Hi all,

I have an '09 335i sedan with sport package, and the rough ride over city streets is starting to get to me. I think an upgrade to Koni FSD shocks might be the answer to my problems, but need some advice. Here are my questions:

1) How much should installation of a set of FSDs cost? I've read a couple threads saying that it shouldn't be more than $300, but my local shop just quoted me 4-7 hours at $140/hr (not including an alignment after).

2) Can someone recommend a good shop in the SF Bay Area that could handle this at a reasonable price?

3) Will there be any demand for my old sport dampers? They'll have less than 30k miles on them. What should I ask for them?

4) I plan on keeping my sport springs on the car. Is that ok? Will I need to shorten the bump stops, and if so, will that increase the risk of the wheel contacting the wheel well?

Sorry for all the questions, but I know nothing about this stuff. Grateful for any advice you guys can provide. Thanks!

I ran fsd's with sport springs for a couple years. Better comfort and handling than the oe dampers. You won't need an alignment or different bumpstops. Sonic MS in mtn view is a great shop. You won't get much if anything for your oe dampers.

Thanks for the info. How much did you pay for installation?

I paid 200 to have mine installed here http://www.yelp.com/biz/sleek-motoring-mountain-view

They are cool people and I trust their work, you can read the reviews yourself.

I'm really happy with my FSD's. Its more comfortable for sure, and I've driven in SF with my car, so I have first hand knowledge.

I would check alignment after changing shocks. Really any chassi work should be followed by an alignment eventhough you are not trying to change the geometry at all.

4 hours is about right. Labor rate can vary from as long as $60 an hour to $180 an hour depend on where you live.

Keep them as you may never know when you need some OE dampers.

4) I plan on keeping my sport springs on the car. Is that ok? Will I need to shorten the bump stops, and if so, will that increase the risk of the wheel contacting the wheel well?

Your OE bump stops are fine, no need to upgrade.
