R31 17" Wheel Fitting Problems

[sweefu]

Hey all,

I have a regular Australian R31 4 door, series III .. at the moment it has the stock wheels on it. I have just cheaply picked up some 'RS GT' rip offs, 17x7. They have a 225/45 on the front and a 245/45 on the rear. The thing is i don't know the offset. I trial fitted them (don't have wheel nuts until tomorrow) and they are going to rub on the front strut. What can i do to rectify this? A spacer? I'd prefer not to buy new tyres if i can help it. Pictures enclosed.

Thankyou.

May have found the offset ... 42? So, if the offset of my skyline is 30 .. what do i need to do to fit these wheels on? Run a 15mm spacer? Or could i go a 20mm?

Any help with this would be great, thanks!

Buy 20mm bolt ons. Dont buy slip ons. Just jap sell them i think

Thanks for that mate, J Racing here in Canberra has some in stock they said, for $80 - $90 each. Just Jap are out of stock unfortunately. Do you think that 20mm will hit on the guard? Or would i be better to switch to a 215 wide tyre? I'd prefer not to if possible.

225 is the widest I'd go on 7" wheel, 245 is ridiculous.

You can get away with running 15mm bolt on spacers. I suggest you try to look for wheels that fit (low offset +25 or less).

Yeah i agree 245 is stupid, but they're new and came on the rims and for my budget, they'll have to do for the moment haha.

I'm i've talked to a few local shops and they say a 20mm bolt on spacer on the front would be the go, so i'm not sure if i should go a 15 or 20 mm now? I dont want them to rub on the front guards. Also, could i go a 20mm on the rear do you think?

Thanks for all the help, very appreciated.

I know R31 club is better for this sort of thing, but i dont have a proper email address, and cant get one for another few weeks, so that means i can't join up. So i'm sorry to keep bothering everyone with this!

Can someone confirm for me please? I'm not sure if i should get 25mm or 20mm bolt on spacers? Both are similar price and are 'Billet Aluminium'. Am i right in thinking that a 20mm spacer will make the offset 22? (42-20 = 22?) - Sorry if this is very wrong its the first time i've had to wrap my head around wheel offsets and everything like that.

So if the offset of my R31 is 30 a 20mm is the way to go?

Thanks very much, any help is greatly appreciated.
