the upper and lower A arms were fabricated by the team. the frame section that the A arms attach too is stock, but missing the crumple section forward of the tunnel that the steering rack normally sits in. They added a plate to the front of it for strength since they mounted thier steering rack (stock does not have enough lock to lock ratio) to the front of it.
the upper part of the coilover suspension ties in with the tubular frame and rollcage they added.
