Discussion
No expert I'm afraid but the GT2 cars are allowed more modifications to bodywork, engines, suspension, brakes etc. than the GTC cars. If you go to a GT round I found the Avon booklet they gave out at Oulton quite informative. Unfortunately don't have mine to hand to give what it says in there.

BGT site said:
The 2006 Avon Tyres British GT Championship is open to cars in four classes –
• GT2 – open to cars homologated in the FIA GT2 category or Grand Touring cars produced in small numbers and eligible according to the organisers file.
• GT3 – open to cars that strictly adhere to the FIA GT3 Regulations
• GTC – The basis for this class are the specific regulations for the single-make cups, & the characteristics of production cars amended by the points mentioned in the championship technical regulations. Any modification to the car is forbidden if it is not specifically authorised.
• Invitation class - This class will be for cars, selected by the organisers, which for reason of homologation, production numbers or other reasons do not comply with the regulations for GT2, GTC or GT3.
What is the definition of a Grand Touring (GT) Car?
A closed automobile that has no more than one door on each side, no more than four seats, is fully legal for road use & has been modified to ensure suitability for speed races on circuits or closed courses.
Class Numbers
Cars from each class can be identified by the following coloured system for the number panels on each car.
• Black numbers on white backgrounds GT2
• White numbers on black backgrounds GTC.
• White numbers on red backgrounds GT3
• Black numbers on Yellow background Invitation class.

GT2 cars are what were originally (way back when) GT3 cars. So, you're Porsche GT3 R/RS/RSR, Ferrari 430 (new model) TVR T400R, Mosler MT900R, Panoz Esperantes etc etc. Are you with me so far??
Good.
GTC, is the GT3 class for the British GT Championship. However, they can't call them GT3 cars anymore, as the FIA have launched the official GT3 championship, which runs cars homologated to GT3 (Think, Aston DBRS9, Porsche 997, Corvette C6, Dodge Viper) but they're not as powerful or as race prepped as the GT2 spec cars (and nowhere near a GT1 spec machine) The cars that run in this class are things like: Prosport, Morgan, Porsche 996 (Cup car), Marcos Mantis, etc etc.
There is a GT3 class in the British GT championship, which is there for most up to date cars, (the same that run in the FIA GT3 championship) there are Astons, a pair of brand new Lotus' and a couple (I think) Porsche 997's at Donington.
Does that make it more clear?

Sorted, thanks.
I understood the distinction between GT1 / GT2 / GT3.
It was the GTC that started to confuse becasue it seemd you could enter the same car in GTC or GT2, but now I see it is the spec of or modifications to the car that dictate where it should be competing.
So clearly GT2 will be quicker than GTC, but where will the 'new' GT3 cars be against the GTC cars?
GTC is run to a strict power to weight ratio, (0.24Bhp/Tonne - BHP being at the wheels accoring to G-Forces RR in aylesbury, and wieght is the car + the average of the two drivers)
GT3 is basically being 'engineered' to level out performance by specific limits/mods to each car entered. the basic target is to equalise performance to the level of a factory stock 997 GT3.
where GTC and GT3 will stack up is hard to say, but in theory, GT3 should be faster.
In Brit GT, 997's are not alowed in GTC, and I can't see the 997 being slower than the 996
