I'm a newbie to modding and am interested in improving the handling on my car for street driving (not racing). I have a 2010 535i non-sp with a manual transmission.

1) Are there BMW parts I can use for the upgrade(M5, or Sport Package parts)?
2) What parts should I upgrade (springs, shocks, struts, swaybars, coilovers, etc...)
= goal is to decrease body roll for cornering, decrease understeer, and decrease tramlining, while maintaining ride comfort as much as possible

Also is there anything that I can do to make the steering heavier?

Any any and all suggestions would be greatly appreciated.
Thank you

Hope these help, good luck.

 

For an all-around suspension upgrade take a look at what Dinan has to offer.
