Offset is how far the hub of the wheel is from the centre of the wheel. So basically the lower the offset, the more dish you will get. Or more spoke concavity depending on the style of the rim. But this also means that the wheel in general will sit further out the lower you go with offset.

In general lower offset = tough, but more effort involved in getting the wheel to sit right if you go too low (guard mods, camber, stretched tyres).

For your car id go something like 18x8.5 front and 18x9.5 rear. With maybe 35-ish offset for something reasonable.

most ppl want the wheel to completely fill their guards.

the more towards 0 (well...negative really) acompanied by width, the more it'll fill it out.

google for 'offset calculator' to see the difference new rims will make from ur old rims.

this is my car below with

18x10 +18 rear

18x9+20 front with a +25mm spacer...effectively making it 18x9 -5.

ofcourse you'll need to roll ur guards and if u keep going flaring your guards.

so basically figure out what others r running on the 34's with a guard roll (only costs $50 a corner to do) and go for that is my suggestion.

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
