R32 Gt-r Rear Swaybar D Bush Size

[No Crust Racing]

Too wide across the 30mm measurement. As in the lips on the bush, sit a bit too far past the edge of the bracket.

Also too wide across the 33mm measurement, such that it's quite difficult to get into the bracket. I could remove material in that direction but would still have the issue with the lips sitting too far out across the 30mm measurement.

And what specifically upsets you about the lips being a longer way out than flush? Ultimately, it isn't going to matter much.

[No Crust Racing]

Ability to move around inside the bracket back and forth as the lips are not being used to assist in retaining the bush. I assume though that most of the force used to keep the bush in the cup comes from being pressed against the car itself by the bracket.

I'm going to grab the bushes and quickly re-test them on the way home. From memory it was a good 1mm per side that they were too wide.

Thin down the outside and jam them in.

Surely there should just be a damn bush that fits when everyone talks about this being a "bolt on" mod. Nobody else seems to have ever mentioned changing brackets or modifying bushes.

I'm also considering that if I thin the bush too much it could wear through/tear at those thin points rather than just using the right bush/bracket.

That's what the grease is for.

Plus.....these bushes don't cop of a lot of load in real terms. Up-down certainly, but lots less load fore-aft. It's in the nature of how the loads get applied to the bar at each end. Up and down.

[No Crust Racing]

Valid point.

I will re-test them on the way home. Just annoyed that this is supposed to be such a simple mod yet nobody has documented this which makes me think I'm missing something, wrong bracket, requires certain bush, etc.

Putting one of these into my S13, but unsure what D Bush to buy. SuperPro has them up to 24mm, but the bar seems to be 25mm (admittedly measured with adjusting shifter with measuring marks, tape backs this up but both could be 1mm out). I've also read some people state t's 26mm. Nolathane lists odd sizes.

Can any shed one some light on this?

Also do I need to use grease on the bushes when installing them? Seems to be a lot o conjecture around this also.

A standard rear R32 GTR anti roll bar has an outside diameter of 25.4mm or 1" in old school imperial. Says so in the service manual.

Sounds right, measured with verniers, The issue is bushes.

So these should come in 25mm as well but don't appear to?

[No Crust Racing]

I got those in a 25mm, I'm going to pick them up now and re test them and see if I can shave them a bit to fit.

Sick of chasing it up.

Just bought new brackets from Pedders for $8 that fit the bush perfect.

[GTSBoy]

Cross your fingers that they line up with the bolt holes on the car! The reason I slimmed down the front bushes on my car is that there wasn't room to fit a D with a bigger size between the stud and bolt hole. Any bigger D bracket I tried (not that I did) almost certainly would not have lined up with the fasteners.

[No Crust Racing]

I had the bracket with me. Bolt holes line up.

From memory nothing was in the way but I'll find out later.

[No Crust Racing]

Just did quick test fit. Brackets will fit car.

Just hit them with some primer and will satin black them later because I don't like the natural colour.

If I get a chance I'll fit the rear bar later but have been playing daddy day care while the missus is sick and out of comission.

[Sinista32]

A simple an easy replacement upgrade

[No Crust Racing]

Done.
