    Thanks Will. Do you know how much the drop is from stock? Do you mind posting or sending me a picture of the stance?

    Local shop recommended H&R Sports at 182/343 with 1”/.75” drop. Not sure...
    J stocks are 640/1080 lb spring rate. They are awesome, don't bottom over every little thing and aren't harsh. Yes they are firm, but I've done 22 hrs straight on them (yes at one time) and it wasn't a big deal. HR Race springs are WAY too soft for, well, anything. (Been there, done that.)

    I had the HR Race on my old M3 and it was good on the street. I have J-Stock on my current one. It is 95% time a track car but I will drive it on the street to an AutoX if I am to lazy to load the trailer and it isn't that big of deal.

    Yes but you need to know the "target" to get the magic setup turner came up with. In reality you can valve anything you want any way you want, just send your set to bilstein and they will do it to your spec.
    Another fella on here (rad2ltr?) has his setup with tc klein (revalved konis) and he loves it. So you really don't need his dampers unless you want exactly what turner specified.
    Make sure you indicate you would want more than one set of springs on the spreadsheet so Will knows how many to include in the batch.

    Edit: my understanding is that many who revalve the b8's and use them with lowering springs (i.e. jstock) will also cut their bump stops in half.

    I updated the spreadsheet with a new column since it was a little confusing if people would flat out not buy the springs without the billys. It's just a YES/NO column if you would buy the springs even if the billys are unavailable for the foreseeable future.

    Bad News friendlies. Looks like the dampers may be a no go for a long time. Will doesn't seem to know why either so I am now going to need to see who is willing to purchase just the springs without matched dampers...

    I will be for sure - I'll be able to find something for dampers that will work great based on other comments on the forum from users who have had success. I think Will is worried many who want the springs only want them on the condition they get the dampers too. Hopefully that's not the case but if so you may want to indicate on the spreadsheet (page 1 first post) if you are "Only with dampers" or "with or without dampers" or some such..


    If you know someone on the list who isn't on s14 please let them know.

    Looks like the B8's are starting to free up again. First batch coming over won't be JS stuff I'm guessing there are back orders to fill etc first. Good news nonetheless, making progress.

    Definitely understood.

    If it's going to be a both or none kind of deal I think I'm going to pull my name off. I can't stand Bilsteins- they ride like ass in everything I've used them for from custom valving to a simple h&r/bilstein setup. They're true inverted struts which I'm sure is why he likes them. Konis just ride SO much better it's not worth the negligible difference in handling that 1% of folks running Jstocks will take advantage of on the track.

    This means everyone is at the mercy of Bilstein.
    I called a NA rep and he said they were changing the tooling out and it wont be until September before they catch back up...
    Who knows if that's accurate but its all ive got from Bilstein.

    Maybe you can get better info being in Germany, the NA people prob don't actually know the real issue
