I thought these only lowered the car 20mm?

They are basically KW V3, so the front can go as low as, while the back is limited by the length of the spring (the KWs use a much shorter spring with a helper spring).

That said, there are a couple of options to get the rear lower without spending money:
1. don't use the adjustable spring perch and retain the original upper spring seat
2. the spring is located on the adjustable perch by a two-piece seat, so ditch the rubber bit and retain the plastic spacer.
