FS: ST XA Single Rebound Adjustable Coilovers for AWD Cars - KW V2 Equivalent

Selling a one year old ST XA coilover set for AWD E9x cars. Note the ST/KW springs have been replaced with brand new H&R springs and the ST/KW rear ride height adjusters have been replaced with H&R rear ride height adjusters. What do you get in this sale?

Front left and right ST XA dampeners- Fit AWD cars only. - Used ~1 year and <5K miles
Rear left and right ST XA dampeners - Fit AWD and RWD cars. - Used ~1 year and <5k miles
Rear H&R ride height adjusters - New; prefer these over the ST/KW height adjusters as you can adjust the ride height from the bottom without removing the tires.
H&R springs - New; prefer these over the ST/KW springs as they are a slightly higher spring rate and linear in the rear vs. KW's progressive springs.
Front and rear dampeners are external rebound adjustable and include KW rebound adjusters.

If you know ST/KW dampeners, then you know the spring perches are 61mm inner diameter. The H&R springs are 60mm. So how will the H&R springs fit on these front dampeners? I had the front lower spring perches machined down from 61mm to 60mm to accept the more common 60mm coil springs. So technically you can run any 60mm coil spring you desire with this setup and are not limited by KWs springs. Since I am including H&R rear ride adjusters, they are already 60mm in the rear and work with the 60mm H&R rear springs, or any 60mm spring you desire. Note: the front H&R springs have a 60mm lower spring ID, but the upper spring is the oem size and use your oem upper strut mounts.

All you need for install is your oem upper front strut mounts (or camber plate of your choice) and this is a plug and play setup. This is a custom setup and offers a lot of flexibility over non-adjustable dampeners since they are single adjustable and use common 60mm id springs. You could even use 65mm springs with a 60mm to 65mm spring adapter.

With adjustable dampening, soft compression, and using common spring rates, these offer a great ride quality. Just don't go crazy high with the spring rates if you prefer to run different springs.
