A GSR K-frame is no different to your GTi K-frame Shauny!
GSR/ GLXi Lancers and GTi and M21 Protons all have the same K-frame and crossmember.
Keep the GTi setup as its the same as EVO 2/3!!! Only the hubs are different in GTi;s as they use the 4x100 PCD 13" hub and mount the tie rod end from the bottom, not the top as the EVO 2/3. I've just gone through this same thing with a mates conversion for engineering. 2 weeks ago I did an E2 full front end suspension and K-frame conversion into a GSR, and last week did comparisons between GTi vs EVO 2/3 front suspension. Tomorrow I'm putting GTi suspension into a CC Lancer coupe.
(busy boy). You can read up on the findings here:

http://orion2001.gallery.netspace.net.au/Angelo?page=3 to show you and others that GTi suspension, swaybar, link and strut setup is the same as EVO 2/3. The lower control arm and hub are different.
Yeah Libz, if you have the E2/3 shocks and E2/3 swaybar then there wont be any issues. I thought you meant using E2/3 swaybar and linking to GSR/E1 lower control arms.
