shooter 4mm chassis
the chassis' finish looks great. i was also pleasantly surprised to find out that the chassis came with shooter's alum 14mm engine mount (color is very dark grey...cool).
am not sure if the other brands also include their engine mounts with their chassis.
downside is, the clutch bell rubs on the chassis just a tiny little bit and will need some dremel work to get it to fit nice and right.
also have to say that the sato seiki parts are also quite good in terms of finish and fit.
