Might need different threads for these questions but I’m also trying to figure out if the sport brake master cylinder will fit my 2010 g37x brake booster. I’m finding a few different part number but each one says they fit all models.

Topics split and moved to correct forum. You were correct in thinking those questions should be separate topics. Splitting them up will help others who my have the same question, and will make it easier for them to search for an answer.

As for parts numbers, I use https://www.infinitipartsdeal.com/ as a reference guide.

IPD may not help you directly if there are different brake setups used in the same MY, but chances are if the masters are swappable then there will only be one booster part number for the entire MY. You may be able to use that to find out indirectly. Enter your car generically (by model and year) instead of VIN and IPD will show you all the possible parts used for that MY. If it only shows one p/n (or one series with supersessions) for boosters then it's likely any master from that MY will bolt up.
