^ if you shap that extension, you have to lay off the steroids!!!
It'll hold plenty of force. Any thicker would simply be overkill (or added weight)
Here are a couple more of the ACETAL COPOLYMER
which is similar to "DELRIN" (Acetal Homopolymer) knobs I have completed within the last 2 days.
This material is awesome! It is lightweight, making most of the knobs weight around 75-110 grams. It is black in color. It remains about the same temperature as the steering wheel so you can shift easily and comfortably even when its negative 10*F outside! This material is extremely durable and wear resistant.
The lightweight actually improved the shifting feel on my car! I have the full assortment of TiC & kartboy shifter products on my 5speed and the light Copolymer knob simply flies between gates with amazing amounts of feedback to my hand. Its more "in touch" with the car than any of my aluminum knobs ever felt, even though they weigh more.
Im working on developing an inventory right now.
Here are the pics:
WRX Tapered Piston knob:
WRX "G4" Style knob:
and STi Sphere for the 6speed!:
Prices will be released on the site, expect them to be extremely competitive for the best knobs you can get!
