Can anyone comment on upgrading the swaybars + tie bar on a DC2 VTiR with slightly worm stock springs/shocks?

Or should I save, and do my entire suspension in one hit? I'm planning on getting coilovers (undecided) - but then redoing the entire suspension. Front/Rear Struts, Front/rear Sway bars, Tie Bars. Will I need LCA if I'm going Coilovers? Then finally the coilovers and maybe misc stuff like C-Pillars etc.

I dont mind doing it in one go, but obviously doing it in two steps would be more fun for me as I'l be able to have the $500 much sooner than the $3000 for the entire setup.

Thanks
