My turn... I've been into rallyong since before I got my drivers licience, and that was in 94 (I'm not doing the math)
Traditionally, nobody ever gave too much attention to the swaybars as there's so much undulation & off camber corners here in NewZealand that stiff swaybars were not high on the priority list. Myself with a 2001 Bugeye hatch, I'm not going to touch the front swaybar unless I get Sedan lower arms and have to... as for shocks All I intend to do is get some new KYB shocks, Maybe you could think about STi struts (the red KYB inverted things) but I don't have that kind of budget. as for the rear sway bar... I'll think about the AFTER I find out what the Australian made King Springs do with the Handling (and NOT BEFORE)
I'll do the Bushes as I go, as It seems pointless to go buying a full kit of bushes when 1/2 if not more of the aftermarket parts will either not have bushings but ball/Rose joints or have specially made bushes allready fitted to them... Bushes that dont com with parts... Gearbox mounts, Subframe Locking kits, steering rack etc.
Whiteline do adjustable arms for the ass end, & I will definately look into getting some. though I'm not too sure if "I" would chuck the plastic swaybar link for more rigid Alloy ones. as on gravel & rough roads... things NEED to move, so it could actually be an Idea to see if you can flip the arms, or swap from side to side so the link mount is on top & use a rose joint setup of somekind, but thats just a tought & I don't know if here's room to do it without going outside and getting wet right now.
I've already done My exhaust, thats a Must for ANY suby fan lol
though my own suspension will not be "that" tight, I'll still get a rear strut brace, front brace plus I'll get some under car braces.
If you really want to get the rally feel Fast, pull your seats out, this will allow you to rip your carpet & sound proofing out & then you can put your front seats back in and BBQ the rest!
