Did you also do the CDV delete?

---

yeah, but i did it a long time ago. still need to do it on our X3.

the valeo SMF kit is exactly the same weight as the stock components, so it's not really a 'performance' upgrade but more of a 'preventative' upgrade. :)

LSD is absolutely one of the best upgrades - especially if you shorten the ratio to something like a 3.46. and you're fortunate to have diffsonline right next door!

I'm heading to the Great White North tomorrow so I'll see if I have one in the garage that I can throw in my bag and mail you from the hotel.

I was thinking 3.38...shorter but not too short.

3.38 is almost the same as 3.46...eh

Wish it came a bit more aggressive from the factory

i've had 3.46 for 2-3 years now and i almost wish it was a 3.64 sometimes. ;)

Crap, really? There’s a pretty clean 3.46 on my local Craigslist.

Dammit Spenser, you’ve spent enough lately!

hahahaha! a 3.46 open diff should be cheap - $150?

the 3.46 cruises nicely at highway speeds - 2950rpm @ 75mph.

Yea like $150-200. Plus another $1k for the inevitable MFactory it leads to down the road.

Holy crap! I didn't realize they're in Wilmington. Maybe I can talk them into giving me one for R&D. :p

The Mfactory stuff is definitely a lot less expensive though.

Be careful with 3.46’s. Aren’t the input flanges different? 4 bolt vs 6 bolt or something? This is something I paid a lot of attention to since I am doing a 6 speed swap. I read a few times that the 6 speed driveshaft won’t bolt right up. An auto 330’s 3.38 a different story. From my inspection at junk yards, it seems all non 330’s got one design and all 330’s got another. Some one prove me wrong?

yep, the input and output flanges are different. not hard to swap over from your stock diff. maybe 20min of work.

Fair enough. Just scary to me because there is no rated torque for that bolt. I will most likely get a 3.38 for the easy and the difference is like 2.3%. Just with my luck I wouldn’t get the input bolt tight enough. Murphy’s law

Spenser, Shawn's got a 3.38 that I believe he quite likes.

Yep. I love 3-4 gear. And 6 is awesome on the highway—not much Need to downshift at all. Great mod. Not sure I’d go past 3:46 but never driven a 3:64. It may not make that much difference at highway speed.

[QUOTE=nextelbuddy;558559]I use the 7 liter one I got on amazon warehouse deals. for $50ish dollars

takes about 5 min to pull all the oil out.

https://www.amazon.com/gp/product/B0...0?ie=UTF8&psc1

In the reviews for that pump, a fair number of reviewers report it failing and pumping oil out of the handle after 1-2 uses. Have you run into any problems?

I’ve already gone through 2 MityVacs. I’m not too impressed. They leak after a short time and the way the rubber plug is designed, makes it difficult to drain the oil into another container to take to the auto parts store for recycling. They are a waste of money.

The EWK unit I bought is much better. Better design and user interface. Easier to use and dispose of the oil.

This one?

EWK Pneumatic / Manual 6.5 Liter Oil Changer Vacuum Fluid Extractor Pump Tank Remover https://www.amazon.com/dp/B06WD64H8Z..._nANZAb1DVAMBG

ECS Tuning offers a 6.5 liter Schwaben unit for a bit more than the EWK. Looks like Griot's rebrands it for an add'l $20:
https://www.ecstuning.com/b-schwaben.../011885sch01a/

FWIW I followed amazon reviews of the EWK unit to West Marine, which apparently sells the same device but sells parts for it after the sale, which can be helpful as things wear/break (which they apparently do):
https://www.westmarine.com/buy/west-...6-5l--11047123

I think I got the schwaban one too... It's the exact same unit I've seen on several sites but they had the cheapest price at the time. I use it on our boat....

Does anyone know why this happens??
It happened on my E30 as well so it's not limited to just my ZHP...https://uploads.tapatalk-cdn.com/201...6f0cadbaf1.jpg

Soaking wet (at the car wash) yet there's this unexplicable clear patch...

Isn’t it rubber residue left behind from the wipers? I think that’s what I read/heard somewhere. Idk, I haven’t used my wipers since I discovered RainX like 12 years ago.

Is this a statement or a question? If it's indeed rubber residue, perhaps I need to scrub-a-dub-dub my windshield with some rubbing alcohol or something...

Great for highway, but not so much for around-town. :(

I relate it to when I still had glasses; the smallest particles of dirt on the lenses would drive me nuts! Around town isn't going fast enough to make those water beads slide down fast enough.

I got a surprising amount of life out of using a synthetic sealant like my Menzerna PowerLock on my windshield back when the car was actually detailed. It behaved just like RainX on the highway, but around town, it would stand up to the abuse of the wipers being on. It lasted months this way.

You can use a mild clay bar (along with soapy water or detailer spray) or 0000 steel or brass wool on your glass to remove contaminants.

It was a question and a statement. What I meant was “I think that’s caused by rubber residue.” Sealants/RainX work well for me “around town” because I’m in the suburbs. I can easily achieve speeds capable of getting the beads moving. As John suggested, start with a clay, and proceed with something more aggressive as needed.

This. I’ve never been brave enough to use quad-aught steel wool, but I clay the glass twice a year.

I been using fine steel wool since the seventies... it's safe

Yup! That’s the one. Very easy to use. It works much better than the MityVacs and versatile.

I changed the AC pressure sensor and all the refrigerant blew out (all over my hand and front of the car :facepalm ). Do I need to vacuum out the system now, or is just a regular refill ok?

Yes it needs to be purged of all air in the system by vacuum.

dang. ok thanks.

Would it be stupid or cool to take off the 330i badge and put on one that says "ZHP"?

Personally, keep the badging or maybe even debadge, but I’d avoid the ZHP badging.

Just my $0.02

Can anyone post the vert ZHP specs/options? Or, does anyone know if the 06 verts came with the alcantara steering wheels and boots? Thanks.

Question from our FB page. I wasn't sure.

Do whatever you want, dude. Could be cool, could be goofy. Up to you to decide if you like it. I thought about doing the same thing when I got the red car.
