I have not been reading these updates in the Fasttrack section, but I can
see where this is going...
I don't have any problems with a lot of the proposed changes - we are
after all talking about safety. However if some classes are allowed to
look the "other way" than that is not at all fair.

I've visited that site. They have the car class pages (Appendix A of the
Solo II book), but that's about it...
If you are going to play SCCA Solo II, you should get a copy of the rule
book. If you go to an event (regional or national level) and someone
protests you, if you don't have a book, you automatically default the
protest - even for a bullshit protest.
- like the time a bunch NER folks painted their valve covers black. It's
not stock, but is it a violation? No book - you loose.
On the other hand, if you're doing this for fun, then just put in a roll
bar from Autopower and go play.
I also have news for you. If you do build a cage that is fully GCR
compliant (whatever that means), then your TR6 will be so stiff that
you'll have to play with all of the spring rates to re-balance the car.
Remember that your suspension is a _system_. Everything is a trade-off or
a compromise. Changing the stiffnes of a Triumph will change the
handling. It might make it better, but it will effect the balance.

If you are going to do the DSP thing, I would not replace the rubber body
mounts with aluminium blocks. Any person worth thier salt would be able
to determine that this would be a performance enhancement and thus
contrary to the spirit of the rules. However they would also problably
protest lead or other heavy metals too... go figure.
I have no idea what would be legal in A Prepared, suffice to say if you
go to frame extentions and so forth - you'd better make sure that it is E
Prod legal...
I'm not sure what the GT1 references are too. If I have time in the next
few days, I'll have to dig through the old Fasttracks and try to make
some sense of it. However, if I don't find any references, I'll
capitulate and try to find some safety scrutineers in my region and ask
them. Again, as I said yesterday - you need to keep asking around because
the answers that you get will vary quite a lot. If you plan to run in
your region, talk to others in your region...

This would def. move you into Prepared or Mod class. This would not be
DSP legal. However this is exactly what the E-Prod guys seemd to be doing
to the TR6's that I looked at when I was at the runoffs. The cage that
Sam Halkias has is a real work of art. FWIW, he uses the cage as the
mounting points for the coil-over shocks and the rear roll bar... his
"new car" is really trick. Too bad that he had to run his backup car for
the "big race".
For those other classes (Prepared and Mod) you can always play the "it's
a safety issue" for the frame extensions etc.

Me niether, and I'm starting to wonder what I'm getting myself into.

You're welcome.

FWIW, there's a GT3 TR6 in the New England area for sale - $8500 with
"tons of spares". Too bad my wife got all the money in the divorce.
Anybody got any spare cash???
