Yes they are. If it came in the model box-stock, and hasn't been modified, and the car isn't some 1 of 10 competition special, then it's legal.
Clutch-type LSD's are used in Mustangs, Camaros, Trans Ams, Thunderbirds, RX-7's, and more, all of which are legal to race in the ST classes (STS, STS2, STX, STU).

The RB header is not legal at all. It removes the precats which are just as illegal to remove in all 50 states as the main cat. The only thing is that most people have never heard of, or even seen a precat. And I'm 80% sure the factory un modified GSL and SE equpied cars can run in ST. You just can't swap a GSL or SE rearend into your base or GS.

Which leaves the choice of if you want to run C-Stock, CSP, or higher.

Do you have any example cars doing this (Specifically looking for a GSL-SE)? The rules state that the only LSD's allowed are factory viscous ones. Since the GSL-SE has a clutch-type diff it is therefore excluded from the class, correct?

Exactly. We (GSL and -SEs) are legal for the new STR class though with our LSDs. Might not be competitive with S2000s, MR2's, and decked miatas though. I don't see the FB being CSP competitive either. Even though two members have done it at a local level, I really don't see it happening on a national level. However, a fully prepped SM FB could be very interesting.
(kencunm and I are trying to decide what we want to prep our '85 GSL-SE for next season.)

I am currently running SSM in my RX-7.
If you look at the national results it places us against everything from a Ferrari to a Turbo Miata running 275 width hoosiers (I am friends with the owner). On those Hoosiers he runs about 3 seconds faster than me on my 205 NT01s. Locally you are likely to run into well prepped corvettes. Until I turbo the car, flare the fenders and start running 355 slicks I doubt I will be any type of competition. It is a tough road to hoe.
