Subaru STI chassis codes are the quickest way to confirm fitment. Common identifiers include GDB (2002-2007), GRF and GVF (2008-2014 hatch and sedan) and VAB (2015-2021). Some parts are shared with WRX chassis such as GDA, GGA, GE8, GH8, GV8, GR8, VAG, VBH and VNH, or with BRZ and Toyota 86 models where the platform matches.

Check the individual product title and description for the chassis codes, model years and any body-style notes (sedan or hatchback). Where a part is transmission specific, such as manual-only shifter components, that is noted on the listing.

Most Perrin items are bolt-on designs that use factory mounting points, though some require removal of intake piping, undertrays, exhaust components or suspension hardware. Basic metric spanners and sockets, torque wrench, jack and axle stands are typically needed, and some kits call for a thread locker or new gaskets.

Installation by a professional workshop is recommended, particularly for suspension, drivetrain, exhaust and oil cooler components. Always follow the manufacturer's instructions and torque specifications supplied with the product.

Do these parts suit Australian-delivered STI models? Fitment is determined by chassis code and model year - compare the codes on the listing with your vehicle's build details.

Will a Perrin intake or boost solenoid require tuning? Some induction and boost control products are intended to be used with a suitable tune. Check the product description for guidance.

Are WRX-listed parts compatible with an STI? Only where the STI chassis code is also listed. Many Perrin parts cover both models, but others are model specific.
