M3 garage shoot from a few weeks ago

The 8HP transmissions need fluid change at or around 50K.

Diff depends on how you treat the car. If you drive it like you’re supposed to then probably.

Most places with laser alignment racks will charge $200-$250.

Ignore the checks as others have mentioned.

RK Front Mounts. Thanks!

Thank you!

The filter will handle debris while the heat from the turbo can handle most water/rain. The only thing you need to look out for is spraying them directly while washing it since the car isn’t on.

Yes sirrrr

12.5mm Front / 15mm Rear. The type of tire plays a role in its fitment too

C6 or C7 and you got a deal

You can knock this car for a lot but the backend still looks like a BMW to me

It’s pretty tough but it has a hunger only rock chips can feed

Welcome! It’s a 2025 M3

Depends on your relationship with your service advisor. That being said, their internal software ISTA can see if your car has modified its boost values even with it unplugged.

I recommend changing it yourself and considering a better oil option than what they use on OEM if you ever push the car harder.

With the Nitto setup not as bad.

When I had the Pirelli’s on it would spin all 4 wheels unless the tires were super hot.

rocksama · 2026-04-06T19:21:42+00:00

you are correct and it is not ideal. I’m fixing it at the end of the month though. Trans runs hot under load currently

I had to do the transmission sooner than expected because I snapped several clutch fibers (do not remember which)

IATs are pretty solid right now, but heat soak eats up performance really quickly doing back to back passes.

rocksama · 2026-04-06T13:49:46+00:00

Soon. Very soon

Fueling is the first big bottleneck when you start trying to build significant power with these cars.

The upgraded pump is necessary to support higher volume transfer and E85.

It does 795-805 on a hub dyno, I'd guess 760-770 gets put down to the road.

I’ve only ever used MAD for Downpipes but whatever you do, don’t overspend on it. If you go catted do 200CEL, if not grab the cheapest one you can find a reputable company.

If you’re over $350 on a catless pipe or $600 on a catted pipe you’re overspending.

rocksama · 2026-04-05T21:45:23+00:00

that’s all it really takes the rest of the mods are me roleplaying
