Well here's my correspondence from BMWPartsPros. I'm not 100% what the deal is on the springs. Three different sources I get three different numbers for the performance springs. My car is a 335i Msport. FYI...messages start from bottom up timeline

You're auto trans, so you'd need part# 31336860630 for the fronts. Basically, our BMW parts catalog has a spring table and you select the M Performance Suspension option and it shows the part#'s for the springs. There is no picture that shows them being the red springs in the kit picture, and no description saying they are m performance springs.

OK, so you'd need different springs. The part numbers you'd need for the front springs is 31336860629 x 2, for manual transmission, 31336860630 x 2, for automatic transmission, and for the rear springs (for both auto and manual trans) is 33536860620 x 2. The springs are $92.40 each.

Disregard this James,
I'm now reading that it looks like you'd need springs. I'm looking into this further for you...

Hi James,
I found the installation instructions for the m sport suspension kit in .pdf format. These instructions show that the exhisting springs on your car are reinstalled when installing the msport suspension kit. There are no m performance springs or any other springs required to install the kit. So, the talk on the forums is nonsense. I am confident that I can assure you, for your f30 with m sport suspension or m sport package, all you need is what comes with the kit.
