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**

This shift knob is awesome! Super high quality product, fits perfectly with the factory reverse and took about 3 minutes to install total including removal from packaging. Highly, highly recommended product!
I installed this knob along with the short shifter and bushing. The knob is noticeably more heavy than the stock knob and just a smidge larger in palm size. The delrin shell really does keep it cooler ( I would say more even temp).
Installation was a snap and the separate gate pattern inset means everything lines up perfectly once installed. No adapters needed with the stock reverse lockout, just twist on and go.
The heavier knob seems to help take out a lot of the "bounce" in the shift engagement.
