want to ask a chap on here, m4rk i think he's called... i think! he does a part that compliments the kits really well, replaces the bright orange ball with a much tighter peice and makes the shif 100% better!
i did this, takes all of half an hour if that, makes a massive difference and its cheap and noticeable! cant go wrong!
im reletivly sure that the 16v uses the same bush kit, but ask at the factors and they will let you know.
