Racing parts kit, including cage?

[imon_2nd]

Thanks for the replies, gents. Very helpful.

To clarify, I'd like to make my Boxster competent for track days, not "real" racing. That said, I did a lot of wheel-to-wheel driving with other track day Miatas.

For my Miata, which I also drove on the street, that meant:

Roll bar with 4 attach points
Lowering springs, shocks, sway bars
Bigger, lightweight wheels
Bridgestone RE-11 tires
Cat-back exhaust
Cold air intake
Supercharger
ECU and ignition controller

For the Boxster I don't need a supercharger.

The 17-inch factory wheels seem like they will be good enough. True?

Do I really need a full cage, given that the Box has roll bars behind the seats?

ECU flash?

Seems like most of the money to make my car an "OK" track day and street-able Boxster will be in the suspension.

Cheers,

Dave
