Stance looks sick.

Is the performance upgrade as crazy as everyone says?

Thanks to Baan Velgen and MRF Engineering!

Review:

Malek did an amazing job installing and aligning the KW CS. The front is about a one skinny finger gap and the rear is tire is tucked about a centimeter.

Comfort:
These feel like the Eibachs, maybe a tad bit stiffer. I'm not sure what setting Malek put the bound and rebound to, but I just told him to work his magic and It will be primarily a street car.

I was hesitant to buy this suspension because of some of the threads I have read about it being stiff and for track only. People have told me to go JRZ, TCK or MCS if i want a streetable comfort level.

I have to say, these are awesome. They absorb fast bumps just as well as stock and over slow/large bumps its feels like its on rails. It follows the bump smoothly. Whereas the stock and eibach set up would be floaty.

From what I hear about the JRZ's, these feel the same. Or atleast I would have the same description.

Weight:
I thought the KW CS would be heavier since they are inox stainless steel. They box they came in said they weighed ~ 45lbs from USPS.

Malek packed my Eibach and OEM struts in to a KW CS box for me to use if I ever need a back up. After lifting these out of the trunk, I noticed that they were much heavier than the KW CS setup. They feel about 10lbs heavier than the KW CS. I think the major weight savings is in the coils. From what I have heard, Eibachs are Hi Ten steel (very heavy) and KW CS are light Alloy.

Handling:

I have only put ~ 100 miles on them so far but it feels super flat now. Braking feels better - less rear to front weight transfer. These feel really stiff when you need them yet supple when you are cruising. In fact, when I drive into my driveway, it feels so stiff that one wheel seems to lift off the ground when i enter the ramp sideways.

Yes im a poser. I admit it. I have never been to the track. However, I am changing my ways and I will be attending my first track event this month at california speedway. Some of my buddies are track junkies and are trying to get me hooked.

How much did the front and rear actually drop? I'm assuming you are on max height on the rears. Stance looks wicked!

I think the front is a one inch drop and the rears are 1/2inch from max height.

Thanks for the complement!

Another thing to note is that I clear ramps and bumps easier. Since the springs are stiff my chin doesnt dip at all like the oem suspension.

Once you get hooked on, you will wonder why you waited so long.

Looks good, but if you're mainly after looks, then how did you decide on the clubsports?

Steven,

I am glad you are enjoying and gradually warming up the KW Clubsports. They are amazing suspension pieces and defintely worth every penny. It absolutely transforms the car. As you get more seat time with the car, this will become more evident.

I have been tinkering with the settings a bit. At first it was 8/9rebound and 5/4bump

It rodes really well and turn in was sharp. However, It got a little to stiff at times driving down the 405 fwy near LAX. That fwy strip is really bumpy.

So, I backed it off to 6/9 Rebound and 6/6 bump and it feels just like my eibachs. Slightly stiffer than OEM but 10x the control. No more floatiness on bumps.
