07 STI BC Racing coilovers - $500 Used. I don't know how many miles are on them because they came with the car. Swapped with factory setup. Spanners included. 07 STI HKS hi-power exhaust -$200**SOLD** Used. I don't know the mileage. Also came with the car. Swapped out for factory exhaust. 07 STI OEM air intake resonator - $60 New, genuine Subaru OEM. Still in the sealed bag. Part number: 46040FE020 I am located in Lake Elmo, MN.
BC's website shows a different part number for the WRX (F-02 rather than F-03 as pictured above). My guess would be the 5x100 vs 5x114 difference there (bigger strut bottom size or something I think).
