Another set of KW springs going into the dumpster!

We are converting yet another set of KW V3 with Swift springs, this time with the request of the owner to install helpers springs. No camber plates were requested as the car is strictly a daily driver for the time being. The additional negative camber needed to reduce understeer will come from the slight lowering of the car and M3 wishbones and proper selection of spring rates. We settled on 400F and 800R for this particular project.

With the installation of Swift springs and thrust sheets some of the noise that has plagued the KW V1, 2, 3 or even the CS may be a thing of the past.

As you can see the use of Swift springs make the front coilover over setup more compact and lighter by about 2 lbs.

Spring rates are disclosed in the op as 400F and 800R.

Way better than the KW V3 out of the box that is for sure. Less noise and better handling are just few other benefits with the Swift spring conversion.

I never realized how wide the KW springs were up top when compared to the Swift. So the swift springs and KW springs both fit the stock upper mounts the same?

Yes, pretty much. We have a custom upper spring perch/hat that makes everything work perfectly and with much improved performance.

Do your kits with the swift springs come with this perch or would it need to be purchased separately?
