I've got the S14 5sp in my S15 and have just swapped it out for the apex short shifter. I'd say it rattles a lot, and if its was my daily driver it'll do my head in. Apperantly all short shifters can rattle, I can take it apart and change a few things, which I may do. So just saying as I found this out after fitting it. (can always go back to std)..
