If I was more of a gearhead, I think I would have gone BEGI.
