View Full Version : Fitting FG XR6 wheels to my TW VRX?

As the title suggests, will FG XR6 rims fit my TW VRX?

I know that BA/BF rims do, but will FG fit too as I think the offset is different on the FG.

Also, the ones I am considering buying have average tyres. The XR6 rims are 17", so will my near new Achilles ATR Sport 225/50 R17 98W tyres be able to be swapped over onto the XR6 rims?

Thank you guys, appreciate it

From what i can google, the BA-BF falcon factory rim offset is +35 and the FG factory rim offset is +45mm
So, the FG rim would sit inwards 10mm more than the earlier rim.
Use a 10mm spacer and you'll be right.
I have BF rims on my car, they sit pretty nicely.

Not sure about offsets (I know BF was +35 as Old4g has said, but I can't say 100% sure for FG) but centre bore is also slightly different. Best bet is to get a centre bore adapter. Probably about $30 for a set of four on eBay.

I'm 90% sure that the FG rims are 17x8" so your 225/50/17 tyres can be swapped over fine. There'll be a little bit of stretch to them - particularly compared to standard as Falcons run 245/45/17 if I recall correctly - but nothing silly.

I had always debated trying a set of G6E wheels on my 380 but never found a cheap set close to home.

All AU-FG factory alloy wheels are around +35 to +37 offset

Ideally you would want to be using 235/45R17, being an 8" wide rim, but I can't see why you couldn't use 225/50R17

you MUST MUST get a center bore adapter. Offsets will maybe cause bad handling - body rubbing or police tickets, but a wheel that sheers off the studs because the wheel center was not transferring the load to the axle can end up in a ditch or a tree.

I went through this a couple of months ago and bought some 18" mags from a BA Falcon, yes they fit and a centre bore adapter is a must but due to the offset and a lowered car they just about ripped my flares off on heavy pot holes. Also for some reason the nuts wouldnt stay done up so needless to say i didnt stick with them for long. Personally if it needs adapters or spacers i would stay away from it. In the end I ended up with 18" Hyundai Veloster Turbo mags which have a 49 off set and the same centre bore so no adapter needed and the nuts stay done up.

Would this be a suitable bore: http://www.ebay.com.au/itm/4PCS-Wheel-Spacers-Adapters-5X114-3-1-2x20-Studs-38mm-Center-Bore-71-5mm-New-/261888352682?hash=item3cf9c321aa:g:LGIAAOSwNSxVVZn Q

If not, can you point me to one that is?

Spacers aren't a good idea, and are also illegal.
You need to get hub-centric rings. Small rings that fit the centre bore of the rim you want to fit, and reduce to the hub size of the vehicle its being fitted to - essentially filling the gap in measurement between the rim centre bore and hub bore.
Similar to these (http://www.ebay.com.au/itm/4-X-70-1-67-1-ALLOY-WHEEL-LOCATING-HUB-SPIGOT-RINGS-FIT-MAZDA-3-5-6-/171892535854?hash=item280597f22e:g:VA0AAOxyFrNRxFN a). You will, however, need to confirm the centre bore of the FG rims, but the centre bore of Magna hubs are 67.1

If you are swapping the tyres over, I presume you will do this at a tyre place? If so, then any reputable tyre store should have the hub-centric rings in stock. It is a regular thing if you go aftermarket as they are made to suit the biggest bores. As Ammerty said, spacers are illegal.


If they are 35+ offset then the 225/50 should be inside the guard, just and unless you have lowered it, there shouldn't be rubbing issues.


Falcon centre bore is 70.1 so you will need a 1.5mm hub-centric ring like Ammerty linked but as I said above, any reputable tyre centre should have them.

Okay that's handy to know. Yes, Kmart Tyre & Auto here in WA will be doing it (if I buy the XR wheels)

In stock?

Possibly but not certainly.

The local Bob Jane T mart did not have my size in stock a few years back when I tried for my recently purchased aftermarket wheels on my R31 Skyline.

He even went to the trouble of looking through his second hand stock with no luck.

I had to buy from the UK via Ebay - cheap, good quality and quick postage.

So ring your store or drop in first to make certain.

Just make sure you fit them and ignore anyone telling you that you don't need them. - YOU DO.

This could potentially turn into more of an effort then I first thought haha.

I've been having a chat to a few other about this, and one said that even with bore centres, the difference in offset from from my original VRX wheels to the XR6 wheels could put excessive strain on the wheel studs and over a few pot holes cold in-fact snap them off.

Thoughts?

My first ever job selling 20 years go (before I ended up selling cars) was in a wheel and tyre store - non franchise.

The general rule was not to fit front drive wheels to a rear drive car, and vice a versa.

Front wheel to front wheel ok.....rear to rear ok.

My personal experience on my own cars was not to cross swap.

Any change of wheels was always same type to same type.

The hub centric rings will take care of most potential problems, but the geometry
changes produced by differing offsets are not predictable without trying it out IRL - or computer modelling.

You are taking a risk, and one that I would steer clear of - which may be an appropriate figure of speech.

Have another look at post #6.

ANY wheels you buy that aren't OEM will most likely have a different offset and will require hub centric rings.

Truth be told I didn't even run hub centric rings for the first year or two I had my wheels - the tyre shop pointed it out to me but said not to worry. I wouldn't advocate this position, but hey, it's what happened to me.

I've also driven on some shocking roads (i.e. Bruce Highway after the 2011 floods) and my studs didn't fall off.

I wouldn't worry.

If you where putting pre AU wheels on id be worried about snapping studs as they have a zero or low offset
