We designed these on the JGTC Style shift knobs we would see in the JDM Grand Prix, and Euro Rally Race cars.

Machined from Solid Nylon, they are super tough and lightweight. 

They are non-porous and will not stain or change color over time. 

They will ony get smoother and better to touch over time.

These are threaded with a 10 x 1.25 internal thread.

Available in black or white Nylon.

NOTE*

For FC RX7 1986-1988 Shifters have a 12x1.5 thread pitch

only the 1989-1991 FC Shifters use the 10x1.25 thread pitch
