You will want stagea strut tops, not GTR. Definately for the rear and probably for the front as well, because they have to fit into the chassis OK.
I think your best bet will be a set of standard ones, aftermarket (if you can find them) is likely to be expensive, and be "pillow ball" which is a large bearing at the top which will probably flog out quickly in road use and start knocking, sending you crazy
