Rough. Tuned
Right.
Engine builds, boost, fabrication and full track support — everything your Japanese weapon needs, under one roof.

RoughEdge Motors is a Japanese-performance workshop for people who want it done properly — not fast, not cheap, right. From a tidy bolt-on to a bare-shell, forged-engine monster, every build leaves with the numbers to back the noise.
Engine internals, forced induction, fabrication, suspension, aero and full trackside support live under one roof. One crew owns your car start to finish, so nothing gets lost between shops.
