newby: drop with stock M-Sport shock

marconi118 · 03-06-2009, 09:34 AM

Drive E93 335i with M-kit suspension European version.

I don't know if tis corresponds in the states to ZSP suspension?

I would have a small drop (lets say 1 inch) in the front to clear out the bad wheel gap.

What are the best springs (HR Eibach, BMW performance) linear or progressive to use with original M-Kit shocks?

I know this has been discussed several times... but I would avoid to buy PSS10 or KV3 at least for the moment

anyone can help me?

This is a simple question:

What are the best springs to match with oem M-sport (ZSP?) shocks to have a small drop and to have at least the same handling as EOM

Ask SM at dealer. Sounds like BMW Performance would work for you, but only slight drop. Remember that you may need to replace dampers to have correct range with new springs.

the whole point is that I don't want to change the dampers.
I would only change the springs to have a drop and maintain at least the original handling

Eibach + zsp dampers = slightly stiffer ride and good handling.

Eibach will eb fine on Euro M-sport suspension. The drop isn't that much so you wo't unduly affect the opertaion of the stock shock. If you plan on dropping more then you'd need 'matched' shocks as well.

Many report Eibach to be great with standard shocks, but not sure if you'll get 1" out of them as I think the specified drop or 23/35 is over standard ride height and not M-Sport, so it might only be 15-20mm drop over all with M-Sport as its already lower than standard.

H&R have a bigger drop but this might musg you towards the limit on M-Sport shocks.
