Best OLM Upgrades for Subaru WRX and STI: Lighting, Exterior and Interior

OLM is one of the most recognized brands in the WRX and STI aftermarket for a reason. It is not because they make one iconic product. It is because they cover the car from front to rear and inside out. The depth of the OLM catalog for the WRX and STI platform is unmatched in terms of fit, finish, and design quality.

This guide covers the best OLM upgrades across every category for the Subaru WRX and Subaru STI: lighting, exterior, and interior. See the full picture before deciding where to start.

OLM Lighting Upgrades for WRX and STI

OLM builds some of the strongest lighting options available for the WRX and STI platform. Three products stand out as the core of the lighting lineup.

The Hikari Series is a full LED headlight assembly replacement for the 2015 to 2021 WRX and 2015 to 2017 STI on halogen trims. It is a plug-and-play upgrade. Output is significantly better than the factory halogen units and no wiring modifications are required. Our post on the OLM Hikari Series LED headlights covers compatibility and what the upgrade delivers in detail.

The Evolution tail lights replace the full tail light assembly on both sides of the 2015 to 2021 WRX and STI. Sequential turn signals, custom bar and lens combinations, and a significantly more aggressive rear end look are all part of the package. The NB+R fourth brake light fills the rear fog light housing below the main tail lights. It adds brake and reverse light function the stock car does not have. Many owners run both together for a complete rear lighting setup. The OLM Evolution tail lights and NB+R guide covers the difference between the two and how to choose.

OLM Exterior Upgrades for WRX and STI

The OLM exterior catalog covers every panel and surface on the car. Front lips, duckbill spoilers, side skirts, mirror covers, carbon fiber body panels, and under-hood details are all part of the lineup. The depth of options at different price points and finish levels makes it possible to build a cohesive exterior look without mixing brands.

The S208 Style Front Lip is available in matte black and carbon fiber. Both options work on any color WRX or STI. The RD2 Style Carbon Fiber Duckbill Spoiler transforms the rear silhouette of the 2015 to 2021 WRX and STI. The blade profile is clean and purposeful. Mirror covers come in paint matched, carbon fiber, and JDM-style options. Under-hood details like the carbon fiber fuse box cover finish the engine bay without requiring major modifications.

OLM Interior Upgrades for WRX and STI

The OLM interior catalog is the least talked-about part of the lineup and one of the most impressive. The WRX and STI interior is functional but plain from the factory. OLM makes a comprehensive range of carbon fiber trim pieces that transform the cabin without requiring any permanent modifications.

Shifter trim and console covers replace the factory silver plastic with carbon fiber. The quality matches the exterior upgrades. The ebrake handle comes in the Signature Series with colored accents or as a full carbon fiber replacement. Either option immediately elevates the feel of the interior. Steering wheel covers add a dry carbon fiber layer to the factory wheel on both manual and automatic versions of the WRX and STI.

AC vent trim covers, door sill covers, switch panel covers, and dash trim pieces complete the picture. Each piece fits exactly like the factory part and installs without cutting or permanent modification. The result is a cabin that looks as finished as the exterior.

Building a Complete OLM WRX or STI

The strongest OLM builds are the ones built with intention across all three categories. OLM designs their products to work together. The carbon fiber finish language is consistent from the exterior to the interior. Dry carbon, forged carbon, and matte black options carry through both categories. The build reads as a single cohesive vision rather than a collection of individual parts.

A car with OLM headlights at the front and Evolution tail lights at the rear is a strong start. Adding a carbon fiber front lip, duckbill spoiler, and mirror covers on the outside takes it further. Shifter trim, ebrake handle, and AC vent covers on the inside complete the build. Every surface has been considered. That level of detail is what separates a finished car from one that is still in progress.
