Jdm wr1

I have a wrx sti jdm that comes up as a wr1 on insurance I've heard it's a stronger engine it's a wide track with dcdcc as well I want to tune the engine to a higher spec any suggestions

I have an imported car and the dials are in kph any one know how I can convert it to mph

I'm looking for the plastic grille housing for the front as mine is looking very dull, I've managed to buy the mesh but can't find the housing anywhere. Dose anyone know where I can find a gloss black one?
