Hi all,

Precursor: Only answer if you know for sure. Only answer with answers, not opinions. Cheers.


Looking at getting these wheels. (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=300788053823)

20x8.5. Offset ET40. Centerbore 73.1.

Will these fit? I presume I'll have to get hub rings. If so I'd rather get aluminium ones rather than plastic. What size rings will I need? Is there anything I should know/be concerned about when fitting this size wheel?


Thanks,
Sam

67.1mm to 73.1mm hub rings. Look at these and see if the seller has relisted same. I ran them on my Magna and 380. http://www.ebay.com.au/itm/Hub-Centric-Rings-OD-73-1mm-ID-67-1mm-Aluminium-Alloy-/200826883153?pt=AU_Car_Parts_Accessories&hash=item2ec2370c51

If you run 245/35/20 tyres (which would be my recommendation) you may very well need to roll the rear guards.

It will be a tight fitment but will look tops.

Plastic hub rings are better just as a tip. But you can google that.

You will definitely need hub rings (also called locating rings).

245/35/20 would not fit on my 380 without serious rubbing on the wheel rear arches, so I went for 245/30/20 which fitted no probs.
That's with Kings lows on the rear and superlows on the front.
But they were +36 ET not +40, that is mine "stuck out" further than those in the ad. Which means that 245/35/20 +40 ET might just fit on your 380 without wheel arch rubbing problems, but then again they might not clear the suspension components. Hard to tell without a test fit, which is obviously pretty difficult when you are looking at Fleabay rims.

I just got my 20's with +35 off set wheels machined down to a +40 offset (so I can go lower;)) to reduce rubbing in the front with 245/35 rubber and it made a massive difference. My car is on superlows all round as you saw when I was in Melbs for MM. I've hardly heard it rub with the +40 offset so I'd say you'd be fine.

The tyre size Red mentioned is pretty popular too so you have a bit of variety in terms of tyre choices also...

Yeah but you didn't roll your rear guards did you Kim?

I reckon it'd only be an issue if you had your guards rolled AND you were getting rubbing.

Yep, I didn't roll my guards.

I reckon the OP is asking what will fit without rolling the guards.

Plastic hub rings are better just as a tip.

Had a quick look into this. All I could glean is that metal rings can over time corrode a little and become stuck on the hub. Plastic obviously wouldn't have that issue. Is this what you were referring to?


So what I have gathered from responses:
- need 67.1mm to 73.1mm hub rings
- 245/35/20 tyres seem to be the most recommended but may result in me needing to roll rear guards

For a little more info, I'm currently running superlows all round, like Kif :happy:


Thanks for the solid advice so far :thumbsup:

For my 2 cents worth rolling the rear guards is not straightforward as they are double skinned.
Several bodyshops wouldnt do mine as they said they would crack the paint.
There is a thread on this and I followed Foozercools tip to heat up the paint when I did it myself. Still cracked a bit but I superglued the odd flake back on and hardly notices.
I only have 19's with lows

Yeah the metal ones are misshapen easily and they have no advantage over plastic

In that case, get your rear guards rolled and you'll be sweet with the 245/35 series. I had my guards done by a professional guard roller for $120 for both rears. No dramas at all. He even came to the house.

Yeah getting them rolled isn't an issue. My best mates brother has a business that does guard rolling and I know he'd be able to do mine no problem. He heats up the guard before he rolls it as well, so paint cracking generally isn't something you have to worry about.

Thanks for the info. Just gotta decide if I definitely want them and gather the funds now :)

Why wont anyone go down the 22" route again?
