This is exclusively from HP Autowerks, Inc. No other rear coilover spring setup offers you this function. Period! I am sure others will copy this soon...Some have tried and failed(you know who you are!).
Harold,

Is the rubber perch located in the lower control arm resused with main and or helper spring? See item 8 in photo?
