I have never tried the KW, but a friend has them on this M Roadster and is pretty happy with them.

I just installed TC Kline setup. VERY nice compromise for street and track use. Handles better than stock, and actually rides better than stock. Reset the shocks and it does nicely on autocross or track.

Koni double adjustables, with threaded front bodies, 400 pound/inch springs all around, rear adjusters, rubber rear shock mounts, and camber plates. About $2600.

Ground Control's DA setup is about $500 less than the TC Kline kit. If you considered it, what were the attributes of the TCK kit that led you to your purchase?

I like the KW V2's. I had PSS9s before I switched (PSS9s were too soft for track duty). The KW's do ride stiffer then the PSS9s so you'll have to adjust them to your liking. KW's have more stiff, stiffer, hard, and rock solid settings then soft settings. The KWs are adjusted by an allen key so you'll have to rotate to one side all the way then count how many turns and do the same to the other side. The good thing is you don't have to get under the car to make the adjustment. The bad is you'll have to make a cut in the trunk liner in order to get to the adjustment.

So far, I like the KW's better the PSS9s. As others have stated, the GC and Tien's have been getting great reviews. You may want to investigate a bit more.

If you are just using it for street I would have to recommend the TC Kline setup. As pinecone says it handles better than stock and is much smoother over the rough stuff. TC gave us his Comp Pkg M3 w/the setup that pinecone stated at O'Fest and told us to have fun. It was very strange driving around looking for speedbumps, potholes, road irregularities, etc. It handled them all extremely well with improved handling over stock(shocks set at lightest setting). TC definately made out good as 3 people bought kits from that one drive.

Coil overs are overkill for street use. Just get some Koni S/A shocks and springs.

a) GC doesn't include rear shock mounts ($90 for GC, $129 for TC Kline ones).

b) GC kit uses SINGLE adjustable rear shocks. "Pre adjusted to spring rate". TC Kline uses Double Adjustable rear shock, top adjustable for rebound, bottom side adjsutable for compression.

c) TC Kline shocks are costom valved and made by Koni for their use.

d) TC Kline uses custom designed springs that allows you to swap springs without changing ride height and corner weights. So you can go to the track, swap in higher rate rear springs, reset the shocks, pop on your R-comps and have a more track tuned suspension. Reverse for dirivng home. Basically the free lengths change for the different rates. But rear spring swap is obtional, the car does very well with 400 pound springs all around.

e) TC Kline answers their phone every time I have called. And the people you talk to all know their stuff, where at GC you really need to talk to Jay. Which can be hard at times. But Jay really knows his stuff.

f) TC Kline gave us a bit of a deal on buying more than one suspension at a time. True, I did not ask GC, but TC was standing there when a friend drove the car, and offered free shipping.

But the GC setup is very nice, and I like their stuff. And I would have been happy to get their stuff, and have recommended to others. And advantage, GC has a wider range of srping rates to play with.

It was just that I got to DRIVE TC Kline's car and liked the ride and handling. I watched TC run the O'fest autocross and the car was sweet through the transitions and very fast overall. I saw the car on the track and it performed well, and I got to drive the car, and with the same setup used for track and autoX (except for shock settings) the car rode better than my M3 with stock springs and S/A Konis (pre-adjusted by GC for use with stock springs). And it still handled better than stock. I did not have a chance to drive a properly setup GC car. They need to be at O'fest next time with demo cars.

Bottom line, you will not go wrong with EITHER setup.

If I were going to do a pure track car, or race car, I would probably have gone with GC, but with Advanced Design shocks, unless teh budget would allow Motons or Phlins.

I disagree. I have that setup, and the TC Kline with 400 pound springs rides better than stock, even lower and on 19s. And handles better.

You need to drive one of the cars this weekend with this setup. It is SWEET. You are running stiffer springs.

Downside of the TC Kline setup is you cannot slam the car, if that is what you want.

And FWIW, Terry, you can only swap springs without altering corner weights much if you're around 700-750lbs. per corner.

There have been A LOT of complaints about the adjusters breaking. There really is no good reason to not go with TCK or GC.

Also they are VERY stiff, much more track than street oriented. PSS(s are the other way, the springs are way soft, much too soft for good track performance.

Having been in both proper prepared GC and TCKR M3, I have come to this conclusion;

GC is spring bias-let the spring do the work
TCKR is shock bias-let the shock do the work

I was leaning toward GC at first but after a great deal of seat time in TCKR, I am leaning the otherway.

It would be nice to put shock-dyno of Konis from both camp compare to off the shelf Konis. I wonder if all three will be the same or all different.

Again, the nice thing about the TCK setup, is you can switch from street to track by chaing shock settings. Perfect? No, but it works well for a dual purpose car.

And be swapping in 500 pound springs in the back, it works even better.

Cool, they are not listed as coming with the kit.

Nothing at all worng with the GC setup. Or the TCK, they are both very nice setups.

I'm not sure that your statement is going to hold true for everyone, it really is up to personal preferences. I replaced my shot OEM's with the Koni's this spring, not wishing to spend the $'s on coilovers.

After 6 months, even on the hardest setting, they are squishier than I would like them. I've only done 1 driving event, so this I'm pretty much 99.9% street use. I wish I handn't wasted my money on the Koni's, as I'm going to have to by coilovers at some point.

No, they just have incredibly crappy damper and spring settings. It's not track oriented. The H&Rs just suck.

Of course there are always exceptions.

The original poster sounded as if he was content with the OE ride and simply wanted to lower the car. In that case Konis and springs are a fine option.
