The GT Spare Wheel /Tyre Solution- "The Gnome Spare"

AusS550-GT said:

Nice work, I was waiting to order a spare, so this answers all my questions.
Just out of curiosity, are there any storage locations on the side of the boot to store any toolbags or similar such as @mwizz suggested?

I have just ordered the cargo net from CJPP - I am intending to use it for the "extras"

How big is it?

It covers the full width of the boot at the very back end (the boot entrance). If you have a look at the CJPP website there is a short video which should answer your questions.

Hey guys, because I'm a nice guy, I have a free offer for you. I finally was able to get a jack from a wrecker and my mate threw in the foam base as well (I had already bought a new one from Ford)

So, I have one foam base I'll let go for free, first in first served so drop me a pm and it's yours. I'm located in Norwest Sydney and I'm happy to meet you in the hills area somewhere.

This thread has been started as a reference for 2015> Australian GT Mustang owners looking for a solution with regards to the spare tyre. Due to the fitment of the large Brembo brakes including the staggered wheels, Ford has only supplied the air compressor and a sealant canister as the solution for a flat tyre.

For many that live outside of the metro areas, for peace of mind or the sheer convenience of being able to change a flat tyre instead of calling a breakdown assistance number, the “Gnome spare” is the perfect solution.

This thread is a condensed version of the original thread found with the following link-

http://www.mustang6g.com/forums/showthread.php?t=41050

All credit is to a forum member known as “Gnome”, thus the name given “The Gnome Spare”. Gnome / John researched on behalf of many here and through his hard work finally came up with a solution which each of us can enjoy.

I will not go into all the technical pro’s and cons which has already been discussed at length in the original thread. This thread is simply to inform others of the steps required to having a “Gnome spare” for your very own Mustang.

Below are some quotes from Gnome / John in the original thread. Following after is a step by step guide on what is needed and how to fit the complete kit ready for usage-

Quote “Gnome”-
OK here is where I am up to on my search.

Simmons do a 19 x 7.0 ET + 20 that they think will fit over the Brembos, I am organising a test fit with them. There is a 175/60 R19 tyre available from JAX tyres that should fit this rim.

Diameter of the tyre is 693mm compared to 703mm on the standard rear tyre, this equates to 740 revs per mile compared to 730 revs per mile on the standard one.
I have asked my dealer to fire off an email internally to Ford to get confirmation from them on what speed and distance limitations they would place on using wheels with this sort of diameter difference.

Quote “Gnome”-
Yes the plan is that it will work on the front and the rear. Ideally I was after a 6.0 or 6.5 rim, but the 7.0 may also just fit the depth

(Edit- Gnome is saying that the spare wheel can be used on both the front of the car and also the rear of the car independently)

Quote “Gnome”-
I also had an answer back from the service manager at my dealership today regarding the effect on the LSD by having two different sized rear tyres. The reply was as below.

Quote:
I spoke with my Ford Service Engineer (FSE) last week about this and the simple answer is Ford don’t have a position on this as no testing has been carried out on the rim your proposing to use.

His best suggestion was 10.5 +/- revolutions per mile should have little to no impact. Especially considering it is only a “in case of emergency” arrangement.

What you are proposing should be fine.

The steps involved to the spare wheel / tyre solution-
“The Gnome Spare”​

Call “Tempe Tyre and wheel centre” who are based in Tempe / Sydney on the following number- 02 8577 8577 or Email-[email protected]

You need to ask for the 2015> Mustang spare wheel and tyre, they have this information on record. Also make sure to ask for the wheel nuts which are included in the package as the spare wheel cannot use the original Mustang wheel nuts.
Expect to pay approx $550 delivered dependant on your state and address. Tempe Tyres use their own courier and deliver to your door Australia wide.

The next step is to purchase from a car wrecker a “Falcon FG” jack kit. Make sure you not only get the jack but also the foam base and all other components. Expect to pay somewhere from $50 > $100

The next step is to purchase a couple of wheel nut sockets and a socket extension brace / bar from a tool supply store or auto store. The sockets required are 21mm for the original Mustang wheel nuts and a 19mm socket for the Tempe tyre supplied wheel nuts.

The last step is to purchase from either a “Bunnings” or any other leading hardware store is a small nylon tie down strap. This strap will secure the spare wheel in the wheel well; in the event of a roll over the spare tyre unsecured can be fatal.

Firstly remove the original compressor / sealant canister kit from the spare wheel well in your Mustang. The complete spare wheel well needs to be empty.

Place the complete Falcon FG jack kit / foam base in the wheel well making sure to fit the towing / recovery bolt from the original Mustang compressor kit into the FG Falcon foam jack kit base.

Place the Tempe wheel nuts including the 21mm & 19mm socket in the wheel well. You can use a small cloth pouch to hold the sockets and nuts and to stop them rattling around. Place the socket extension wheel nut brace also in position.

Place the spare wheel in the wheel well, at this point you may need to trim some of the Falcon FG jack foam base to ensure that the spare wheel fits snug and does not protrude higher than needed.

Pass the nylon tie down strap underneath the original bracket which secured the compressor kit, then up and over the spare wheel spoke, tighten the strap until firm.

The Gnome spare sits a little higher in the wheel well making the rear spare wheel cover sit approx 10mm proud from the floor surface when closed. The easiest solution is either a rubber or carpet trunk mat which smooths out the imperfections creating an even look.

Some people have commented that maybe even carrying a small block of wood or plywood assists in raising the rim / wheel in the event that the tyre is completely flat. Some have reported of the problem of the jack not fitting underneath the body of the vehicle when the tyre is dead flat. The small section of wood allows the car to raise approx 20mm when driven on thus allowing the jack to fit underneath the body of the vehicle.

Now enjoy in the knowledge knowing that you are covered in case of a flat tyre, no need for breakdown assistance or even new tyre pressure sensors that have been destroyed by the tyre sealant. “Thanks Gnome, thank you”

Is the spare tyre jack kit from a BA Falcon the same as a FG Falcon kit?
Can get one for $50 from local wrecker.

Thanks found it. May consider ordering one when I next put in an order.

Thanks [MENTION=22406]mwizz[/MENTION]. I didn't think so from photos but I was hoping so!

That's a good idea actually.
I just made an order at CJ's so will consider it for my next order.

I have done a bit of looking around and the ones at CJ Pony Parts are $US66 plus shipping. Ali Express has some cargo nets for the Mustang which look pretty similar for $11.16 AUD and free shipping. I think they are worth a try at that price.

You can get the genuine article from local Ford dealerships for $48 (once they remove the $15 fitting charge).

Ordered my wheel/tyre yesterday, $575 for delivery to Brisbane and I should get it mid-late next week.

Thanks Gnome for the work you did

Got a jack and base from an FGX today, hopefully it's exactly the same as an FG.

Also just got this set from trade tools, should do the job. $66 for the pair. Socket set includees 17, 19, 21 and 22mm.
The wheel brace is not quite as short as the one shown but I'm not too worried.

Your correct Mark $11.16 not bad, Fits well, checked out the one from Ford $90 , Can't really tell the difference

Sorted out the lowered car issue today with the jack not fitting. I did consider cutting smaller pieces to fit in with the spare tyre but I don't think they were going to be quite long enough.

This solution works just as well and you can only see the wood when your head is right inside. Just keep a knife with the wheel well to cut the cable ties :-)

I ordered one tonight and even got a $2.00 US coupon for starting an account and it ended up costing me $8.50 AUD delivered so will wait to see how good it is when it arrives. The photos of it look the same quality as the Ford one.
