For someone like me looking for <1k wheel, I have a tendency to lean toward the GPI kit. Keeps compression and is an upgrade from the factory rod/piston. I would think the CMS cost would align more with 1k+ builds where the better parts would make more sense.
Has anyone done the GPI kit here? Also what gaps are you guys using?
