E90 M3 DCT Stripper (Slicktop, Clothseats, Single Hump) Build Journal
hello all,
recently picked up my E90 M3. Let me first start off by saying that this is my favorite "M" car to date -- and that is coming from someone who has driven nearly every model, and generation BMW / "M" car. I only see myself selling this car to fund the purchase of a 997.1 GT3 / 964. Spec: Alpine White Slicktop Cloth-Seats No Navigation No EDC DCT Rear sun-shades Titan Shadow interior trim (my favorite!) Current modifications (as of purchasing the car) - KW Clubsports - Cool Carbon front & rear brake pads - 82mm MRG Titanium wheel studs - EAS black grill - EAS painted reflectors The car's story: I'm the third owner of this car. The first owner was presumably in the Navy, and ordered / took delivery of the car in Germany in late 2009. Once delivered, he drove the car in Germany for the first three years of ownership, until it was imported into the states in late 2012. He then continued to drive it for six more years, until trading it in for a newer car in 2018 at BMW of San Diego. The second owner purchased the car from BMW of San Diego in 2018, and put ~13,000 miles on the car in his two years of ownership, adding on tasteful modifications along the way. PPI: Several days before purchasing the car, I had the car inspected by Funfzehn. I received the following results: The results were a little worse than expected, but not horrible. Oil seepage from both valve cover gaskets, and some seepage by the DCT pan -- in addition to collapsed engine mounts. From what I was told, this is to be expected in a car nearing 100,000 miles, but I would like to get these items taken care of sooner rather than later. I plan on having the rod bearings, engine mounts, and trans mounts replaced ASAP (at, or before 100,000 miles.) The drive home: Overall the car was really solid for the ~800 mile journey home. At 75-80+mph there was a slight vibration in the steering wheel, apart from that, everything went flawlessly. Before leaving, I taped up the front of the car to ensure that I wouldn't pick up too many rock chips. The car preformed great, and oil temps stayed around 210-220 even in 109 degree heat. After ~500 miles, the tape started to tear off...I'm just happy it even stayed on in the first place. Home: I plan on taking the car into the shop today in order to have the recall done. I also plan on having the tires balanced and re-mounted...curious to see their road force numbers. Plans for the next few months: - I first plan on raising the car in the rear, so that the rear height matches the front. - Hotchkiss front & rear sway bars - Fall-line adjustable front & rear sway bar end links - alignment / corner balance at new ride hight - rod bearings, engine mounts, and transmission mounts - valve cover gaskets, and spark plugs That's all I've got, for now...please bear with me while I figure out the best way to upload my images.

Got my car aligned, and corner balanced today. I also got my tires road force balanced -- which killed the vibration I was experiencing at 75+mph.
My previous alignment was pretty messed up, hoping for the best with the new setup. Road force numbers look good, besides one which is at 23lbs. Surprised how well these tires have held up. Not bad! Last edited by 911r; 07-08-2020 at 07:45 PM.. |

Parts are starting to roll in for my 100,000 mile refresh. I decided to go with MRF Engineering to install these parts, in addition to doing rod bearings and his famous solid rear subframe bushings.

What's that mean? How does that reduce the risk? Also, you should very strongly consider ditching the titanium studs. Probably fine for the street but do not track the car on those.

The E92 M3 GTS for example came with 5mm spacers in the front from the factory, in order to clear it's KW Clubsports — the M3 GTS also has wheel studs. When I start tracking the car, I will be ordering a set of MSI studs from Bret Slicer. Titanium studs aren't ideal, but for the street they should be fine. |

As mentioned above, measure carefully. The 5mm spacer is likely reducing your hub from 9mm to 4mm. If the inside of the wheel has additional chamfer you're likely resting on even less. Consider chatting with BW, Apex, or Turner. The MSI studs are excellent! Good luck man and enjoy the new car.

What are you planning to do for your differential bushings?

According to my measurements, a 3mm spacer still leaves about the same hub support as no spacer because it only reduce the amount of tapering the hub has for convenience. The 5mm actually take away support. Ok for a show car, but I concluded that it won't be enough for a track car. YMMV |

The wheel cannot rest on the studs. The holes are bigger then the studs. |

Damn KW Clubsports! Wish they didn't have this silly fitment issue. I wonder how BMW was able to successfully & safely use a 5mm spacer on the GTS, among other factory track prep'd cars. |
