Not A Project: Peter’s 2009 335i M Sport

OS Giken Super lock. It's got 28 friction plates in it. Vac Motorsports installed it. We used to live near them. The ring gear is welded on the diff so they cut it off and machine it for bolts

i hate the welded bit. i understand it was likely done for strength, but it still pisses me off.

That uniquely appalling stench of used gear oil would be a notable downside for me *

yeah. it's nasty. especially in your beard. you just gotta shave that business off... there's no cleaning it out.

Had my mechanic take care of it when I bought the car since he was doing a number of other things. I heard the car start and pull into the garage bay while I'm sitting in the attached waiting room. Immediately stunk up the garage with the catless downpipes and not 5 minutes later I started smelling burnt corpses. Yep that's the diff fluid alright.

LOL!!

I thought it was 12k...

even still... that seems crazy.

i'll likely go with another helical LSD, they suit my needs (i don't want lockup on decel).

12k you're right. I just checked my build thread again

in the next episode of As The Turbos Spool....

one of the rear wheel bearings (sounds like RR) is starting to get noisy. 81K KMs (~50K miles). way too early. ordering a bearing (or two) this week.

Make sure the wheel bearing plug is plugged in first before you order one.

LOL!! thanks man... you may have saved me some serious work.

picked up a 41K-mile 3.46 diff for the 335 yesterday. it's supposed to have a bolted ring gear, so i'll find out once i drain it and pop the rear cover. they only made the bolted, large-case 3.46 for like 1 year, so if it is what i hope it is, it was a good find.

short term plan: drain, open case and inspect, reseal, install w/ new fluid, and see how the 3.46 is (stock is 3.08).

long term plan: send the 3.46 out for LSD install. MFactory (curious about the group buy), or Wavetrac. would prefer to try the Wavetrac this time, but price is a major factor. i've also been thinking about installing the LSD myself if it's a bolted diff - doesn't look too difficult. would save me some money.

after a long drive home from toronto in some sketchy weather last night, LSD is higher up my 'must' list. i need more grip in this thing.
