I really haven't found any wheels that I like for our 5x120 setup. Anyone have a site or two with a good selection. The only sight that had any selection was tires.com. I really didn't like any of them. I am looking for 18x8 and 18x9.
Brad. Arrowhead Performance had a "group purchase" deal going on the Intro Exposed Series wheels. I do not know if that deal is still going on. Here is a link to the Intro site... Intro Custom Wheels
and here is a pic of the Sport GT wheels I have on order...

18" Intro GT Sport Wheels, Toyo Proxes T1-S Tires.
Carbon Fiber race hood off Stu Hayner's #5.
I have these coming from Todd at Discount Tire. 18x9 in the back with 18.8 up front. All brushed aluminum finish. Getting 275 and 245 18" tires, Dunlop Sport SP9000 hopefully or Falken FK451 should the Dunlops not be available.
Those GT Sports look pretty cool. Are they lighter than stock? I would definately want that aspect of the deal. If they are going to be larger their mass better be less.

Those rims look nice for the mutli-spoke look. They look light.
Thanks. I'm just sort of burnt on 5 spokes. I think I've had 5 spoke rims of one style or another on every car I've owned in the last 10 years. My first thought on the GTO factory wheels were that they were beautiful but ugh, here we go again. I just looked for basically any wheel that wasn't 5 spoke in design. It's just me though.
you can check out www.bigwheels.net, but be carefull cause some of what they say will fit won't, you have to check the numbers. I like the wheels I have but I did have to roll the fender slightly. (they provided the tool to do it at no charge.)

There are not many selections yet for the GTO. In fact, i doubt there will be very many ever. This is due to the unique fitment for this vehicle. the best place to find wheels is this sight. Hopefully, I will have a really nice set of "OZ" wheels for all of you to see. Will be 18 inch with 8" and 9" for the rears. Came in today, and am mounting some Falken 451's We have installed these tires on some Trans AMs and performed quite well. OZ wheels are some of the highest quality stuff out there, and very light. had to get the wheel in a blank and have OZ adjust the offests. Are different than any of the wheels on the sight so far.
guys make sure when you get after market rims that they centre bore locate that is when you the get the rim without tyre fitted place rim on car the cetre hub must be a tight fit. if you can move the rim up and down on the hub to much you will need to have locating rings in the centre hub of the wheel.if to much room on centre hub without locating rings the car will vibrate at high speeds and everone will blame the tyres where the problem lies with the rim any good performance tyre outlet should be aware of this problem. not dangerous just annoying
I'd like some HSV wheels be honest, alot of holden service departments sell em for a good price once the new look everbody wants em has worn off. I think alot of thoes OZ wheels etc are kinda ricy.
also a HSV "I just want one" sticker in the back window:-p nobody would understand it though
What is everybody doing about the centerbore issue?
The strange 69.5 mm centerbore is the reason some retailers do not list wheels for the GTO. Some (like Aussie Bill) say that you should only use wheels that match bolt pattern and centerbore. Other sellers are not as conservative. One thing is sure, if you use non hub-centric wheels, do not put any weight on the wheels unless the lugs are fully tight to the mounting flange.
Most of the wheels being sold for the GTO are not hub-centric. I have not been able to find out if the ROH wheels are, but coming from OZ they may be.
I think that I am going to mount a set of OZ (the wheel manuf.) wheels that are not hub-centric, but I wish I could get a set that had a centerbore that fit to the hub.

as you can imagine in aus most aftermarket wheel manafactures cater to the two most popular cars which is holden and ford so most of the wheels you buy the centre bore will be right.there is a lot of wheels that have bigger centre bores but most manafactures will put a set of hub locating rings in the box to fit. locating rings are usually made of plastic or alluminium and fit in the hub of the wheel making the rim a snug fit. if the rims you buy are to big in the centre bore and they haven't issued you with hubrings you should be able to get them from a good tyre and rim seller where i used to work we had them by the thousand in different sizes it was just a matter of finding the right set. if all else fails make your own out of alluminium.If the centre bore is to small any good machine shop can bore out the cetre of a rim to any size that you require thereby negating the use of hubrings. Also i will stress again only use wheels that have a 5/120 pattern
I got the plastic rings with my wheels, not sure how much good they actually do but I did put them on.
beleive it or not without those rings the car could vibrate at high speeds. when i was in the industry not all that long ago you would not beleive how many customers would come in complaining of vibration first think we would notice is if they were wheels we fitted, if not our wheels 80% problem fixed by set of hubrings. glad you fitted the rings you did the right thing.

