Wheel change but unsure of offsets???

Hi guys.
I dont really have a clue about offsets so i'll try my best to explain what i wanna know & hope someone can help.

I currently have a VW Bora 4motion on a set of 18"Audi Rs6 replica 8j 's with an offset of et35 & a PCD of 5x100 with Nangkang Ns2 215/35 rubber.

I have found a set of 18" 8.5j wheels with an offset of et45 & a PCD of 5x112 that i am thinking of buying.

I will be running the same rubber.

But what i want to know is.... What the difference will be between the new Wheels & my old ones???
Also what size adaptors i will need??

Any help & advice would be really appreciated.

(Have also posted this over on WheelWhores)

Thanks in advance,
Mike [:)]

the off set for std 4mo wheels is 42 if that helps to start
Thanks for the reply.

Is it 'the bigger the number,the more it sticks out' ? or is it 'the bigger the number,the further into the arch it sits' ???

Sorry im a bit thick,lol. [:$]
With an adaptor of 15mm your new wheels will be ET30

They'll poke out 10mm more than your current wheels while giving the same clearance on the inside for the suspension etc........all this is assuming that your not running any spacers at the minute.

Right ok,now that was the second part of my question,lol.

I currently have 30mm spacers on the rear & none on the front........ BUT i am looking for another 5-10mm on the rear & 10mm on the front.

Any advice on this please? Cheers Patch.

So if i got 30mm adaptors that would give me the 5-10mm im looking for wouldnt it? [:cool:]
The wider wheel will give you 10mm more poke up front used with a 15mm adaptor,to get the rears to poke out 5mm more than it does now you'll need 40mm adaptor giving you ET5

So that's 15mm up front giving ET30.

40mm at the back giving ET5

That's quite a lot of poke at the back.

17mm more poke than my old CSL's,are you sure you want that?

See less See more
would give u a final et of 15 would poke about 8-10mm
Excellent! [:D]

Cheers Patch [Y] .

EDIT:

Iv got quite a bit of Negative camber on the rear so shouldnt be a prob.

As i say,iv got 30mm spacers now & could go another 5mm easy,lol.
