DE Track Days - Set up advice needed

[greg9ball]

I have been running a turbo Miata for DE track days and have not been able to keep the car track reliable, so I am starting to consider using my 2005 Boxster S instead. I have a bunch of questions and would appreciate any advice.

Roll Bars:
What roll bar or roll bar extension are necessary for tracks like VIR? I found the Brey-Krause R-3010 Boxster Roll Bar Extension; however, it says that it will only fit the 986. Apparently, it will not fit the 987. Please let me know any recommendations.

Rims and Tires: I use Toyo R888's on my Miata. What do you recommend for the Boxster? I have 19" rims; however, I am considering getting a set of 18" rims for track use to save on replacement tire cost. Any thoughts?

Break Pads: ????

Seats and Harnesses: ????

Anything I am forgetting????

All recommendations are appreciated?

Thank you...
