Would these fit?

I'm looking at getting some rims and I need to know if these would fit a stock GTP without needing to change or modify anything:

Rim Diameter: 18"
Rim Width: 7.5
Bolt Pattern: 5x115 or 5x112 (I'm pretty sure 5x115 will fit my car)
Offset: 42


Then I was planning on getting 245/45/18 100W tires.


Thanks for the help.

It should work providing you use only 5X115mm or 5X114.3mm but many aftermarket wheels have multiple bolt patterns. Wheel offset looks about right too.

Tire size is good too. Good luck!

Thanks for the reply Bob. I really like these.

Question: Why would a 5x115 OR 5x114.3 work? Is it just such a small difference between the two that the studs are still able to make it in the lug holes, they just aren't perfectly centered with a 5x114.3? I was surprised at how few 5x115 rims there are out there compared to some of the other sizes.

I attached a pic of the ones I'm thinking of getting. I know you aren't a fan of the multiple lug holes, but it doesn't really bother me. I think these would compliment the car quite well because they are 5-spoked like the factory rims.

Have you looked at the Eagle Alloy 077's? A set of 18" chrome EA 077's would look sick.

:eek7:......THESE would look sick, Tim. THESE ones.

Those are nice though. Couldn't find any for sale anywhere. And if they are cheaper than the ones I am getting I am going to be pissed. :angryfire I wasn't totally at ease with getting rims right now, but Tiffany really wanted them so what do you do? :rolleyes: Keep the lady happy, that's what! :iceslolan I did want them as well, but probably would've guilted myself out of it because it's not a "need."

Not that I don't like universal fit wheels but there is an issue with getting the right lug nuts and then the right tools to remove the lug nuts in case of a tire issue like a flat. Standard tire lug wrenches may not fit or work.

The 5X114.3 bolt pattern is the Ford Mustang bolt pattern which there is a better availability of. I know GP owners that use that pattern/size and it fits believe it or not. :dunno:

Yeah, the seller says tuner lugs are required for those rims. That's fine with me since I have tuners on right now.

Well the rims came today and they look great, BUT they sent me 17's! :sly: I called the rim place up and found out they don't even have the ones I ordered and won't for another month! To try and make it right, they said I can have my pick of pretty much any other rims they had - even more expensive ones. The downside is that they don't have a huge selection and two, they don't have any more that are 5x115's.
I know that 5x114.3's will technically fit, but I believe this will put added stress on the wheel studs and possibly the hub/bearing. The rim place said they would send me free hub centric balancers (or something like that) for free, but I have no clue what those are.

So what do you guys think? Safety and unnecessary wear are my main concerns here. Should I stick with 5x115's or is the diff between the two so microscopic that it really won't make much of or any difference with the 5x114.3's?

I know of people running 114.3's for a while with no issues. Keep in mind 114.3 is only .7MM away from 115, less than 1mm off, so that is why they fit.

If I were you, I would be sort of ticked that they sent 17's. I'd probably hold off for them to get you the ones you want. Plus give you a discount for effing up the order without even so much as a phone call.

That's actually exactly what I'm thinking of doing. None of their other ones really grab me. It just sucks that I'll have to wait another month. I'll call them and see what they say.

Good plan.

Ha! So I told this seller that I wanted a refund and that I'd consider repurchasing their rims once they actually had them to sell (because they were the cheapest I could find.......UNTIL TODAY! HA!) So they refunded me and I found another place to buy them from and it saved me $90! Finally a stroke of good luck with this stupid car! lol

Just picked up the car with the new wheels. :)

Yeah they look great. I've always been partial to factory rims though (too many bad stories about aftermarket rims bending) but the factory GTP rims look boring so I switched mine to 2007 Pontiac G6 GTP rims (currently looking for a place to powder coat them, the grey just isn't doing it for me)


How much did your tires cost? What tire manufacturer/model? Are they noisy? That's the biggest consideration I make when upgrading. I almost purchased 19s until I looked at the cost of tires and how hard they are to find.

Where did you get the bumper?

Thanks! I like the factory polished rims too, but if they were only 18's...:rolleyes:

I got Falken Ziex 245/45/18 tires mounted, stemmed, balanced, warrantied, rotates, balances and an alignment for just under $600. I did a lot of shopping and that was the best deal I could find. You're right though, going from 16" tires to 18" is pricey compared. The drive home wasn't noisy at all and I couldn't tell a difference in driving really. I made sure to get 5x115 bolt on the wheels because I didn't want to take the risk with 5x114.3's.
Yeah, 19's are a joke. Extremely rare and therefore extremely expensive :headshake. It was actually pretty tough to find 18" 5x115's as well.

The bumper I did myself to the stock bumper. :biggrin:

Yeah the 18s I have on right now are pretty quiet and handle wonderfully, but then again its my first pair of asian tires (yokohama). I will never go back to american. I tried Falken before and they were great, but my front tires were BFGoodrich that were pretty noisy.

Have you had any problems cornering up/down a slope and rubbing the wheel well? I had to modify my wheel wells, and with my springs sagging from age I'm starting to cut it close again.

Any chance you have a write up on the bumper mod? I'm pretty much finished modding the engine and looking for any good exterior mods.

No rubbing issues noticed yet, but I've only had these on since this morning so we'll see. Hopefully not.

No, I didn't do a write-up on the bumper mod, mostly because there was no plan at all, I just kinda made it up as I went with a lot of help from my auto-body talented mad scientist brother. To be honest, I wouldn't recommend doing what I did because the fiberglass, bondo, and bumper plastic don't flex/expand in unison with temperature changes so slight cracking is starting to come out. If I ever get to it, the best thing to do would be to make a mold of this bumper and then fab an entirely fiberglass bumper which I would really like to do some day. I also want to make a matching front bumper too like the one they have on pfyc. I've never seen a modded GTP rear bumper so I thought it'd be a neat, unique thing to try. To get the scoop to fit though I had to cut out a square from the sheet metal behind the bumper. Not a big deal at all, but you need a decent disc cutter to do it.

Here's some more bumper shots (I don't know why I left the trunk popped for the pic. lol.):

I went to the junk yard and got some honeycomb grill mesh from a Pontiac minivan and cut it to fit in the scoop holes. It turned out pretty good. You can barely see it in this pic:
