What did you do for your M3 today?

That's going to take me a bit to write all of this down. I'll make a thread on it soon. You're making me work 😅

I am curious to know the details. I’ve built several E46 M3 Track cars/race cars in the past but they all had roll bar or roll cage. Here is the last one I built in 2020, chassis completely stripped, stitch weld, … There was still room for improvement tho

Holy shit, that is really light!! We need more details of the weight reduction please. Pics of the interior and engine bay please!

I will build my TiAg M3 this winter and want to get it as light as possible for 2025 track season.

Picked up my car yesterday after having it in for suspension setup. First time I've had it on individual wheel scales since I threw out most unnecessary stuff.
I was really surprised when I saw the total weight at 1166kg (2565 lbs). Finally a positive surprise. Still got the air blower in, glass windows, and steel doors. So there should be some more potential 😅

What’s your oil of choice? I run Liquid Moly 10W/60 in the black M3 so will likely do the same with this one. I’m of course going to send an oil sample to Blackstone to see what unknown damage might be lingering and also… what type of oil has been used in the last 15-20K miles.

I use M1 15w50.

Complete the Catch Can in the cleanest way.

These came out 10/10. Real leather with the M touches almost makes me wish I went with these over my PP.

PP is a way better seat and much lighter.

New seats with custom seat mounts and momentary switch. Details in my build thread HERE

Ugh, I kind of suspected that when I removed the original fan clutch and it didn't spin freely or easily, just like when I assembled the new one. Ok, I'll continue to search for the real problem. Thanks!

Did you install the fan in the correct orientation to the fan clutch? I made that mistake and a forum member caught it for me thankfully before I installed it. Just a thought!

This is mine at 43k miles (before) and at 53k (after). Just oil changes every year, which is about 2-3k max.

So clean that it looks dry 😮

[maupineda]

Yes, looks low quality and probably hasn’t been changed in well over 10,000 km. Once I get the appropriate valve shims (nearly all of them were out of spec) I’ll flush the oil and run a cleaning agent for about 2,500 km and then change the oil again.
