Hey gang,
I'm new to the e90 platform, but think I've finally settled on a suspension that gives me what I'm looking for. I've got a 2011 335xi, so I'm fairly limited, and due to the crappy roads, the need for a high WAF, and cost, I'm going with the Koni Sports + Eibach springs.

Are there any OEM parts I need to pick up to do the swap? Bump stops, nuts, stretch bolts, washers? The car only has 22k miles, so not much wear so far.

Also anybody got a source for Koni/Eibachs as a package, I'd appreciate it.

Thanks,
Scott
