Okay, so I just learned that the ***** joints in the s5 LCAs are non replaceable meaning needing new LCAs.

Solution : s4 LCAs with replaceable ball joints.

Okay, thats fine. Anything else I should know of for my s5 before my friend scraps his s4 parts car? :P

 

S5 sway bar end links are plastic, S4 are metal with easily replaceable bushings.

 

And I believe you need those end links if you use S4 control arms.

 

thanks for the headsup
