200 cup setup is dampers, springs, anti roll bar and steering rack.
Forget the last two, only the suspensions setup will make a massive difference to handling with a trade off on ride of course. You can get a second hand kit from here, they usually go for sale and they are reasonably cheap (around 200-250 depending condition mileage etc)
Buying new is not worth it, better go aftermarket as mentalpen said but be prepared to spend more than a grand for a nice kit.
