I am doing Swift/AST coilover but I am on the fence with what spring rates to run..400/800 is what is recommended by Harold..but I was debating going a step down to 350/700 for comfort reasons..live in NY and worried about driving on bumpy roads.... Can anyone comment on spring rates set up and how it feels on the street? |

I just installed KW Clubsports on the weekend.
I love the ride, it's slightly firmer then stock but with a more planted road feel. The coilovers are able to process all the small bumps and road irregularities alot more easily, thereby feeling more comfortable. I've had V1's and V3's, and I feel the Clubsports would do fine for my use if I decided to go to the track or run stickery rubber. |

I am curious..does KW Clubsports run progressive or linear springs..The spring rate sticky says it use 400/570 frnt/rear spring...Curious how it feels in the rear b/c thats a lil smaller spring rate than most of the other coilover systems in its class..

They are two diff coilover systems offered by KW..KWv3 uses progressive springs and they are dual adjustable, rebound and compression.
Clubsports I believe use linear springs (not sure) -w/ 400/570 spring rates also not sure if they are single or double adjustable. |

I have done much research and have talked extensively with Harold at HP Autowerks, so I have a good idea of what is best. I have the KW V2s on the car atm and at some point I will 100% go with the swift springs. They are quite unbelievable in their versatility between street use and track use. The KW springs are really nice for everyday driving but they are quite incapable at the track. It is cheaper to get shocks with the springs and build your own kit than buy KW and do the swift conversion (although it is a VERY good setup).
If I had to do it again, I would have gotten koni shocks with swift springs or AST coils with swift springs. Here is an added commentary on the swift springs by my buddy Tyler. http://forum.e46fanatics.com/showthread.php?p=11994300 Good luck!!!

Keep in mind, KW's valve technology is far superior then the rest of the other coilovers out there. Their philosphy is running a softer spring rate and let the valving do its work. - in the majority of cases. This setup produces a more easier and predictable setup for driving and usually more traction and instills more driver confidence. Now there would be a compremise if you where running some super sticky tire and therefore would have to run a higher spring rate to compensate. But then again, you're already compremising by using the vehicle for dual purpose (daily driving and track use). If I was in your situation, I would pick up the KW's run the setup it comes with. See how it goes, if you end up over powering your springs due to a softer tire setup - get some higher spring rates. Atleast you'll have a far superior damper then the competition. |

V3 - independent rebound and compression adjustable, progressive rate spring utilizig factory top mount Clubsport - independent rebound and compression adjustable, adjustable camber plates for front, linear rate springs - additional cost is mostly made up from the top mounts, those German made top mounts are so costly due to the high quality (quality of bearings utlized) |

I would have to disagree with you that KW v1-v3s are in even in the same league as ASTs (twin tube vs monotube)..(not sure about Clubsport) when it comes to valving AST are on par with Ohlins, JRZ, Motons but no where near their price... the interesting thing is that when you have superior valving on a damper it necessitates a higher spring rate to properly match the damping charcteristics..another thing is I would be running Swift Springs w the thrust sheets which definitly improve ride quailty ..what I am trying to gauge is the how much ride quaility suffers between say a 700 spring in the rear vs an 800..I have had long conversations with guys running these heavier spring rates along with the proper damper and they swear the ride comfort is even better than stock..another to keep in mind is the actual rear wheel rate on the e92 is so poor that an 800 spring would translate to about 450-500 at the wheel. The general consensus is that since I am running the M3 subframe busing as well as an LSD an 800 spring would be optimum..I just wanted to pick your brain as regards to the ride quality on the KW Clubsports.. |

Also, The 335 really needs a shorter bump stop in the rear when lowered. I would suggest it even if you only lower a bit. I believe Dinan does this and maybe some other tuners. |

I was talking with you at HP I believe.

I've had my setup for >1 year, but did not realize until recently (a couple months ago), that many of my friends complained at how harsh the ride was in the rear passenger seats. Certainly better than expected, but still a LOT harsher than stock was their feedback. Whereas the front was as comfortable as stock, the passengers complained they felt every jolt in the rear. They would not want to ride long distance in the rear. I'm running KW V3 w/ Swift (336/672 - dampening 3 from firmest front / 9 from firmest rear). I was really surprised by the feedback. It's really interesting because we in the front feel the ride is as smooth as stock (LOVE IT!) So keep this in mind. By going to 800, the front ride quality will still be good, but the rear passenger ride quality will definitely be even harsher. Do you want to trade off by setting your rear dampeners even softer? Looking to hear more supporting statements from other Swift spring owners. Like I mentioned, we drivers don't get to sit in the rear that much, so this is probably why the feedback has been limited up until now. Please have your front passenger move back to the rear passenger seat, or have someone drive your car and perform the experiment yourself. Or maybe the other way would be cooler. Have them start in the back, and then move to the front to 'wow' them with your Swift setup
