**** from the top of my head lol :
GSR/EVO I front swaybar is a lot thicker and stronger/ heavier duty than EVO II/III.
GSR/EVO I front swaybar and lower control arms are a lot more bountiful in parts. Even normal CC Lancer use the same lower control arms.
GSR/EVO I front swaybar bolts via links onto the front lower control arm.
GSR/EVO I front lower control arms are strong. It is very rare that you will ever break the tabs off.
GSR/EVO I tie rod ends and front hubs bolt the same way as normal CC Lancers do (e.g. tie rod end under the hub and castle nut on top)
GSR/EVO I use a front hub with the number 14 cast into them.
GSR/EVO I front wheeltrack is: 1450mm
EVO II/III front swaybar is a lot thinner and lighter than GSR/EVO I. It also uses different D-brackets on the k-frame.
EVO II/III front lower control arm does not have a weld on tab on it and in fact does not have the swaybar connect to it at all.
EVO II/III front swaybar uses long sway bar links that bolt onto tabs that are welded onto the strut.
EVO II/III front sway bars and tabs on struts have been known to snap and break off.
EVO II/III tie rod end bolts up upside down to normal CC Lancer/ GSR/ EVO I (eg tie rod end on top of the hub and castle nut underneath - therefore EVO II/III use a different hub than GSR/EVO I)
EVO II/III front hubs have no number cast into it.
EVO II/III front swaybar and suspension setup is a lot rarer and difficult to find replacement parts for.
EVO II/III front wheeltrack is: 1465mm
* It is said that the EVO II/III front suspension and steering setup is a bit more responsive than the earlier GSR/EVO I in STANDARD form.
* There's nothing stopping somebody from modifying their GSR/EVO I front suspension and steering setup for added wheel track and castor by using aftermarket parts (eg. Whiteline front lower control arm castor bushes KCA317X)
* Generally, it is not necessary to change the front swaybar in a GSR/EVO I because they are already quite thick and h/duty. In fact aftermarket suspension suppliers usually only list a part for the rear sway bar (eg. Whiteline BMR56 18mm, or BMR56X 20mm).
* Another thing you can do is use multi-adjusting front strut tops like K-MAC Camber/Caster tops. You can get any angle and castor adjustment with those beauties!
* Comes down to budget, the suspension setup you need for your competition car, and personal choice really.
