Brembo Brakes for my 325i

I have found two listings for Brembo calipers meant for a 380mm 370mm setup. I currently have 300mm brakes and want to put them on but am unsure of clearance. One is from redline (blue one) and the other is from FCP Euro. I want to try to get one of these if they fit because the alternative is going to a Brembo authorized vendor and probably getting told “we don’t have brakes for your small rotors.” I’ve seen ppl do these kinds of conversions and I’m looking for advise.
