i well im 16 and today i just bought my second car...which happens to be a beautiful 1992 318is its perfect...the seats have been covered with seatcovers since it was bought and the car was garage kept. the person who had it before me put on a momo carbon fiber shift knob. ive notied when i shift it just hold on to the shifter, the knob turns. how can i stop this...does it tighten or hook on tighter somehow? how can i do it?
