Hi All - I'm selling my ZHP and removed the Ground Control Coilovers and reinstalled the OEM suspension. I bought this kit directly from GC in February of 2015, it was installed later in March and has about 6000 total miles on it since. It's Koni sport inserts, GC custom Eibach springs, GC front camber plates and rear lower adjustable camber arms and all associated hardware.
I loved how this kit drove, stiffer than stock but not unbearable for daily driving. Lots of room to go very low.
The whole kit is around $2100 new from GC. I'm looking to get $1400 shipped, shipping will be expensive as it's very heavy.
P.S. Sorry the pics are rotated, image host flipped them.
