what bushings/parts should I replace when installing coils?

I am going to be installing coils on a 2008 335 coupe next week (came with factory sports suspension). What bushings/bearings/mounts are recommended to be replaced?

I was thinking the front upper strut mount... But what else should I replace (front and back)? Car has 60,000 miles on it.

I saw this kit but not sure if all these are needed. And I can find a better price elsewhere... http://www.turnermotorsport.com/p-11...uspension.aspx

That kit is a really good idea to avoid duplicate labor down the road
In lieu of that kit: F/R upper/lower springs pads; upper/lower rear shock mounts (powerflex has hd shock mounts), upper strut mounts or camber plates.
After you get that installed you can consider HD tension links and subframe bushings if you're not riding on rft's and the car still feels soft, floaty or bouncy

For those that have replaced the rear shock mounts to powerflex, which one did you pick? They offer them in 10mm and 12mm sizes.

10mm for your OE rear dampers. 12mm is for most aftermarket dampers.
