I agree with this as per what my books says, but only on the ZOK suspension.Factoryoemparts? Thats where i got mine from and they are indeed the zok option for the le5 and not the lnf. The title is missleading since it does say "Sky Solstice Springs Shocks GM Bilstein New Set Z0K FE3", but its cleared up through the rest of the ad. Im not trying to argue with you but thats what I get from your picture and the price you paid.
But the second perch is there on both setups. It was an option to be removed at the dealership prior to sale if the customer wanted. Was only there for clearance during assembly and shipping purposes as it put the car close to that of the stock height.
