I wish I was a moderator as I would nuke this thread.
I would have to agree on this one... but i also have to admit i have only a 'hunch' to go on. A hunch is not enough for me.
I have been to a good handful ov serious wheel/tire/chassis guys and brought this up. Mustang 17 & 18" rims are cheap and plentiful... and not everyone can afford real rims. Spacers come up a LOT in casual conversation. Every single one ov these guys uses, has used or even recommends these things (bolt-on billet hub-centric spacers). The rock-crawler and 44" mudder testimonies are always brought up, and to everyones satisfaction, but it still doesn't sit well somehow, with me. If a truck hub fails its not usually at 100+mph, and any abuse those monster rigs see is always off-road. Cars WILL get flogged on public roads, mine will see a lot ov canyon fun... so the hub-spacers scare me a bit.
Still... for $200 i can mount ANY cheap wheel i can find, with a perfect offset. Mighty tempting. The above poster (not Tom) mentioning no Google-search mentions ov failures is interesting though... certainly something would have come up, and you know it would be mentioned online.
Hmmm...

I can definitely see their limitation, especially if you're coming at it from someone like Tom, who's on a track going 150+ MPH.
BUT a good quality billet adapter isn't something that is going to fail. I'd trust a good quality billet adapter allowing the use of good quality wheels (i.e. my OEM mustang rims cast here in the USA) than any of the offshore cast wheels that our out there that may have the proper offset.
for typical driving, and even autocross, I've never seen a failure of good quality, bolt on adapters. if there was a failure, I'd bet money it was due to, as previously mentioned, the adapters not properly torqued and the lugs backed off. of course, that can happen with an aluminum wheel even without an adapter, too.

I don't see the problem as a lot of drifters use spacers on their cars pushing upwards of 300-600 hp and the whole sport relies on you going sideways through corners and I have yet to see one fail...

Do a search on Ruf Porsche 930... Might even add 21mm (3/4") to your search... If Ruf finds them acceptable for a car like the 930..... I think most folks on Moparts aren't gonna have an issue...

Im gonna run some 1/4" spacers this summer in the front. Already have Mustang wheels and they are lug centric on my Dodge anyway so guess what, a spacer isnt gonna change squat.....
Mopar to the bone!!!

I've run 1" and 1.25" spacers on my car. I've never used the "shim" slip on type, only the solid 6061 with high quality studs. that bolt onto the hub type (and then you mount your rim on the spacer) I've never had a problem with them. On the street, never an issue. Unbolt the street tires, put on my Autocross DOTs, drive to the event, drive the car hard for about a minute at a time, average day 6 runs, and drive home. Change back to street tires. Every time the rims are off I will check the torque on the spacers with my calibrated torque wrench (because I'm paranoid). Suffice to say, I've never had to re-torque them, everything stays put at 100ft/lbs. Now for the sake of argument, I broke out my old statics and dynamics books and drew the free body diagrams for both a 0 offset wheel and 1" offset wheel with a 1" spacer. Using the normal FBD as the given, I compared it to the offset FBD. At the wheel hub, there is a different torque moment. However, the spacer transfers the forces of the 1" offset wheel into the hub like a normal 0 offset wheel. This is much like Feets custom wheels he had made with the extra 1.25" boss forged onto the back of the hub. However that's in static, and assuming the wheel will not see forces that will flex it. Dynamics could play a role on the outer wheel bearings as there's an additional torque from the longer lever arm now attached to the hub. AndyF, care to check that? I think I'm right. I'm even going to double check with my old prof on Tuesday. And the only reason why I currently use spacers is that I don't have the coin for nice forged 17x9s. Genuine Ford rims are the best choice for me now, it just does get annoying with 40 lug nuts rather than 20.
