    Bmw kinda really knows what they are doing with the factory lsd setting. If yours is worn out and your budget is limited to DIY Then just making it new Oem 2 plate spec is the best you can do.

    Oem new 2 plate configuration is better handling than 3 with free data setting; free data on the internet from folks selling subpar knock off parts is just that.

    Want real parts? Bmw and Porsche sell the real zf stuff.

    Want cheap crap; check with gayer “motorsports” or some place in Eastern Europe

    If you have a budget for a full unit build with national championship results (my local clients swept nasa National tt4 class with 1-2-3 place finish 2018, local spec Miata won overall); I can assist.

    Winning spec data will never be shared for free.
    Really don't have the budget for a full build. I can DIY most of it. Just not sure the route to take. Can measure, etc, get cap machined for a 4 clutch if it's the right direction.

        Hello,

        I'm trying to find the answer through this thread but I think that my question is a little more vague than most on here. But what i'm wanting to learn is which LSD will fill the role for the average DD while slipping out on back roads once and a while to carve a few corners up in the country.

        Just something good on the highway and street, but still have enough on the bottom to get out of its own way. The thing that is really sucking is when I try to go up a steep drive way (my house, which I don't even think about anymore lol) or an entrance to a parking lot and my coilovers bottom out and my open diff is just laughing at me while my wheel's hanging out up in the air doing a lot of nothing.

        Thank you so much!

                Assuming an un-touched original E30 M3 4.10 LSD, probably 150k-200k miles on it. How noticeable of a difference would it be to just rebuild it "stock" 2 clutch with new races and clutches? Car is for circuit use only. Sounds like this is the best option unless upgrading to an aftermarket racing unit like OS Giken.

                Also, anybody have a current link for the TIS? The link on page 1 is broken.
