TEGIWA 'TR' shift knob is precision CNC machined right here in the UK and is manufactured from billet white Duracon(Thermoplastic). The properties of Duracon mean it will not get too hot or too cold and it is very easy to keep clean. There are a range of fitments available - just select your shift pattern and thread. These are made for your car, no grub screws here!!! If you have a 'pull up' reverse this will not fit.
