The ESCO-T6 is the rebirth of ACUiTY's popular ESCO shape in 6061-T6 aluminum. The ESCO design is quickly becoming the preferred drivers' knob due to its carefully-crafted profile. With a 40mm barrel-shaped upper portion, gently domed top, and tapered bottom, the ESCO-T6 fits beautifully in most drivers' hands. While spherical knobs have become popular, the truth is they allow a lot of grip variation when changing gears. By forcing a more consistent hand position through its unique shape, the ESCO-T6 helps to train muscle memory, making shifts more consistent.
