Hey guys,

I'm looking to do a suspension upgrade for my 07 E90 335i. I currently have the ZSP and I'm sick and tired of the bouncy/springy feel. I got the H&R sway bars but they made things worse in fact; turn-in is great but its harder to control the car during oversteer; the rear looses traction too quickly.

Anyways, I'm looking for a more planted ride which I can take to the track 2-4 times a year.

Any of you guys have clubsports or the tckline setup? If so, please describe your experience with them? How do they feel on street and/or track? Too stiff, too soft, too this, too that...

I know a lot of you guys have KW V2s. I am open to hearing thoughts on them too; but PLEASE NO V1, V3 or any spring/shock discussion.

Thanks a lot!

BUMP

Looking at something similar for tracking 2 - 3 times a year + autox's + Tail of the Dragon annual drive.....

Hmmm... no one? *bump*

Go with what ever has the higher spring rates and the most adjustability. This will allow you to tailor your ride and give you the most options for tuning the shocks. The reason I say to go with the higher spring rates is mine are 450 front and 674 rear and the car is not harsh at all on the road, it soaks up mid-corner bumps and the suspension reacts so much quicker than the ZHP suspension it's unbelievable. At the track, everything is taken so much quicker. You'll see a difference immediately once you hit the corners and can carry 10mph more through the turn than the stock suspension. Cars with much more hp, but without the suspension couldn't keep up with me on the track (yes, tuned 335s - I'm running a 330).
That being said - maybe another option for you is what I'm running, JIC-Magic Cross.

Swift. Talk to Harold.

[zsapphire7]

yea you can get swift spring applications for the kw clubsports too..

I had a couple issues setting up my JIC's but once you dial them in its heaven on wheels. Right now im rather soft 6f 7r and its very comfy, for the track its 13f10r. Spring rates on mine are 9k front 12k rear. -2.5 degrees of camber up front, a lil bit of spring preload and the car really handles 100 times better then stock. Whatever you choose to get, just like other said, get somethign with decent springs. The KW springs suck unless you get the clubsport suspension. I wouldnt even consider Kw 1/2/3. At this point its clubsports/jic/tck, Id get TCK if i could afford them lol

Why not do the M3 arms/bushings? It'll tighten up the suspension.

I think Orb had some issues with the Vorslag camber plates; I believe you have to get plates with TCK.

I would say that the TC Kline setup is more customizable than the KWs, and the following for TC Kline seems to be really strong at the track.

[Speediance]

So from what I've gathered after talking to knowledgeable people and searching this forum:
TCK is pretty good -- downside little pricey, possible noises from rear at high-speed, but Harold knows the fix.
JIC is good, contingent of proper setup/settings, but still could have potential issues.
KW V1,2,3 suck -- my observation after riding all of them; for people who want the slammed look for cheap.
KW Clubsport -- dont know much yet, the only KW setup I'd consider getting...

After talking to Harold, it seems that I may endup with TCK. He says, I dont necessarily have to get the camber plates if I choose not too, with TCK. KW Clubsport, I have to.

And yes, if I go with TCK, I'll go with M3 sways/arms/bushings.

But if more people chime in that'd be great...

[Clap135]

If you consider tck a lil pricey that means its in your budget. Do it. lol

[Speediance]

Well TCK and KW CS are pretty much the same price... Also I wanted to know the difference, hence the question...

[stressdoc]

Piss man, the setups you are considering are killer. Unless you are moderate/serious about track any of the dampers you are looking at w/ Swift springs and M3 bits are going to be awesome. I would pick Harold's brain and see if you can't get some test rides. It will be very easy to end up spending a ton of $ if you are not careful.

The other issue is that once you are at the level you are looking at other mods become critical. Reducing unsprung weight is one of my favorites. Volk 18" wheels, Stoptech trophy brakes, M3 bits, etc. will have significant cumulative effects. Strut and chassis braces. LSD!!! Lightweight battery. It never stops...

+1000.

I got my TCK, Vorshlag, M3 front bits setup working so well that on heat cycled tires at Infineon with stock brakes and pads I went sub 2. I'm an OK driver but the car as so balanced an could generate so much grip the worn tires still worked reasonably well. The best I ever did with the stock suspension was 2:05.5#. That's a big difference. Also, that 2:05.00 was with the same tires but they were almost new. DO IT!!!!!!

Do the plates also. You can balance the car perfectly. For instance, if you keep the stock camber in the rear then you can dial in -2.5 up front or track use and bring it back to -1.5 for street so you don't wear ft. tires on the inside. TCK plates are supposed to be a bit quieter than vorshlag but my voshlags only make a tiny bit of noise over high frequency bumps. Don't mind it at all.

Definitely get the rear M3 bushings put in and I might leave the swaybar for later. Tune the boy roll with the coilovers. Get the M3 strut brace to alleviate noise from the Koni adjusters in front. They rub on the stock ones.

How is this coilover as far as comfort compared to Bilsten pss10 & kW comforts ... also what is the downside of NOT running the vorshlag plates ... is there one because I read you don't need to use 'em with the TCKs ... thanks.

Had tck. Serious quality issues. Go with kw clubsport m3 hybrid kit. Kw now makes a kit to allow m3 suspension on the 335. Harold can set you up with swift springs if you want. However kw clubsport springs are pretty good. Hybrid kit is 400#/800# spring rates. Cost is only slightly more than regular e92 clubsport kit.

Out of curiosity, which TCKlines did you have and what quality issues did you have with them? I have TCKline DA and never had a single problem with them after thousands of miles and multiple track days.

Is the hybrid kit officially available or still only through Harold?

I've the kw clubsport incl ARB's and am happy with them. The m3 subframe bushings made it even better. am driving -2.8 degrees of camber in front allowing 265ers
the camberplates create some noice, but ok for me. ride is firm but nice. I didn't like it with rft tires that much though, with non rft I love it.

Clubsport is getting more and more famous world-wide. Therefore, KW has decided to develop the KW Clubsport. This new product line is distinguished by motorsport applications for race track and road use with ideal performance. Nürburgring Nordschleife is the most popular race track for using the KW Clubsport suspension kits. High performance sports cars, modified saloons as well as classical sport compact cars are tuned in weight, engine and wheels for their use on several race tracks. These improvements are made for a better handling on track sport events, race taxi drives, visitor drives and equability tests particularly on the Nürburgring Nordschleife. Due to these modifications of the car some parameters are changing. Therefore, the road setups are no longer ideal for the performance of the car. For this use KW offer special clubsport kits which have been adapted to the changed requirements by changing spring and shock setup as well as the installation of racing top mounts. Feel free to shoot me over a PM if you guys have any questions about this setup!

Long story with TCk's. They were defective out of the box. TCK and Koni refused to honor warranty.

KW M3 hybrid kit is now a new part number. Can be ordered from any KW dealer. NOTE: lower links are needed (kit assumes full m3 conversion). Harold can explain everything if you want to go through one source.

[T7R_Sky]

I have KW Clubsports myself. Really amazing handling! And on full soft it only kind of kills you as a daily driver!
