For anyone who's interested, registration is open for this year's Road America session with the MFBA group. It will be May 4-5th. I've signed up for both days, but you can register for individual days as well.
Individual days start at $235, but remember to factor in the cost of brakes, helmet, etc.
Here's a link to their page:
MFBA Track Days
Since last year I upgraded to the 74mm and I have a H&R cup kit that I'll be installing when its warm enough.
Hope to see another Crossfire there!
