yeah I'd rather just run a different offset

 

Theoretically, the rim strength is probably not the issue, the usual concern is stud strength or hub strength. To put the least amount of stress of the hub (so the moment arm is statically zero with no movement or camber) you would want the hub/ wheel face to be lined up with the center of the wheel (as in 4.5in from each edge on a 9" rim, which I believe would be a +0 offset). Now that would all go out the window as soon as the situation is dynamic and camber is added... Its reasonably confusing and I am not 100% sure on what I just posted though I know anything with a '+' offset is going to be closer to the outside edge and '-' is closer to the inside. In a static situation a +38 and a -38 would put the same stress on the hub in opposites directions. The bottom line is that so long as you have a well made spacer and good lugs and studs, there is no issue with running a spacer.

 

QUESTION:

So if I bought some 17x9.5 +12 wheels ...(someone told me after I paid they dont fit the evo)

What spacers would I need to make them work...on a voltex widebody

Someone please help

I posted questions all over this forum on the +12...but no luck

thanks

 

the spacer can make it only wider . +12 off set is insanely aggressive with your sizes.
You can ex change them something like 20-25?
around that you still will be very very aggressive wheel set up. I dont know , what is the wheel fitments for the Voltex bod kit. If its really aggressive, maybe your +12 off set even can fit , i guess.

Here is some info about how the off set works:







i hope it helps.

Ideally, you should get wheels with the perfect offset rather than relying on spacers.

If you do run spacers, keep them to a mininum, I'd say 10mm at the most.

 

I have no clue where the irrational fear of spacers comes from... but it has been prevalent as long as I have been tracking my car. Most often, the ones recommending that you not run spacers are the ones who have never run them themselves.

Ive run 5mm non-hubcentric spacers and 15mm hubcentric spacers on the front of my car. Have had the 15mms on for the past 2 seasons. Never had issues with either, but I would encourage going with hubcentric spacers if at all possible. There are companies that will make custom hubcentric spacers of smaller sizes (ie: 5mm, 7mm, etc) as the standard Eibach and H&R 5mms are not.

Pay them the same heed you would any other critical part on your car. Don't cheap out on materials/brands/etc... and you will be fine.

 

then you cant rotate your wheels during track days to even out tread wear etc...

 

If pro racing teams, and the HKS Evo run spacers... I am sure it is not all that bad of an idea.

 

I've been running spacers on my car... from 10mm to 30mm.
not one problem thus far.
I just check before each event to make sure they are torqued down.

 

I having been running 25mm spacers for 2 season. I run 18x9.5 + 40 NT03's with 275's.

 

Spacer will be find if you do it right and not use low quality one... or you will end up like that stupid guy in his RX7

Custom made for my R33, they don't move at all! and still have lot of thread to torque.

 

Thx for all the feedback on the spacers issue.

Along with spacers usually come extended well studs. I'm seeing that ARP extended studs seem to be the norm?
With my new setup (info below) I'm seeing the need for some extended studs. I wasn't aware that just plain 'ol CE28's had this thick of a backspace or whatever it's called. I'm only seeing 9 thread revolutions vs the stock 12.5 revolutions and I'm not sure that's all that safe for the track.




As an update for this thread.....
My main goal was to try and find a 9.5" or 10" non-staggered offset that would not need spacers. I think I found that in 18x9.5" +28 CE28's. See pics HERE. But all is not perfect, as even with rolled rear fenders a +28 will occasionally rub in the back with a 275 tire. I could buldge up the lip or go wide fenders but not really liking those options yet.

So, assuming there's room on the inside for a higher offset - I've measured and there is - my next set of rims will have a slightly higher offset in the +32 to +35 range depending on brand. This offset, however, might require a small 5-6mm front spacer. So we're back!

 

Of course it's always better to not run spacers if possible. But unless you can afford to buy wheels for every offset/track change, spacers are the easy, affordable, way to achieve these changes. Have to use proper studs, nuts, and proper installation methods for all hardware. Checking fastener integrity regularly is also highly recommended.

 

who makes a good quality wheel spacer? something small, like 3mm or 5mm

 

You sure like referencing mis-information huh?

That video did not have spacers, he had wrong size lugnuts. Nothing to do with spacers.



I have been running spacers on 4 different cars over the last 5 years. Make sure they fit properly and you have enough wheel stud and you will have no issues. Spacers put no more stress on the hubs then larger wheels do. When is the last time you heard Evo owners complain about hubs going out?


When you torque a spacer between the wheel and hub, it transfers the stress onto the hub. I have never had a wheel stud break because of spacers, and I have never had a wheel come loose because of spacers.


If your really nervous, get the hub centric ones:
