Comfortable Ride Quality

I've read all of the suspension threads regarding XI suspension setups, recommendations, combinations, etc. and it hasn't gotten me anywhere.

I have an E92 335XI w/sports suspension and OEM 19" 313 wheels w/RFT. As expected the ride is really rough, and leaves a lot to be desired.

I'm primarily looking to lower my car (not slam it), and improve ride quality (comfort). If the car handles better because of the coilover setup I choose, GREAT. This is strictly a street car/daily driver and is driven pretty mildly.

That being said, I'm looking for the best option without going overkill. I don't need a custom built setup from HP Autowerks or AST. I've read some unfavorable reviews of the KW V1 that say the ride quality/comfort isn't that great.

Any and all advice is greatly appreciated. Here's a BEFORE photo. Hopefully you guys can steer me in the right direction and a few weeks from now I'll be able to post up an AFTER photo with my new suspension!

IMO, coilovers are overkill for street cars/daily drivers. I had KW V2's on my car last year and eventually reverted back to the OEM sport suspension because the ride was way too harsh for everyday use. It's even worse if you have shitty roads like NY does.

Eibach Pro Kit and Koni FSD seems to be the most favored combo for comfort/performance.

Damnit I've heard that too and really liked the combo, however one of the vendors said it won't fit my E93 or some issue regarding weight...he then suggest I get a coilover kit instead. *cough* upsell much?

EPK springs are great for what you descrive, they are very comfortable and perform well when paired with the right shocks.

Since you have an XI, you may want to poke around in the XI section, I now some members have dropped their cars on varous kits and I thought Eibach was one of them.

Try changing the RFT's. When i changed to non RFT's the ride quality improved significantly and it was much more comfortable.

I changed from the oem run flat tires to continental dws tires. That helped with comfort, but switching from my kw coilovers over to eibach pro kit with pro system struts, made the car even more comfortable. The coilovers made it handle like it was on rails, but i can live with giving up some handling to gain some comfort.

I gotta tell ya. I've had H&R coils on my xi for around 6 months and it seems to me that they are a great balance between performance and drivability.

I dont care what anyone says, anytime you substract suspension quality will suffer but reduce body roll and increased steering response (trade offs) The best feel would be to ditch the rft if youre asking for comfort.

Thanks for all the advice folks. Unfortunately, I'm not willing to give up the RFT as they have saved me a few times from stopping in very bad neighborHOODS.

It looks like I'm going to do more research on coupling Eibach Pro Kit springs and Koni shocks. My only worry is that there will still be wheel gap. I want perfectly flush, no tuck, etc.

Thanks again for your input everyone!
