Tuning parts for the 3.3

Does anyone know pages with tuning parts (spoiler, diffuser, etc.)? I’m still looking for the certain “something for the sting. The emblems were just the beginning. Tomorrow there is still disc foil on it and in 1-2 months the sports suspension. About Google and Co I haven’t found anything really “usable” yet… The only parts I had found were the WestCoastCustoms and eBay parts.
