You need to check your region rules, but most likely if you make ANY changes that are not a stock or factory option, it will boot you out of a stock class and put you in a prepared class

I know in Zone 8 where I am, it would need to be a N. American option, not a ROW option in order to stay in stock.
Of course our zone decided to change the tire rules to something that is idiotic for stock, you can run a 200TW tire if it is a N spec, or any 201 or higher tire. Nothng lower than 200 TW even if N spec , even if it was a factory delivered tire.

We run a point based system we cal CC class and there are points assessed for things like Tire TW, Tire width, springs, sways, camber plates, pretty much anything that improves (?) the performance of the car. Your total points determines what class you are running in. With this system, you can have a variety of cars in the same class, like 914, 944, old AC 911, 986, 986, 981, 996, 997, 991 928, you get the idea, could all be in the same class depending on how that are setup
