Personally, you are much better off getting the correct wheel.
I totally agree with you about getting the correct offset to negate the need for a spacer.

However, your feedback on the mechanics of a spacer is unsound.

That's like saying the same for a brake rotor, because it is an inert piece mechanically connected to neither the wheel, nor the hub; and just as a spacer it rests between the two.

You can run a +14mm offset and a 0mm offset on the rear with fender-rolling. i did.

auto fashion did one with 0mm front and rear.

But what wheel width / diameters?

Yes, but the hub actually serves as the support for the rotor, so it is necessary. It's contribution to thermal mass heat sink should not be ignored either. Spacers may inhibit this thermal transfer of heat to the wheel if the material is too thermally dissimilar and heat conductive grease is not used on the mating surfaces.

I'm assuming that you have evidence that this is a REAL problem (heat transfer) and that everyone should be concerned about-right? Otherwise, we have a thermal transfer problem in that your hot air is somehow being conducted through the internet.

That's a good one. Sounds good at least.

The thermal conduction thru lugs and hub mating surface [to the wheels] is very important to reducing the rotor temperature and making sure the wheel bearings don't get too hot.

Ever see cheap plastic hub ring adapters?

Quit confusing them with reality, Dennis. It's all about the fantasy! Physics is not for the fashionistas!! Better to look kewel than to work well.

You would think at least one person would have mounted a CPU once in his life!?

Oh well.

I've seen "cheap" plastic hub ring's hundreds of times, used them myself several. Never has one melted. You guys are weaksauce, sorry. Go back to your stock cars and drive them happily and ignorantly while some of us are hot-rodders and always will be.

Its the young versus the old! Most innovation comes from the rebellious and those that have problems with authority. This happens to correlate with youth very well.

Maxnix-I've noticed that you never answer when someone calls you on your BS. Why is that?

To stoke the fire further-is heat transfer important in a wheel/hub/rotor? Yes. Do you have evidence (actual not theoretical) that all metal wheels spacers decrease heat transfer to the point that parts are actually damaged? Furthermore does the damage (if proven) require action from the owner. What if someone wants to trade 10,000 miles of wheel bearing life for performance/aesthetics?

as far as the hubcentric rings go, you dont really need them... the hub center doesnt actually carry any load, its the studs that carry the load (which is then transferred to the hub assy)... the hubcentric rings basicall ymake sure the wheel is centered on the hub, and thus centered on the studs so when you put the lugs on it will be straight.

If you semi-tighten the wheel lugs before you put it on the ground, it will be fine, then final torque when you put it down....

Ideally, you would like a hubcentric wheel already. Theres no doubt....

The same thing goes with spacers... Yes, your car may not mess up by using them, but what is better, a properly offsetted wheel, or a wheel with a spacer? The choice is OBVIOUS... We've already had the spacer debate, and we will not go back into that....

Some choose a wheel and tire combo for looks, and thats all fine and good... Others chose it for performance........ the rest of us choose something in the middle.... One must be aware of the tradeoffs associated with the combinations....

I have to say I pretty much agree with all that.

I also agree but I like how you say it- facts with no editorializing.

Now if you'll excuse me I'm going to make some wheel spacers out of some scrap plywood that's rotting in my backyard. I'll report back with an article.

One thing we have to "keep in mind", is that we aren't the only ones reading these threads/boards. There are alot of browsers that read through posts on NICO and take them as "gospel". If the good and bad of thigns are not mentioned at the same time and with similar "weight/emphasis" the casual browser may take it as being the best, without considering the trader offs.

It would be nice if everyone considered the other point of view and perspective, versus blanketly disagreeing.
