Carizma seem to be selling a fair bit of performance gear..
also, for tuners.. try the typical VL Turbo Tuners.. they are getting fairly deep into the R3*s now..
JPC, EAS, PET..
I dont think id go near Nizpro or AVO.. just heard a few bad things about them..
Also.. BGT are the stockists for APexi.. so they supply / tune etc.. dunno how good they are ?
