PSPEC tuning shift knobs are made from 6061 T6 billet aircraft grade aluminum. After machining, the shift knobs are sand blasted and powder-coated with a "soft touch" powder coat called Velvacoat. This unique coating has a fine textured finish which feels smooth in your hand. After powder coating the gear pattern is engraved with a high power laser beam that etches through the powdercoat and deep into the metal.

Use the link below to see the laser engraving in action.
Laser Engraving Gear Pattern

This knob is designed to be comfortable when held from either a top grip or side grip. A small stainless steel set screw is discretely located at the back of the knob which allows you to center the gear pattern before locking the knob in place with the supplied Allen key.

These knobs are identical in shape to the old PSPEC knobs which are very similar to Integra Type R. The PSPEC knobs have a more comfortable broader/wider top and mid section than OEM Type R. The gear numbers are NOT a font like you find on low-quality shift knobs. The gear tree and numbers are a computer image that is an exact match of OEM DC2 numbers and gear tree. 
 
These knobs will fit all Honda manual transmission cars. The thread diameter and pitch is M10 x 1.5mm

Allen key included with every knob.

This is a very limited run of only 60 shift knobs ever made like this.
