I don't know about you, but STI is the first thing that pops into my head when I think of Subaru. With decades of racing pedigree behind the name and 30+ years of tuning and development worldwide, the STI name is synonymous with performance.

Since GrimmSpeed was founded, the STI line of cars has been our specialty and we have engineered over 100 products specifically for the EJ25 engines that come in these models. With Subaru ditching the STI models in the USA for the 2022+ models years, the legacy will live on, and GrimmSpeed parts will play a huge role in that!
