Just a little contribution for the 1M owners. Any mistakes please let me know

///1M · 05-23-2011, 09:31 PM

Ok, I'm impressed.
How did you go about doing this?

Dan Parker · 05-23-2011, 09:37 PM

This totally explains why the 1M is so great!
Thanks much!

Dan's photos showed that the rear springs are the same (as also indicated in your diagram), and your diagram shows that the front springs are also the same.

Other reports, however, have suggested that the 1M has different spring rates due to its lighter weight.

Do we now believe that the differences are limited to different shocks and sway bars?

Thanks.

Neil

Well done! Agree with Dan, this is why this thing is so good.

I have not yet had a chance to compare the springs. From Dan's post, the rear springs appear to be the same.

Keep in mind that for each car, several springs combinations are possible depending on your options. This is why spring part numbers are not listed on online catalogs.

Awesome!

I take it this is a good thing? Aren't you a parts bin (perhaps they are from two different cultures) from your mommy and daddy?

What better car to have parts from, then the M3??

I'm not sure I follow this statement. What options are you talking about? Do you mean oem or aftermarket? If it's aftermarket I don't expect to see anything out for a little while since the car is just a few weeks since release.

rzm3 · 05-24-2011, 09:18 AM

OEM. From talking to BMW parts guys, springs obviously differ between, say, competition pkg or std suspension. They can also change based on the options you choose, i.e. premium stereo.

BMW oem spring application are taken from a master list of options to attach to the vehicle. There are lots of different springs to choose from and depending on the options, the spring rate changes..

for instance.. if you pick nav and high end stero on the same car, the springs are a different part Number, meaning they are different in some way.. It has long been discussed that the more options the more spring rate the car needed so if you want high spring rates, pick a spring that has all the options ticked off next to it.

The "M3" marked springs are from an M3, we just dont know which one ( or with which options, or lack there of )
