I think quality of PSS9 is better than V2 ... When I was installing mine PSS9 this guy brought his M3 with V2 and cracked rear spring. It took him forever to contat KW to get a new spring ... + cheaper is not always good !!! |

sounds good guys! yea i kno comfort is all relative, i should have said as comfortable as stock haha. so its my understanding that both of these can get as comfortable as stock ride with the benefit of lowering the car and having better handling right?

Even though there are already quite a few useful opinions here, I figured I'd chime in on my experience with both. I agree with both opinions, that Bilstein is more comfortable yet KW offers a more economical option as well as a stiffer and lower ride.
Ultimately, it's up to you whether you want comfort or ride height, but as most people don't track, I'd opt for comfort unless the ride height difference is really that profound. Also, I've had or seen issues with KW V2s, both old and new versions. Blown shock cylinders within months of installation, rattling housings out of the box, etc. KW support is also very poor and unhelpful. The Bilsteins will put you as close to OEM ride quality as almost any coilover setup, especially the stiffer, harsher KWs. |

Unless you are hardcore, go with the V2s, it is the best bang for the buck.
I sell both PSS9 and KW, but if you had to ask for my personal preference, I would go with KW over PSS9s any day. -Don |

Sometimes a softer rear spring rate provides better overall handling that going stiffer. The E90 chassis is very sensitive to rear spring rate adjustments. 400 front and 400 rear is a more compliant ride. Also remember that the shape of the spring determines to some point the ride characteristics as well. The Stock spring, TCK's and the KW is consistantly wound at the same interval. The Bilstein is wound like a progressive and/or tender spring in that the top 1/3rd or more portion is basically coil bound and takes up the slack at full droop and only the bottom section is working with more space between each active coil than the others. Also TCK's front springs are linear and each coil is equally spaced vs. the standard pigtailed spring that the other kits use, which also affects handling behavior.

wow thanks for all your thoughts guys. Yea the comfort is what matters the most to me so i'm leaning towards the pss9's. i had heard originally that the kw's were softer but seems like thats not the case. Price wise it seems like a few hundred bucks difference so thats not such a biggie since I dont want to compromise the quality and comfort of my 335. Thanks again!

My 2¢ -- it's a mistake to go lower. Especially with lower profile tires. You are very likely to have big suspension geometry problems. If you want KWs for spring rates or whatever, fine, but lowering more than the max possible on the PSS9s is unwise.

I think I will go with PSS9s. My car rides so smooth now, I just want it a bit lower (eibach height), and better handling and I will be a happy camper. If I can get stock ride comfort, I will be happy.

Don't forget to write up your experiences after the installs. We need more data from members on how their suspension mods are working out.

no problemo, I will definately keep you guys posted. There's a group buy here somewhere (sorry i dont have the link) but its for KWv2's so i'll see how that goes, because it seems like pss9's and V2's are basically the same price.
