ALLOY FRONT CONTROL ARMS! IM LOSING THE PLOT

[turborunner]

would like to do this to my v2 gf8 wrx with v7 sti gold rims, have the v4 sti gc8 alloy arms with the links 1. is that all i need to do the conversion, would probably not do the free caster mod(2. whats the benefit of do this?)

3. does this mod need a cert?

4, whats the pros and cons of doing this mod?

5. is this mod harder to carry out than changing the backing plate on rear to accept 2pot brake calipers

thanks for your help

1) rims are irrelevant to this discussion, you need the lower arms, with the concial insert and the balljoint. The bolts are all the same. You DO need to swap your dog bone drop links for the spherical sort.

2) do your own reading on caster - googles your freind. Dont take offence but if you dont know what it does, dont do the mod.

3) No cert required for an alloy arm swap or free caster mod, anti lift kit mod, OR a roll center adjuster kit thankfully.

4) alloys are thought to be lighter.. they are NOT. what they are is a bit stiffer and if you can get later GD or Spec C ones even, they have slightly better geometry. Again research geometry changes to work out what it does.

5) Both modifications are reasonably simple. As per the NASIOC link above... there are lots of how to's. If you have the right parts for the rear 2pot brake modifcation its not more difficult IMO.. just different.
