nvrm, just called Dan and here is the other number, 33 53 6 788 905. Just put my order in. They are going to be used with my Bilstein Euro Sport shocks and Eibach Sport kit..AKA Bilstein B12 Sport kit in Europe. Very glad i found your thread cvc 22349a!

I have the original BMW performance springs, the black ones, with Koni yellows, but I'm not sure what bump stops I have. Since I had the original performance dampers before getting the yellows, I must have the original V1 bump stops?

Should I consider getting the V2 bump stops?

I know you've had the PS for a long time Fraggy, so I'm guessing you have V1. I didn't know PS springs were originally black, so I have no idea what the configuration should be. Maybe check w/your vendor or Tischer? If you put your car on a lift, you can look at and measure the bstops.

I haven't looked at them in a long time, but I think the springs are labeled D4 both front and rear. Do the yellow springs carry similar the same designations?

My PS springs are both labeled T4. My sport springs are D7 and D5

Probably T4 then, like I said, Ive not looked in years. I just knew it was a four.
