2014 spring choice for Tokico HTS Shocks

[tophus]

I have trawled and trawled this subforum to no avail...
I have a 2014 (NC2.5/3) stock. I recently acquired a set of Tokico HTS springs off here which came with NC1 springs, so I need to now source some appropriate springs.
My question is what, as a Melbournian, seek out.
I can get some Progress Technology springs for about US$340 shipped, or possibly cheaper if I wait until a local retailer can get them.
I could get the FM springs, shipped from them at what I assume would be a much higher cost...
My biggest concern, after seeing that Progress have two different variants of the front springs, is that I could end up with a local alternative which is not suited to the NC2.5/3.. Is there a tried and tested solution for my car that I don't know about? or a good local supplier?
Thanks guys!
