Bought a CPO 335i with no sport package
, love the car but am not crazy about the suspension setup, it's too "floaty". To make matters worse, I bought a SSTT and the suspension is definitely not up to the task of handling the extra forty HP. Any suggestions on what suspension setup I should go with? I'm thinking of doing a sport package retrofit but don't know how much it'll cost and what parts I'll need. I'm also hearing that the BMW performance setup is great. Any help would be much appreciated, thanks!
