I'm not sure if the Invidia has less clearance than other choices, but mine scrapes seemingly everywhere.

Question. As far as I understand, you want to get as many bushings as you can as long as they fit where the OEM part goes, such as the Whiteline LSD Inserts, Transmission, ETC. Or get OEM+ components like the STi LSD bushings, transmission mount, engine mounts.

What would be the complete list of bushings/inserts that I would be able to get. So far I have;

STi Transmission Mount
STi Engine Mounts
STi LSD Mounts
Perrin Poly Sway bar bushings
@Racecomp Engineering Rear Subframe Mounts?
STi Trailing Link Set?

STI trailing link set uses sphericals so it's not legal, FYI.

Alright, sweet, I'll remove it from my list.

You can replace these with poly bushings, just make sure they aren't metal sphericals:
- Front lower (well, we only have lower) control arms
- Steering rack
- Rear subframe to body inserts
- Rear lower control arm
- Rear trailing link

You already have all the powertrain mount stuff that I can think of.

I couldn't really find or I am not really sure what would be acceptable for the last two. I think I got most of the other bushings right?

I installed SuperPro front control arm bushings, the kit came with both bushings for each control arm

Steering rack and subframe to body inserts I have Whiteline, what you have looks pretty much the same as I recall.

On the rear lower control arm, I have SPC adjustable arms with Diftech delrin bushings. Not sure what the availability is on those now.

Can't recall if I'd found anything for the trailing arms, I don't think I've put anything in yet. Right now the car is kinda stuck in my shop waiting for me to install the oil pan and pickup.

I got verus rear LCAs with the poly bushing. Very expensive, but also very pretty. SPC RLCAs is what most people go with. Just make sure it's not replacing the bushing with a pillowball.

Ah, NoHaveMSG actually sent me the Whiteline Adjustable LCAs. I think those are good?

Whiteline LCA

Those ones are great. I had them before I moved to SPL. Now they are on the wife's WRX and, again, great.

Look good to me.

FWIW Cusco upper arms save a lot more weight and then do MOOG K90473 camber bolts in the LCA to subframe position. Cheaper, saves more weight, and gets more useful adjustment. Plus you can effectively narrow the rear track for more space to cones.

How do you feel about the racer x upper arms ?

Double the price of Cusco for no reason, IMO.
