The S5 seems to have higher skid pad G's than the S4:

Does anyone know what the differences are between the two series in terms of suspension?





I also want to upgrade to the racing beat package down the line with some KYB's what kind of G's can I guesstimate getting?

 

the base s5's have different springs, and shocks. other than that they are pretty much the same.

 

From memory the swaybar links are different. The s4 ones use a rubber bush and the s5 use plastic.

But parts are interchangeable between the two.

 

Thanks guys, so no major differences that can't be adjusted with aftermarket (or even oem from the S5). I was afraid there was some difference in geometry or something.

 

They both use rubber bushings, but the end links themselves are plastic on the S5 and metal (steel?) on the S4.



Also the S4 control arms have replaceable ball joints (held on with 2 bolts), while the S5 does not.



Not that either of these affect performance, but noteworthy nonetheless.

 

Thats what I meant...my grammer seems to be slipping a fair bit, well if I had any to begin with it would be slipping...

 

mazdatrix has nice sets of link available which are supposed to be much more durable than either stock s4 or s5 oe components

havent looked at too many s5 ones, but the s4 ones are all shot

 

If you don't want to spend $133 on sway bar end links, you could always use the S4 end links with new polyurethane bushings (less cost).



I used the bushings from Energy Suspension, they're super easy to replace, no press needed. Immediate noticeable improvement.

 

yeah? thats nifty
