570/800 is very similar to the CS; I think anyone looking for a more track oriented set up should be wary. Not to take away from this review and the positive things about them but it IS a clubsport setup afterall and looks to be more towards a balanced approach of street AND track since the rear springs are NOT linear; they're progressive.
Thanks again for the review; like many others looking at clubsport varients we bypass Bilstein since it doesn't seem readily available, but it is , and the PSS10 and 16s aren't dual-duty enough. |
Actually it is geared more towards track work, trust me. You could easily clubrace these on slicks, with much higher rates. The damping and valving is aggressive, but the wide adjustment range allow for very good manners. MCS and other comparables are no more hardcore than these, all with similar internals, and rebuildable.
People tend to either forget, or simply ignore that KW's are twin tubes, which is why they feel like they do. BMW uses them in cars like the GTS because they are cheaper and offer better street manners. Plain and simple. IDK what anybody says, a KWCS is simply not in the same league as a Bilstein CS. Ask any competent shock tuner, and you'll hear the same thing as a majority.
The rear spring actually is linear, it just has a "progressive" section on one end that fully compresses when the car is on the ground. It's simply a built in "helper" spring. The spring also has a small angled section to help with articulation as the control arm moves through it's range of motion. This is really nice, as it helps prevent coil binding, since there aren't any articulating spring perches, which I used to use on my E6 M3 track car. This is a very well thought out piece of engineering you don't get with most other company's "kits". Also, it doesn't make any noise.
This is the same linear-and-helper spring type as used OE on the 997.1 GT3/RS, which I previously owned. It works very well actually, for when on streets or bumpy tracks. If you want another spring or rate, just install it. That's easy. What's important is that the dampers are valved to handle these and considerable higher rates. I've validated that with the Bilstein motorsport directly. I have found that with an adjustable rear sway, I don't need to increase the rear rate for my current use and setup. This also helps to keep road manners in check.
Not trying to persuade anybody, just passing on what I know or learned.
