Manual transmission only. RoadsterSport R3 Delrin gear knob fits all MX5 Models & FIAT 124  

Made from Delrin so it does not get hot in the sun like metal gear knobs.
The under-cut of the sphere allows good finger hold on the shifter when flicking between gears without the need for a death grip on the knob.

The smooth transitions in the shape create a pleasing tactile experience for the best connection with the car and effortless shifts. 

Steel helicoil thread insert inside the knob so that you don't wear out the threads over time.

Internal thread placement carefully chosen so that once installed the shift knob rests snugly against the top of the shift boot and does not leave an unsightly exposed shaft like many universal gear knobs. 

This knob is NOT weighted.  Subtle laser etched Goodwin Racing "G" logo at the base.

When you receive the gear knob it will have a natural matte finish from the machining process. Delrin naturally polishes over time as you handle it, so any minor roughness or dusty look to the finish will smooth out and brighten with use.
