Hi,
If you want to keep it OEM then why not try a splitter for it? you can get a standard sport spliter or maybe go for abit more aggresion with the kamirai (not sure thats spelt right ) style one? you can also get TRD side skirts, like on an altezza, and even a TRD rear spliter to :winky:
all still keep the standard look but with a bit more detail.
