APR aero is chassis and year specific, so identify your car before ordering:

• GD/GG (2002–2007) — Impreza WRX and STI sedan and wagon. Splitters are split into 2002–2003, 2004–2005 and 2006–2007 fitments to suit the facelift front bars. GTC-300 61″ and GTC-500 71″ wings and the rear diffuser cover this chassis.
• GE/GH/GR/GV (2008–2014) — Impreza WRX and STI hatch and sedan. Splitters for 2008–2010 are listed separately for WRX and STI. Brake cooling plates, rotor backing plates, the alternator cover and Formula GT3 mirrors are listed for this generation.
• VA (2015–2021) — WRX and STI sedan. Note the 2015–2017 and 2018–2021 front bar splits: 2015–2017 splitters are offered in APR lip, OEM lip, WRX-only and STI-only variants, while 2018–2021 splitters come in APR lip, OEM lip and no-lip versions. Choose the variant that matches the front lip already on the car.
• VB (2022+) — current WRX, covered by the 2022+ carbon wind splitter with rods.

Some parts are STI-only because they rely on STI bodywork or Brembo brake hardware — check the year and model in each product title against your build before ordering.

Installation by a professional workshop is recommended. Wings mount to factory locations on the boot lid using billet aluminium pedestals, and splitters use stainless steel support rods that tie the splitter back to the chassis or bumper structure, so accurate measurement, drilling and torquing matter for both safety and finish.

Plan for basic hand tools, a drill with suitable bits, thread-locking compound and a second set of hands for larger panels. Test-fit every panel before final drilling, allow for panel gaps and ride height, and check state and event regulations for wing overhang and splitter protrusion. Parts are supplied in pre-preg carbon fibre with a UV-resistant clear coat; keep panels supported and protected during fitment to avoid edge damage.

Which APR wing suits my WRX or STI?
The GTC-300 is listed for the 2015–2021 VA STI and, in a 61″ span, for 2002–2007 cars, with a 71″ GTC-500 also available for the 2002–2007 chassis. Match the listing to your chassis and year.

Why are there several splitter versions for the same year?
Splitters are made to suit different front lips. The 2018–2021 range covers APR lip, OEM lip and no-lip cars, and the 2015–2017 range adds WRX-only and STI-only fitments, so the splitter matches your existing front bar.

Is APR brake cooling functional or cosmetic?
The carbon brake cooling kits, ducts, cooling plates and rotor backing plates are functional parts designed to direct air to the front brakes, and are listed for 2008–2014, 2015–2017 and 2018–2021 STI applications.
