GT12 BRCA Kit Price limit?

[G2510]

Hi All,

I apologise if this has been asked before or a number of times but I am looking at my first GT12 kit and like the look of the kits from Mardave (assassin), Zen Racing and Schumacher but the kits are all £160+++. BRCA rules state the kit should not exceed £99.95

Whats the deal here, are these cars not BRCA legal?

Sorry if this is a silly question with an obvious answer I have missed
