I'm hoping to gather some opinions about wheel spacers.  The victim would be an 89 RRC.  I have thoughts about the pros of using spacers but are there cons I should be aware of from those of you who may have used them?  Should I be concerned about "strain" to the axels or braking issues?  I like the idea of a wider stance...even though in some unexpected circumstances she didn't even consider tipping.   Thanks for the input.  It feels like spring today and I have spring fever badly.

My biggest concern would be tires rubbing the body panels when articulating. Easy way to bend the panels and lopping off your lugs. After having had a wider stance in the past, and shearing my tires up, I am planning on tire that "tucks"* nicely in the fenders.

* Disclaimer: not the kind of "tucking" Dan is familiar with.

hmmmm....didn't think of that one.  I'll add it to the list.  Thank you!

and..."tucking nicely in the fenders"...is THAT what the kids are calling it these days?

In Dan's case it involves duct tape, spandex, heavy makeup, and loud house music.

Think "Flashdance" but with a husky voice and hairy legs.

I resemble that remark.

I've had both stock wheels, wheel spacers, and offset rims. The wheel spacers worked the best for my application (DII). The tires still fully tucked under all circumstances but offered a bit wider track. They never loosened up, and were easy to balance.

When I went to offset steel rims I had all sorts of trouble at first. My tires tucked if one side or the other articulated, but if I was fully loaded with water, fuel, etc and went over a water bar then both tires would barely hit the inside of the rear fender. I was able to trim the inside of the rear fender well w/o having to trim anything that is visible even with the wheel flares removed. IIRC the RRC doesn't have as much room in the rear fender well as the D2, so you may have trouble even with spacers.

Todd had spacers on his RRC, so his advice is probably the best here for your application. Todd -- how thick were your spacers? What rims were you running? What size tire? How bad was the rubbing/slicing?

The D2 hub design makes any additional strain from a rim with an additional offset moot. I'm not sure if that is true with the D1/RRC hub design though.

Those are great questions to follow up for Todd...thanks Craig.  Overall, the scorpian racing spacers give the RRC and extra 3 inches total.  Those are the spacers I've found so far.  I wasn't aware of the rear well issue, that's good info.   Todd??

FWIW, I had SR spacers and they worked well. I'd run them again if I wanted a wider track.

Never used spacers... I had slightly offset rims and wide tires.

On the RRC, I think it is a bad choice. But I am not the smartest guy here... Any other opinions?

FWIW, I run them on a Ford 8.8 axle under a Jeep Cherokee. Not being a Land Rover guy probably doesn't help you a lot but here's my experience.

The 8.8 is about 1.5" narrower than the stock Jeep rear axle and this is the most efficient way to bring the width back to normal. In my case it was done so I could keep the same backspacing on all 4 wheels and not have to worry about having two different wheel offsets.

Sine the Jeep front axle uses a unit bearing hub, there is always concern about additional leverage on the front end with a wheel with more backspacing. I didn't need spacers in the front but the wheels are 3/4" further out than stock and this hasn't hurt anything so far. I can't see how a spacer would be any different with a stock wheel versus no spacer and wheel with less backspacing. I would think that leverage is leverage.

One of the things that may be of concern is that many spacers, depending on thickness, will require that you cut the vehicle's lug studs down to flush so the wheel will fit onto the spacer. I used a 1" spacer on each side and that meant taking a ~1/2" off the studs. When and if you go back to stock you may have to replace these studs so you can have enough space to actually bolt on your wheel. I know that if I take my spacers off I will need to then pull the axle shafts and press in new studs of the correct length.

Make sure that whatever you get has grade 8 hardware or the metric equivalent. Mine are also hub centric and help ensure they are mounted as close to center as possible.

WOW John...thank you for the thorough response!  Although a slightly different use than mine, it's still a wealth of information.  I really appreciate the time you took.  It's all a lot to think about but at $500 for the SR spacers, that's a heckuva lot of money for an experiment!  I know that it would be ok up front but as Todd suggested, the rear wells might be the issue.  UGH!! "I used to be confused, but now I just don't know"! 

Thanks guys...

Forgive me for not knowing, but who is SR? Is there a website I can look at? I'm curious how they compare to mine.

The D2 hub design makes any additional strain from a rim with an additional offset moot. I'm not sure if that is true with the D1/RRC hub design though.

Craig

What about the D2 hub design makes this moot?  The farther away that the mass of the wheel/tire is away from the bearing will increase the strain on that bearing.

John,

It is cheaper to get aftermarket rims w/ less backspacing.

Determining if they will tuck is easy... you might even be able to use that laser level you got for Christmas.  Just measure how much room you have between the outside edge of the tire and the inside of the wheel well.  Don't count on the axle swinging up in an arch because that only happens when only 1 wheel is tucking at a time.  The wheel will go straight up if you, say, jump your truck (see the video section) or bottom out both wheels when going over a large obstacle like a water bar.

John,

SR is Scorpion Racing.  Their website is kinda fancy...and by fancy I mean hard to navigate.  Try using this link:  http://www.scorpionracing.co.uk/OFFROAD/htm/cats/whe/inner/pros.htm.  If that doesn't work, you'll have to go to their 4x4 section and then select wheels and tyres, then spacers.

Yowza....that's what you get for $500? I too would invest in new wheels. I'm guessing the spacers have a certain cachet coming all the way from the mother country to go along with the extra machining involved, but that's a fair spot of money.

If you are going to do it, get them from Adrian at 4x4ag.com.  He has them for $350 in their online store.

Thanks Craig...that's wierd...I had them bookmarked all along.    As for the laser level idea...I'll have to get a pitch fork and see if I can clear the crap off the bench and find it first but it's a great idea.  Thank you for that.

I had to add 1.5" spacers to the back of the troop to keep the tires from rubbing the frame at full stuff. I got lucky and didn't have to trim the lug studs. Also Isuzu's use the chevy bolt pattern so mine were only about 60 bucks off ebay. So far I've had no problems and it was like driving a new truck (handling wise) on the freeway. For 500 bucks though I'd just buy a new set of offset rims...
