Pics of all the knobs as promised.
Here are the pics.
1st one is the perforated knob.
2nd and 3rd pic shows the performance knob and the perforated knob together.
4th, 5th and 6th show the performance knob and stock knob next to each other.
The stock knob is horrible. The aftermarket knobs are shorter, and are more comfortable in your hand. Plus they look better. Well worth the price. I also did the perforated brake handle upgrade at the same time and love the look.
Hope this helps!
