Hi Guys,

I fitted eccentric bushing caster arms into my R33 recently and thought I would do a very quick write up on it (my first write up so take it easy!)

Tools needed:

- 17mm socket and accompanying ratchet

- 17mm spanner

- Pry bar to move the suspension/wheel forward to accommodate for the change in suspension

- Soft mallet to make things easier if things are stiff

- Jack

- Jack stands

Time needed: 30 minutes max for a first timer includes finding the right tools, jacking up and packing everything away.

Info: An eccentric bushing or bushing with eccentric crush tube is one which offsets the position of the bushing for adjustment - In this case, caster.

Before VS After:

1) Jack the car up and place stands under it. Place the stands in a place which will allow you to get under the front wheels safely an with ease

2) Undo the 17mm bolt using two spanners or a ratchet and spanner on each side from the front busing

3) Undo the two 17mm bolts off the studs on the lower control arm

4) Push the caster arm up and out of the way

Installation is reverse of removal however depending on how your eccentric bushing is set you will need to move the wheel forward or backwards to get the holes to align. I put my eccentric crush tube in the position that shortens the length of the caster arm. This meant that I had to push the back of the wheel to the front of the car.

I also have a video of the old bushings in the stock caster arms which is still uploading but I'll post here when it's done.

Let me know if there any improvements for next time!

Cheers

Just an update on this

I got stung pretty badly by the alignment shop because of these bushes. They said it took ages to adjust therefore cost more because they kept having to remove and reinstall.

This confirms my theory that eccentric bushes are good in theory but less so in practice. I used to run Whiteline eccentrics in the rear (spent ages pressing out the OEM bushes too) and ended up replacing camber and traction arms with adjustable items, much easier to align.

Yep - The alignment shop wasn't very impressed nor was I when it came to paying the bill.

He said "The price difference between the two is good but when the arms have to come off this many times you start to pay a lot more for labour so it works out the same anyway"

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
