I had the KW HAS and removed it from my CS. The spring rates donít feel correct for the CS.

In comparison to the stock CS suspension the over all feel of the car felt softer more plush.


My objective with the HAS kit is not what others here are using them form.

I didnít want to lower the car at all so it was setup for stock height.

My purpose was to have the ability to corner balance the car for track use.

So the shock stroke and positioned remained the same as factory. So the shocks are not in the wrong 0 position since itís not lower or higher than intended keeping the EDC settings true to their design.

I was not able to find proper info of the spring rate range for the front but the rears are 12k which is 670lb/in range.

My goal now is to use GC coil kit with a 550/800 spring rate using ERS springs from Eibach.
