Why not just take it to a reputable custom body shop and have them fabricate one?

 

u could goto the shop, but me personally i'd wait till cobb finishes with theirs and maybe see if anyone else is going to finish one soon. let those who hav started finish so that any big problems that happen b avoided with yur car. a custom fabrication is pretty much permanent and u don't want them guessing on yur car.

 

Check with COBB. They had a wide body kit on their WRX in the SCC AWD shootout. Check it out @ you local magazine store