I have noticed that my car vibrates for the first mile or so when I start driving after it has sat for about 4 hours or more. I don't know if it is related or not, I think it did it with the stock wheels too though. After the first mile it smooths right out. Somebody told me it has to do with high performance tires and it should be less noticable when the weather warms up.

what size tyres are they iam assuming that they are 18's and very low profile which could indicate that when the car sits overnight it takes awhile for the tyre to warm up to get rid of the flatspot this happens a bit in very cold climates
The +48mm offset and the 5x120mm bolt pattern are, by now, pretty much common knowledge. The 69.5mm center bore, however, is news to me. The fitment of the wheels I have on order was tested and verified by Arrowhead Performance, so I have faith that they will work the first time. I will be SURE, however, to mention all this good info to the crew installing my wheels. Thanks for the "heads up".
Florit, Do you know if the wheels that Arrowhead is installing are
Hub-centric? I have received so much info Pro/Con to this issue that I am holding off on installing wheels until I can get comfortable with this.
I sent Howie an E-Mail some time ago asking about the status of the ROH wheels that he is selling. And have not gotten a reply, so I do not know what their philosophy is on the Hub-Centric issue.
Why has centerbore of the wheels become an issue just now and on the GTO? I've owned many cars and have put different wheels on all of them and this is the first time I've heard of such an issue. Why now? what's different? I ordered a set of 18" billet wheels through Discount Tires from Coddington. These were custom made for me and have taken a month to make so far. Am I going to need these centering rings? I just don't understand why I've never ran into this problem before. I do not have my wheels yet so I can't tell if they will be tight or loose but I will check before I have the tires mounted.
I would suggest to Pontiac that that future GTO's wheel bolt patterns be changed to 5x4.75in. instead of this bs 5x120mm. It really limits wheel choice.

You should be OK with the Coddington wheels, since they are custom made they should be able to make them hub-centric.
This is first car that I have heard the centerbore issue also.
Previously, I think the centerbores were more standardized. The GTO has a different combination (wheel size, bolt pattern, offset, centerbore) so not any wheel will fit. Wheel fitments for BMW 3 series will work in most cases, other than the centerbore.
I am not aware of an American manufactured car with 120 x 5 bolt pattern either.
I would love to hear an educated explanation of the risks associated with installing non hub-centric wheels.
TireRack is very conservative about it. They will only guarantee
hub-centric fitments. That is why they do not yet list any wheels for the GTO.

I hope they don't change the wheels since I have new wheels on my car and I would like to use them on a 2006 GTO.

i will cover this issue the best way i can. nearly all modern cars nowdays run centre bore located rims even steel wheels are centre bore located. centre bore located means. when you put the wheel on the car it is centrally located and when you tighten the nuts the wheel is perfecetly located on the hub.aftermarket wheels sometimes the centrebore is larger eg GTOcentre bore 69.5 so if you put a wheel on the car and the centre bore is to big , when you tighten up the wheels means the rim is not located centrally on the hub which can cause high speed vibration 60mph usually not dangerous just annoying.to overcome this problem manafactures use hubrings to overcome this problem. all the hubrings do is take up the slack between the rim and the hub. you can still fit aftermarket wheels with bigger centre bore on car but chances of vibration increases this is not dangerous just annoying. america is like us in that aftermarket wheel manafactures cater to the most popular cars in aus rear wheel drive usa fwd that is why aftermarket wheels are hard to get fwd usually run neg offset rwd pos offset

Ours wheels are hub centric. We do have a proven fit for running 18x9" wheels wrapped in 275/35/18 tires on the back. Having driven our GTO with the 18" up to 130mph at the Bondurant school last week I can assure you we had no vibrations! BTW if you ever get the chance to take some hot laps with Bob himself I highly recommend it! What a thrill riding shotgun as he pushed our Goat to it's limits!!!
I never got you email, shoot me a call with any questions you may have!!
