KW HAS Kit Troubles

I wanted to improve the stance and drivability of my 17’ 911 C2. Like anyone, I researched the options and believed that the KW HAS kit provided the best options. I knew I would the C2 wasn’t going to be tracked so coilovers were a bit overkill but the car would benefit from a better overall stance and suspension. Thinking that springs alone wouldn’t provide the adjustability needed, I chose the next best thing. I chose a shop near where I live that was an authorized dealer/installer. After 3 days, I got the C2 back and the stance wasn’t where I thought it should be and asked the owner some questions. Why isn’t the front lower? I was told that the front suspension was bottomed out and no further adjustment could be made. The KW webpage promises anywhere from 0.6” to 1.4” adjustment . These kits aren’t cheap so expectations are high. On my C2, I only got 0.37” ! Thus begins the search for answers. Contacting KW was the next step. I did so via the website and within a few days, I got a response. Not a very encouraging or helpful one but nonetheless a response. After jumping through some hoops for KW, like measuring distances from hub to fender, from knuckle bolt to spring perch and so on. I was told that the engineers in Germany said that ‘everything’ was within spec. One particular measurement they used was the knuckle bolt to spring perch. Mine measured 130mm, however, the install manual listed 135mm as the minimum. I never got an answer as to why or how that was within tolerance. I repeatedly asked why the product description listed 0.6” to 1.4” adjustment when that never happened on my C2. Again, no answer from KW. So now I have a very expensive suspension system that doesn’t work as advertised. Anyone considering KW may want to take a second look elsewhere.
