A simple enough modification, and inexpensive at £35, I have swapped out the standard shift knob for a Tomei SS, and I bloody love it. 
 
	If it cost twice as much I'd still consider it good value, it's made changing gear a much nicer experience, looks tasteful, and has got rid of an annoying squeak the standard one had. 
 
	 
 
	10/10 - would recommend
