Slavik's 2002 Carbon Schwarz M3 6 Speed Build

EPIC Journal !!!

Thank you for the write up. I have to be honest, I am feeling pretty inadequate right now 😦

My journal is the equivalent of a few average detailing sessions 😿


And that under carriage care, I love that. I have a total fetish and watch all the reddish motor sports under carriage rehabs . . .. https://www.youtube.com/watch?v=yAzyc8S6boE


Totally following!

Lots of nice work going on and very satisfying to see a clean and rust free underside!

All of unnecessary wiring has been removed which nets a 5 lbs. weight savings:

Started to tinker with the wiring today...

I will be de-pining all of the options that I do not want on my car. The first to go was the speaker wiring and side air bags on the doors.


I plan on removing the following options from the 06 M3 SMG wiring:
-SMG wires
-SMG hood lock wires
-Sunroof wires
-Secondary air injection wires
-PDC wires
-Door air bag wires
-Heated and power seats wires
-Any audio wiring that is left on the main harness


All of the wires will be weighed at the end to see how much weight was saved.

Did some dirty work over the weekend...

Got out the P21s, a brush and the pressure washer to clean out the underside and engine bay of the chassis before I start running the wiring and subframe reinforcement.

More parts arrived...




Going with CMP's solid bushings for the rear and Stealth Vincebar (weld-in version).

Had some time after work today to pull out all of the wiring. Even got around to removing the sunroof. It will not be making its way back...






Next on the list will be a good wash to get out all of the dirt and debris before I dive into the top subframe reinforcement.

The FM LSD thing is about finding the sweet spot for your car where there's enough FM in the lube to keep it quiet and not be so touchy, but not so much that it allows the clutch to just slip too easily. It's not about the brand or even which chemicals that brand uses. It's just about the quantity you need to reach that point.

It's hard to know if the OE fluid, with the FM booster, is the correct amount. It does seem to quiet everyone's down, but how do we know if it's allowing for slipping? I used the OE fluid (sans FM booster), much cheaper, then added in "Lubegard" LSD FM (great brand). I actually stopped at the point where I could still just barely hear some groaning on a tight turn. Just so I knew it was still grabbing hard.

Since I couldn't get on top of my overheating issues, I decided to park the car for the winter. Big plans for the winter. First and foremost, I ordered myself a weld in stealth VinceBar due to the fact that my reinforced RACP started to split. Next on the list was a project that I am really looking forward to. Picked up a complete wiring harness from a 2006 M3. The purpose of this is to do a Mk60 conversion. All parts came out of a low mileage SMG M3. In my pursuit of lightweight, I will be pulling out all of the unnecessary plugs and just leaving in what I need. To finish everything off, I will be fitting a set of Porsche brakes with PFC V3 rotors.

The progress so far...









Waiting for the weekend to swap out the harness and remove some other parts. A full under body wash is in order prior to assembly.

Thanks for the input. I also read that adding some Redline friction modifier may quite things down but the draw back is that it clutches don't grab as well? Any thoughts.


I did have a set but I got rid of them for emission reasons. The ones I had were catless. This time ECS had a good deal on cats and headers.

I'm partial to only OE fluids in this car. I haven't heard of the clutches not grabbing as well with Redline in the diff but the M Variable unit struggles with OE fluid too. Luckily there are many companies that make "plug and play" clutch packs with more aggressiveness to them for you.

Very cool to see! Since the wall is thinner, if the csl one has at least the same OD, than the ID would be slightly bigger. Not much, but maybe a couple of ponies :P

Are there any differences between a stock OE section 2 and the CSL section 2, aside from weight savings?

Nope, weight is the only difference between the two.

Packed up some necessities and went for a camp/drive to Virgina/Tennesse:




Originally, planned as a three day drive (Friday to Sunday), but ended up as a two day because my brother ran out of front tires. All in all it was an awesome trip. We put in 535 miles round trip with both cars not skipping a beat. I couldn't ask for a better weekend with temperatures being upper 70's/lower 80's and no humidity.

REM polishing the diff won't do anything. My Dinan diff is REM polished and it whines like crazy on accel and decel. I have different clutch packs tho.

Thought you already had SSV1s installed tho?
