I've seen several sway bar companies (suspension techniques and whiteline) differentiate between S4s and S5s for their sway bars, but some don't (racingbeat).

I was looking into a whiteline front adjustable bar (because it's adjustable...) but they say it's only for S4s... what's the difference? shouldn't it just bolt up to my S5 fine?

the only thing I can think of is that where the end-links connect are different (S5 has dumb plastic end-links), in which case I'll be forced to get S4 lower control arms... darn

does anyone know specifically if the whiteline bar fits on an S5 easily or just if their different or not?

thanks.

 

no one knows anything about it?

 

hmm.. I've been thinking about using the s-4 end links on my s-5 car. This is a question that needs to be answered.

 

the stock ones are interchangeable between series...i don't see how an aftermarket one would be different but you might want to call the company to ask them yourself.

 

Well it's adjustable... So if the end links are the same/similar I don't see why not. But call them and verify.

 

Myk, the ST rear on my S4 is from an S5.
