Maserati GranSport interior transformation!
We've replaced all the aging tec cloth with black Alcantara (tone matched to the carpet) stitching exactly as the factory would do.

Massive difference and actually looks more original than the white tec cloth.

Type-S setup by A.S. Motorsport for NSX.
Our S style wheels cnc machined from forgings in 17/18 using OE hardware.
ASM coilovers installed Type-S spec with OE S spring rates and 30 way adjustment.

On this NSX we setup the height like a S as well so a modest drop, damping equally comfortable. (Normal Type-S not S-Zero)

We added NSX-R chassis braces to further tighten handling.

Product update, our V2 NSX oil pan baffles introduced this year.

We've upgraded the design from punched round holes for oil collection to louvered baffles to better guide oil back in the sump and give a tiny bit more slush control

First batch nearly sold out but second one will come soon.
