I've been doing around for options on lowering the 560sec and pretty much only came across the h&r springs. I was talking to a contact of mine whom I get bmw wheel information from and asked him if he had any connections to get some amg2 monoblocks. We chatted for a bit and we started talking about lowering the car. He then told me he had a set of vogtland lowering springs which would lower the sec 40mm. Do any of you guys have thoughts about the vogtland springs? pros? cons?
