I'm not sure f he's keeping up with this thread... what he's told me is this:

At the time he wrote that, he was doing a KW coilover install / testing on someone's R56. The springs that Texas Speedwerks sent along with the coilovers were out of spec / not the springs that were ordered. The rear springs were progressive and they were not supposed to be. Texas Speedwerks took the springs back, and Greg ordered some hyperco springs since the install was on a timeline.

Then, Greg checked the damping of the struts. It turned out that his initial tests were down with the shocks too far from vertical, which caused some very bad results. After re-testing with the struts in their operating range / orientation, everything was fine. But the initial tests made it look like the struts were under-filled with oil.

I believe these two things are what caused Greg to say that he wasn't happy with KW. But, a few days later he emailed me that both "issues" were in fact not really issues.

Jason has this right.
I should have retracted this statement, but still not sure how I feel. One thing I want to say is that TSW is a top notch company and this is nothing against them.
What I don't like is that the springs did in fact dyno out as quite progressive in the rears. Now, do understand that this was a set of custom ordered coilovers via TSW as we asked for higher rates in front and rear. When I do installs for customers I always test anything I can, but the fact is that the majority don't, as they depend on the manufacturer to be selling them what they ordered. If we had installed these without the test then we would have had some strange tuning problems.

Anyway, I do think that the KWs are a decent deal.

Whew. You had me worried.

That sucks, though. Glad it got fixed in time.

Not sure where else to put this.

Im looking at getting coils and have been contemplating KW, amongst other brands, however living in Aus raises some issues with parts, shipping and what not. I went to a local tyre place that I recalled stocked KW and asked if they had any. The guy there said they don't sell KW any more and stock another brand. I asked why and was told "The KWs are cheap japanese coils and the ones we sell are made in Aus and are better quality."

From what I gather after reading online, KWs aren't cheap japanese coils. Getting pretty good reviews all over the board. And I swear they originated in Germany.

Am I right?

I was then quoted $2700 fitted, or $2100 for parts for the coils they sell. Shipping is definitely looking good.

He sure did. The other brand was Pedders. They are relatively large in Aus, but I have my doubts as to whether they are superior to KW.

Although KW is german, the struts are made in China these days.
