Real quick, i'm putting an s5 m/t mated to my s4 motor, what clutch stuff do i buy, s4 or s5?

 

They should be the same.

 

nope, not through autozone, apparently. the clutch sets are very different in price, by about $100. Does anyone know what size the disc should be, or if the throw out bearings are different, or how many splines they have? I love info.

 

well autozone fing sucks, they can't even get turbo rear brake calipers, why are you buying a clutch set through them anyway?

Go to clutchmasters.com and get their s4 kit, then go to mazdatrix and order a pilot bearing seal. Done.

 

i can't help it, I'm broke now. they have one for 130$ there, i just need to know about proper sizes so i can get the right one

 

oh, and they have those calipers listed for 91.99 right now remanufactured.

don't get me wrong, I hate autozone as much as the next guy, but they do have quite the list of parts

 

I ordered that 91.99 caliper 3 times and every time they sent a non-turbo caliper even though the told me it was a turbo because that's whats in their system.

You didn't say n/a or turbo so I can't tell you what size you need, either way s4/s5 will work so buy the cheaper kit. If they show different sizes between s4/s5 then I would not even buy it.

 

i would use the s5 parts because it would for shure mate up with the input shaft

 

The input shaft is the same s4/s5.
