270g vs the 154g of the stock knob.
These shift knobs feature a precision CNC machined brass core for added weight as well as a delrin shell for durability, excellent appearance and ‘temperature management’. A heavier shift knob puts the weight towards the end of the shift lever. This increased momentum while shifting gives you a greater mechanical advantage, allowing for a much more positive feeling throw when rowing through the gears.
The delrin shell with laser-etched Boomba logo prevents the surface of the shift knob from getting too hot in the summer and too cold in the winter. These shift knobs make a great addition to your ST interior!
**Compatible with OEM & Boomba Racing Short Shift lever, or any shift lever with a thread pitch of M12x1.25 30mm**
