LSD?

[Elsabor67]

My cover is slightly different than that one. LSD is on my list, but the cost will be worth it.

Yes you are right 3.15 ratio which is a tiny shorter to oem 3.08 but car feels little more responsive (maybe it is just me) but I can definitely feel improvement in traction I would say absolutely different car it feels even more planted/stable.

Everything else, to include the pressure bleeder, I have.

all you need is another person!! i let the calipers gravity bleed and keep the reservoir full and then do the old pump and hold. works every time with great pedal feedback!

I wanted in on that LSD sale that HP Works offered in the "commercial sales" forum but it was too heavy to ship to APO.

Will take some pics. to show you guys. What you need is M3 halfshafts which goes in w/o any modification and prop shaft which has to be married with 135i prop shaft. Actually you need to find wrecked M3 (DCT) to match gear ratio. else is easy.
Here is pic during the process

Or a 1M!


Thanks for the pics Rimas. That looks very NICE, just like BMW made the car that way all along. I'm jealous.

No problem if you will decide to go that way I can help you with that. It drives really different now. I dont know why but rear is much more stable now. Though maybe I can feel a little more understeer and not sure how can I fix that maybe rear sway would help.

[FOACAD]

Could you work up a parts list and prices please??

That is very awesome that you did that. Never seen that before.

Probably more of what you feel is the 1M/M3 subframe mounts. I was really blown away on how big a change they made to my car. They improve the way the entire car handles. Not just the rear end but also in the way the front end turns into a turn. BMW really should have given us those bushings(& a better suspension) but me thinks their almighty M3 was at risk of being challenged by our lowly 1er's.

I completely agree.

Its awesome what these cars are capable of with simple suspension bits being changed out. Then add that OEM M3 LSD??? Wow....It seems like they literally took the M3/1M and then started pulling off the good stuff and putting cheaper stuff on to get the price down and the performance down as well to put it in a different category to keep sales segregated.

How much was it? Where did you have it done? Do they accept VAT forms? Would they also install subframe bushings?

Well you can do it everywhere costs is same like to replace sideshafts and differential with prop shaft + balance of the prop shaft.

Now I really believe you Don't know what to do next front M3 bits or subframe bushings?
Also at the same they did CDV delete so hell yeah now I really enjoy new car. I waited for CDV really too long.
Sometimes it is really difficult to understand BMW why they did something or they didn't but really I love BMW.

So you did not replace the rear subframe bushings when you did the LSD ?

I would do that first(rear suspension bushings). Unless your front suspension is worn out.

No I did just diff I left bushings to replace later maybe with Bilstein B12 Kit.
I guess I will leave front for now and do the bushings.
Also what about added negative camber from M3 front bits and inner tire wear during normal street driving.

That's something I have been thinking about too. As is our cars chew thru tires kind of quickly! I don't know what to suggest.

I also want to replace the rear bits too. But that will mean changing the rear shocks... and IF I do that... I will also want to change the front shocks and springs(all the way around). Humm.... $$$$

I have no idea what any of it costs, especially the M3 dif. Here in Wiesbaden there aren't a lot of tuning shops, at least that I know of. How much did the entire operation cost?
