This car started life as a 2022 Subaru WRX and our job was to create the STi variant – since Subaru pulled the plug on the STi for this new generation. By Jan 2023 we created the very first STi variant of this car and gained a large following on IG/FB: @RZ1USA

The Phase 2 build was extensive, with a full Cusco tuned chassis and a bunch of parts to make the car outperform its competitors in every way possible – including reliability. The aim was to create an ultimate road and track vehicle.

This has been a no expenses spared on this build with all details on the RZ1USA.com website.

This vehicle is used to attend specific meets, track days and weekend canyon carving events. It has not been used as a ‘daily’ – although possible if you’re okay with a harsh ride.

This vehicle gets a fresh motor oil change every 1000 miles with Motul 300V

Transmission & Differential is running RedLine Gear Oil

Engine Internals are stock, although there was a plan to replace the head studs with ARP pieces to allow us to tune the car to over 550 lb.ft.

This vehicle is AWD and we added the DCCD controller to allow us to split power from 50/50 to 20/80 to rear wheels (when needed) by the iWire In-Console Controller (Like the STi)

All tires replaced March 2024 with no track hours.
The interior is complete – No weight savings

Front seats have been replaced. Driver’s seat has a 6pt harness as well as stock seatbelt – DOT OE Equipment.

Exhaust is a track spec but we do have the Street/Race mufflers that can come with the car also. Both catalytic converters have been replaced with high-flow aftermarket pieces.
There are no nasty surprises with this car. It’s been well maintained.
