Welcome to Perth-WRX.
There are several specialist subaru workshops in Perth you can talk to about mods.
A lot of us use and highly recommend STechnic in Maddington.
What the boys there dont know about Subarus, isn't worth knowing.
Other options are Maximum Motorsport and All Star Garage in Malaga.
Next major event coming up is the annual Colin McRae Memorial Cruise on Sunday 23/09/12.
