Top recommended performance parts and accessories for the BMW M2?

Question

Honestly Ive been staring at forum threads for three days straight and my head is spinning. Just picked up a 2018 M2 and while it is a blast stock I know it needs more especially since I am planning to hit the track at Buttonwillow in like two months. I have about 3000 bucks saved up for initial mods but every single thread contradicts the last one. I read that a front mount intercooler is priority number one to stop heat soak but then half the guys on Bimmerpost are saying a bigger core causes too much pressure drop and ruins the throttle response which sounds like a nightmare.

Then there is the whole tuning thing... everyone says Bootmod3 is the way to go but then I see people complaining about spun crank hubs on the N55 even though I thought that was mostly an S55 thing? Its so annoying trying to figure out what actually matters for a reliable track build versus what is just for clout or whatever. I really dont want to blow my engine or waste money on parts that make the car feel worse to drive on the street.

intercooler (which one actually fits without cutting?)

stage 1 tune

brake pads that wont squeal like a school bus

What are the actual must-have performance parts that wont ruin the car's balance or break my bank?...

Wagner Tuning EVO 2 Performance Intercooler beats CSF, which felt laggy. Ferodo DS2500 Brake Pads outperform Hawk but stay quiet. Unfortunately, most parts just didnt live up to the hype...

^ This. Also, totally feel you on the N55 crank hub thing—it is way less of an issue than the S55 guys make it out to be! Honestly, for a budget-friendly track build that still rips on the street, you gotta look at the VRSF 6.5 inch Competition Intercooler BMW N55. I put this on my own M2 last season and it is fantastic for the price! Logged it at a local track day and the intake air temps stayed super stable even after back-to-back laps. Zero cutting required, fits like a glove, and way cheaper than the high-end stuff while doing 95% of the same job. Love it! Since you're hitting Buttonwillow soon, dont overspend on pads just yet. I ran StopTech Sport Brake Pads 309 Series for a while and they held up great without that annoying bus-squeal during daily commutes. Theyre dirt cheap compared to dedicated track pads and way better than stock. Grab some Motul RBF 600 Brake Fluid too... seriously, fresh fluid is more important than almost anything else for your first track day! Total spent would be way under your 3k mark, leaving you plenty for tires or more track time. The N55 with a Bootmod3 N55 Stage 1 License is amazing because it smooths out the torque curve without stressing the internals. You're gonna have a blast out there!
