What suspension parts on a Civic Si are different from those on an EX? I will be doing a 5 lug conversion soon, and I am considering swapping in any Civic Si suspension components that are different from those on the EX.

springs are stiffer, and has rear sway bar, and thicker front sway bar. i think thats it.

if you're doing a 5 lug why are you concerned about SI suspension, if anything you will need some ITR stuff........
The SI has a front strut tower bar ($30.00) a sway bar that is believed to be too big, and no rear sway (and different shocks/springS)

The Type R suspension doesn't fit an EK, so I can basically just use the Type R brakes. The Civic Si has a 26 mm front swaybar and a 13 mm rear swaybar while the Civic EX has a 22 mm front swaybar and no rear swaybar. I heard that Civic Si LCAs are lighter than those on the Civic EX. How about the upper control arms? Are they the same or different? I also read something about forks. What are forks? Where are they located, what do they do, and how are the Si forks different from those on the EX?

u can use the itr springs. the front struts from the itr will work but the rears will not. the forks are where the front struts connect to the lower arm, i don't think the ex and si's are different. i think the only diff between the si and ex suspension is the swaybars and springs.
