As mentioned the R32 Zorst will not fit on the ED30 rear section and the lower (inner) valance cannot be removed, tis all one piece unlike the R32 one which has a separate lower valance/splitter. All the R32 rear ends have reflectors, you can have them filled, painted etc but IMO they look good on a Candy. The rear in that photo is aftermarket I imagine. Keep an eye out on the forums as they pop up every now and again.
You need to get an OEM lower section from an R32 painting in Candy, an aftermarket R32 Cat Back or TBE system, pretty sure all the usual companies do an R32 option for the GTI/Edition30.
