    No. There are 3 tools: the spanner wrench; a 2mm allen wrench for the rebound damping adjustment and to lock the set screw on the spring perches; and a smaller tool to adjust the compression damping. I used a 1.5mm allen wrench for that adjustment in my pics because I had left the actual tool at home sitting in the box.

    Unfortunately, I think the answer is YES, you need to lift the car. The rebound damping is adjusted from the top, so no issues there. The compression damping adjustment at the bottom of the strut, though, is hard to use. As I've described in my earlier posts, it's a pretty clever arrangement, but with the struts on the car you can't really see into those slots, which makes it damn near impossible to get the adjuster tool into the little holes so you can adjust the damping. I think the best bet would be to remove the wheel so you can actually get your head in there and see what you're doing, and of course to do that you've gotta jack up each corner of the car.

    Now, is that all that hard? No. I could probably do all 4 corners in about 20min. But it would certainly be easier if I could just lie on my back and reach in around the wheel/tire to make the adjustment (as I was able to do with the DMS coil-overs I used to have on my Subaru, and as bigjim described with the QA-1s).

    That's what I did as well.

    Q: Will a small hole on the top of the plastic trunk housing work to access the adjustment?
    It's just a little allen wrench. You could conceivably use a longer tool to reach down in there, but good luck blindly stabbing the 2mm hole as you try to reach down behind the seat. Actually, I'm not even sure you could do that even if you tried - the strut tops are pretty far forward, and I think the rear seatback may lean back far enough that it's over the top of the strut tops.

    I'm not sure how firm it will go - I don't have any desire to just run the damping as hard as possible on track. Just like anywhere else, the suspension needs some compliance on track to maximize grip. If you read Koni's guidance on how to set up double adjustable dampers they actually advise you to start with everything on full soft and dial it up until performance degrades.

    I've done 3 track days on the KWs so far. The first two, at Portland Intl Raceway and Oregon Raceway Park, were with the "stock" setup. Between ORP and the third day (at Pacific Raceways) I swapped out the "stock" rear springs and installed 100N/mm springs (same rate as the front). In non-metric terms, I went from 570f/514r to 570f/570r. Honestly, I didn't notice a huge difference between the two setups. It would've been interesting to do back-to-back days at ORP with the two different setups, as ORP is a very technical track with lots of transitions that would've better revealed what (if any) differences there were.

    The handling on track (as on the street) was superb. It's tough for me to quantify how much better than the stock FG2 setup the KWs are, as I had a more aggressive alignment this time and my previous track days were on Falken FK452s vice the much more capable Bridgestone RE-01Rs I was running for these 3 days. Not to mention it's been 6 months since the last time the car was on track. As expected, the car moves around less in transitions - less brake dive, less body roll - but it's still a 4000# car that's going to move around quite a bit. Pacific Raceways has some very rough pavement, and some pretty bump mid-corner sections, and the car handled that with aplomb. Turn 9, the really bumpy high speed corner, felt about the same on the KWs as it did on the FG2s. You might read that and think that's not a particularly overwhelming endorsement, but I think it's a good thing - the excellent damping characteristics of the KWs mean that they're able to keep the body motions well damped through that corner even though spring rates are nearly 50% higher than stock.

    Dammit! You said aplomb. I wonder how many people have said aplomb here?


    Anywho, how did you like Oregon Raceway Park? A SHO owner posted a video of clockwise and counterclockwise run in his SHO at ORP and it looked like asphalt just laid in some hilly pastures. But it looked fast with fairly high-speed corners...

    Before you said it, aplomb had only been used a total of 12 times, the first time in the CTS-V forum, impressively enough...

    Re: Got the K dubs installed today

    Wow, and I thought only baseball statisticians came up with crazy shit like that!

    ORP was awesome. It's actually not a very fast track - I might have topped 100mph heading downhill into turn 3 (running CW), and I was at about 100mph heading into turn 1. It was all 3rd and 4th gear. I need to get some of my videos captured and posted, but having watched some already I can say that it really doesn't give a true flavor for just what a rollercoaster ride that track is. Very technical - lots of off camber or blind or cresting corners. Good stuff.

    Re: Got the K dubs installed today

    No issues to speak of. I softened the bump damping a couple weeks ago, as the cold weather is coming and I don't need the car in full attack mode for the winter. Traded vehicles with one of my buddies so I could use his F350 for some towing and he commented when he gave the car back that it rides nice. I continue to be impressed by the nice compromise that KW pulled off - firm but fluid ride, it's pretty much exactly what I was looking for.

    Re: Got the K dubs installed today

    No issues, I do get an intermittent noise, I think the same one the GC guys talk about, but don't have the time to diagnose it. It really doesn't bother me that much. I got a mailer this week from the place I got mine at for 15% retail of the kits. I don't know if that's a good price, but the place was reliable and got them to me in less then a week. If I had to do it again I would, immediately and before the last V day. Although I'm glad I didn't have to experience my first track day with them, I can not wait to track the car now. The cold weather sucks, as the car is way more then cold street / tires can handle and it's tuff toning it down...

    I gotta get a ride in your V and test these babies out, Mike. My friend might get these on his M3 as well. I want to do headers first, however.

    Q: about setup at insatllation time?
    How easy/diffcult was it to setup the KW suspension?
    .....so it can be great at the track..

    Re: Got the K dubs installed today

    I did the install by myself in a day at the Navy Hobby Shop - I would say it was 6hr or less, but I don't recall exactly. It couldn't have been any more than 8hr, since the shop isn't even open that long. I had the car on a lift, and had access to the air tools and spring compressor at the Hobby Shop. A more competent mechanic with another set of hands could I'm sure take a significant amount of time off what it took me, and it probably wouldn't take me near as long the second time around.

    Out of the box the damping adjustments were set to KW's recommended settings, and those were more than capable on track. Could it better with more tweaking? Possibly, it's just a matter of taking the time to develop a plan and then having the track time available to do the tweaking. Much like I've found doing track days in my Subaru, my grand plans to adjust the damping settings and "dial in" the setup gets thrown right out the window once I'm on track. If the car works, I'd rather be out there driving than on my back in the paddock fiddling with damping adjusters!

    Re: Got the K dubs installed today

    So if im getting this right the kw are great for adjusting your height and driving comfortably on the road and then able to stiffen up for the track.Now if your looking for staight track/aotocross setup fg2,new springs and new sways we be the ticket?

    Re: Got the K dubs installed today

    bdawg- AAIIIC can answer better, but I think it could be a PItA to adjust once they are on and all buttoned up. Now that I think about it, the bottom adjust ments aren't too bad, it's the top that's a killer. The strut tower bar and rear seat has to be removed to get to the adjustment points.

    jerry- I'll tell you the faster I go the more stable the car feels if that makes sense.

    Darkman- or for anyone, does the cold weather adjust ride height? Does the fluid compress and make the car lower? I know they sag a little over time and settles on a final ride height, but with winter tires sometimes they rub (really really cold) and others it doesn't.

    Generally, cold weather should have no effect on ride height. The only possible exception that I can think of might be with the rear Nivomats on the V to the extent temperature affected the self-leveling behavior.
