S4: lighter, slower, rectangle tailights (n/a secondary ports opened by airpump(i think))
S5:heavyer, faster, bubble tailights (n/a secondaries open from backpressure off the main cat)

weight isnt a huge difference but its there, thats about all the major differences

next time search, it isnt that hard to find, especial something so basic.

why do you ask anyways?

depends on quite a few factors, mainly on how much you can find the s5 parts for. The tail lights alone can run up to 200 bucks

Interior of S5 is black, compared to the grey in S4. The turbo exhaust ports are same sized in S5, S4 has one smaller than the other. S5 has the better looking side moulding imo, and front bumper. S5 has lighter rotors I think. I think S5 has a electric OMP, whilst the S4 has a mechanical one (not entirely sure). The s4 uses clutch packs for the LSD, while the s5 uses a viscous type LSD. And the S5 had an aluminium bonnet as opposed to the steel ones in the S4's.

Yes the S5 spoiler does fit.

Side moulding as in... the mouldings that go all around the car... err... hard to explain... Look at series 4's with a bright colour. Like white, or red. You can see a black stripe that goes around the car. That's what I mean. S4 is all black moulding, where as S5 is coloured the same as the car. Also S4 has black mirrors, S5 has painted mirrors.

Oh, and I just remembered, I think only the S5's had the DTSS. Forgot what the abbreviation stands for (Dynamic traction stability system or something?) Passive rear toe control system where under load, it will ch ange your toe in/out depending on which way your going. I found a really cool vid on these forums one time, someone doing a donut with their S5, and you can see the suspension moving. But some people will tell ya it's a pain in the ***, and to get DTSS eliminators :/

How about you stop spreading misinformation.

ALL FC's had DTSS except for a rumored set of JDM ifini ones or mazdaspeed or something... .but.. for all intensive purposes... ALL FC's had it.
