Gordon, perhaps it is not a National BMWCCA policy even though I was told it is, but as far as the BMWCCA chapters that I have talked to and instructed with, they do not allow ANY convertibles, not even a Miata with a rollcage and a hardtop bolted in. Definitely not a Z3 or Z4 in any way.

PCA does allow them as long as they have rollover protection. Some chapters require the top to be up also unless you run with arm restraints and full face helmet with face shield.

 

breezy_rx8,

For some reason when I posted a message the system used your user name (see previous meesage). That is really strange and I couldn't delete it. This time I used the reply button instead of typing below the thread. Have you guys have this problem before? Anyway, it seems that everything is ok. By the way this is one of few forums that everyone is trying to help each other.
Cheers!
