Grid Life #1 trophy at Mid-Ohio
The Record

Two Championships.
One Car. One Driver.

In 2023 and again in 2025, Dewey DeWitt took the GRIDLIFE Street Mod championship in the same 1995 Subaru Impreza GC that everyone told him was the wrong car. The same chassis. The same number. The same philosophy: build it right, not build it popular.

The Engine

IAG 2.35L.
Power Is Classified.

IAG Performance built the engine from the ground up: a destroked 2.35L closed-deck EJ257 with GSC S3 billet cams revving to 9,450 RPM. The power map is classified for competition reasons. The timing sheets say enough.

The Chassis

1995. Still the
Fastest Thing Here.

A 30-year-old GC chassis with Racecomp Engineering T2-RS coilovers by KW RACE, true 2-way compression and rebound adjustment, EBC brakes, and an IAG STI rack swap. Not restored. Not modernized. Purpose-built for one thing: the timing sheet.
