these seats and rails were originally out of a fresh import gtr32 - the owner was quite big and didn't fit. For my s15 (and all silvias/180s), one mounting point was approx. 3cm too short so that bracket was cut off and a new plate welded on by a professional. To have this fit skylines again all you need to do is drill a hole approx. 3cm in, no welding required.
the seats have no branding - choosen because i didn't want to have a big bride/sparco/recaro logo that say "steal me!"
the harnesses can fit with no modifications; if you want to run with the optional 5th and 6th point (that go around your crotch area) then you will need to find a mounting point below the seat.
