Subaru Impreza 2.5RS Rally Car Specs

UPDATE: I added Amazon links so the products are much easier to find online.

Here is my current list of modifications to my rally car.

Obviously, I will share any new modifications along the way on this blog.

Just to get this out of the way, I am running the Open Light class, which is a non-turbo all-wheel-drive class. This is why I will be sticking with the EJ251 that came with the car. One day when I decide to go to the Open class, I will switch over to a turbo engine.
