Got the spacers installed today and sometime later will get the tyres installed also. There is a noticeable difference in the stance of the Gypsy -- because of the wider track and looks cool even with 235/75/15 Maxxis :-)

Here are some pictures.

Difference between OE studs and extended studs


The spacer mounted on the rear wheel with extended studs


The original/without spacer picture showing the rear tyre.


The picture showing the rear tyre with the spacer -- notice that the tyre is jutting out now :-). This will prevent any rubbing/scuffing of the bigger size tyre that I will be putting on soon.

Helo Khan bai,

How much cost those spacers? Off the shelf or custom made??

Thanks,
sadiq.

Khan bhai,
Will these studs be strong enough to survive otr's ?!

I've always been under the impression that spacers=no-no ..

Looking forward to your reviews soon!

In the spacer as you have mentioned, the bolts are the weak point.
You will need to make a spacer like the attached image in Stainless Steel.

You will have to use the original bolts and bolt it onto your drum/disc, There will be an additional set of bolts set in the spacer to which you can fix the wheel.
I had used this method in my drag car setups, after tearing through some of the extended bolts.

hey Shanawaz,
must warn you though that gypsy axles have a weakness with spacers on
the front axles just snaps,
have broken three axles already while testing my green spos gypsy,
lots of guys abroad swap toyota axles and get spacers on them,
regardig the fused wheels, for the flight of the hawkz, was runnning three spoke alloys as the fused ones were not tesed yet,
have put them on now, shall pm you results soon


regards,
Allan

Oh man, don't sacre me now.

But, I see lots of Gypsy/Samurai with -ve offset wheels. So what's the difference in having a 1" spacer or a 1"-ve offset wheel? Why should it break the axle with spacers and not with -ve offset wheels?

YES. I am looking forward to some news from you on this front. Been long time now.

Got them cheap -- that why I put them on.

Yes you get, but I got these at pretty reasonable prices so went for them.

Hi Shahnawaz,

The Spacers put additional weight on the axles.

If each Spacer weighs 1Kg then 1 X 4 X No. Wheel RPM (For Road Speed) = Additional Work.

Also in your spacer the wheel studs are too long, and they will carry all the load and bear the brunt of wheels jumping up and down (OTRs).

It is preferable to bolt the spacer to the original hub and then bolting the Wheels onto the spacer.

Regards,

Arka

Agree on additional weight part but shouldn't the alloy wheels be lighter than say steel wheels? So even if we have 1kg spacer put in, it should be lighter than steel wheel thus resulting in total weight on axle being less than before?

100% agree and an aspect of my setup I am not 100% satisfied about. This longer stud is a short term solution and I am in the process of going in rectifying it soon.

Yeah, I am one of the criminals that JDS has given a ticket to, hoping that I will 'reform' the society. So, that also means I will not be attending the night OTR

I feel the additional stress is due to cantilever effect (the load has moved further out), the reduced weight of alloys doesn't compensate for it. Anyway, let's listen to pros instead, I last studied structural mechanics 22 years back.

Samurai you are right, it is this extra leverage which creates stresses due to bending moments ultimately leading to shear (remember BM and SF diagrams?) This is also called as Offset swivel, i am attaching a pic for more clarity. Negative offset alloys will partially negate this effect, although not fully.

In simple words, the spacers provide the wheels with the leverage required to snap your axles

@Khan_sultan :This will probably happen sometime when you're "pushing it" on rocky terrain. Further, Spidey's ultra-low rock-crawling ratio and lockers will make it more likely. Any plans for a FFRA mod? Besides make chances of failure less likely, in case it does snap 1) It will be far safer & 2) You won't be stranded in the boonies, you can atleast be towed back.

@Spike : How will the effect be negated with the wheels being off-set Vs spacers? Will the forces exerted behave differently?

Best regards to all.

Addition of spacers make the offset positive, hence inorder to partially negate this effect negative offset wheels may be used.

In theory, possible. In reality - less possible.

When most people opt for alloys they generally upsize on many accounts - larger rim (more metal rim as opposed to rubber sidewall), wider rim (more metal again) and wider tyre (more rubber + radial belt weight).

Depending on the extent of the upsize, the end result could quite possibly be a heavier tyre + wheel combo!

That put aside, its the law of moments (leverage) that puts more stress on the suspension et al than the weight.

This reminds me of Chop Shop. Man those guys use such huge spacers. Scary stuff.

Its always best to maintian recomended wheel offset/position.
