Anti-roll bar bushing 23mm or 25mm?

[Razmann4k]

Hi, I've seen comments on the forum about the 172/182s having a 25mm front inner ARB bush, and the 23mm's being the non-Sport. However, the part numbers seem to be identical: 7700847383
In my country I can find one that says it's 23.5mm, I just wonder if it's correct or not. And if it's not the right part, would it still fit with a little persuasion?

IIRC inner bush is 25mm outer bush is 23mm.

That's what I read, however the part number is only for the inner and both 23 and 25mm bushes show up.

These are the one's you want, they match the OEM number too:

Thank you, unfortunately, these are not available in South Africa. I'm just wondering if the one that is 23.5mm would do, perhaps I could file them a little if need be.

Don’t see why not? 🤷🏻‍♂️

If you've got a non sport and want to fit a 23.5mm, it'll be a squeeze getting the bracket to clamp properly but it should be do-able as it's only .5 bigger than stock. But if you've got a Sport and go to fit a 23.5, it'll be 1.5mm too small so your antiroll bar will be really slack potentially.

I have a 182 w/ Cup chassis, and I want to replace the old cracking inner ARB bushes, but the 25mm bushes are seemingly unavailable, that's why I'm asking.

Mind you, the 23.5/25mm measurement is the inside of the bush where the ARB goes, the outside seems to be pretty much the same size.

Right I get you. Like I say you could fit the 23.5mm's, but they'll be smaller than standard so the handling may suffer.

I edited my reply to clarify.

Right I get you, yeah you should be able to fit the 23.5's then, it just might be a squeeze getting them on. As long as they don't tear during fitting, you should be fine.
