If they haven’t been done already, all stock relieved bushes can be replaced with solid poly aftermarket items.
That’s front control arms rear position (aka LCA), rear trailing arms forward position, front (hydraulic) & rear diff bushes, pitch stop and gearbox mounts.
The latter two I’ve upgraded to Group N and its not too noisy in conjunction with stock engine mounts, which I have a spare set of for when the time comes.
I have AVO caster offset LCA bushes (works best with pokey rims, stock might rub inner guards, KCA399 adjustable rear upper outer bushes to correct rear camber from slight lowering, and absolutely essential: AVO HD rear swaybar mounts, yes even for stock swaybars.
And a solid GD STi steering uni joint.
If you’re lowering or raising the car or are replacing bushes, be sure to reset/ re torque all lateral arm bolts at static height eg on ramps or over a pit, otherwise the captive bushes with be under torsional load which can preload the suspension or lead to torn bushes.
Thanks Ben, great info. Looking to maintain stock ride height, and don't want to go too tight/stiff/firm with things, as my partner will be driving this a fair bit (and she puts up with other cars of mine enough that rattle the fillings out of her teeth). Running stock swaybars.
Do you have any experience with the SuperPro KIT209K? I don't hate the idea of a 'in one fell swoop' kit, and one of these might be the go if it's not going to contribute too much to NVH.
Whilst I've got you, any ideas on sources for a new set of Bilsteins? Found a set on Amazon for around $1,600AUD shipped, which doesn't seem horrible. I know people seem pretty keen on the idea of coilovers, but I've been pretty happy with the standard setup, and am not tracking this car.
