That the ITR 5-lug pattern uses lugcentric wheels. Is this correct?

Does the front/rear hub look different then the typical Civic hub?

Lug centric - When the wheel is centered by the bolt holes/ lug nuts of the wheel, rather than by the center bore. Lug centric wheels should be balanced from the bolt holes.

Is that what you wanted?

So does the ITR have lug-centric wheels?

What does the hub look like? Will aftermarket hubcentric wheels work?

 

With the rotas SS's the hubs are bigger then stock wheels so they become lug centric, But to be honest... I have not installed a set of stock wheel in a long time so I can't recall 100% but I think they use the hub to center themselves.

 

Factory ITR wheels are HUBcentric. Even most aftermarket wheels come with hubcentric rings to accomodate a larger bore wheel to fit the ITR.

Typically, lug centric wheels are found on GM's

 

Lugcentric as in my old mr2 (or gsx) where the lug slides into the wheel?

 

Mike, thanks for clearing that up.

Anyone whos changed their wheels should know that one.

This is called a Shank design. Its odd, if you look at this design closely. You would think it is LUGcentric. However, even with the shank design, the wheel bore will match the hub diameter.

Mitsubishi and Toyota use this design frequently as well.

 

LOL. Yeah, if one of those was lug centric you'd never be able to get the wheel on!

In that thread I don't know where they got the impression that ITR rotors are lug centric though. You can lead a horse to water, but you can't teach it new tricks.

I don't think so (but someone can correct me if I'm wrong - hey, I admit that I'm not the most technical guy here ).

Lugcentric vs hubcentric depends on whether (a) the center bore of the wheel (that's the big hole in the very center of the wheel) fits onto the hub and that is used to center the wheel (that's hubcentric) or (b) there is no flange on the hub for the wheel to sit on, and only the lugs are used to center the wheel (that's lugcentric). As migs noted, the stock ITR wheels and hubs are HUBcentric.

Your question sounds like you're asking about lug NUTS vs lug BOLTS, which I'm pretty sure is a different question entirely. I'm sure you understand the difference between nuts and bolts. Some cars, like the ITR, have lug NUTS to fasten the wheel onto the car. The car has studs (another name for what are basically NUTS) which stick out from the hub. You slide the wheel over the studs and fasten it by screwing lug NUTS over the ends of the studs. Other cars, like most BMWs, have lug BOLTS to fasten the wheel onto the car. You slide the wheel over the hub and fasten it with lug BOLTS which screw into the hub. Both cars are HUBcentric, but one has lug NUTS and the other has lug BOLTS.

HTH

 

technically, usdm itr's can use lugcentric or hubcentric wheels - per the topic question. and technically, they do use both lugcentric and hubcentric designs in the same oem wheel.

however, we typically characterize the itr as having hubcentric wheels stock.

aftermarket, there are very few wheels that meet this criteria, so we use lugcentric instead (sometimes using hub rings as well).

Both the mr2 and gsx use nuts like the itr or any other Honda. The difference is a part of the nut goes into the wheel; I was curious if this had any centering properties. I know the difference between nuts and bolts; my POS 850 has bolts.

I don't understand what you mean by that...?

I'll try to dig up some pictures after I write a couple more papers.
