I've done it, and in 20k miles, I broke two studs. Not recommended.

They will slip on but not center up. So when you torque the nuts down, you are putting side force against the lugs. Done it, snapped lugs.

the "DEALERSHIP" installed the rims that are on my car right now, and they are 114.3
havent had a problem, yet

.7 may be enough slack I guess. But I have put some Pontiac rims on a Chevy (not sure of the size discrepancy)(some time ago. They seemed to fit just a little tight. Torqued then down and soon ping, ping. Started snapping lugs. I guess it'* a gamble you have to evaluate yourself. At the speeds I get to once in awhile, I like the safe side of things.

humm yea i can see that happening over time.. Thanks for the heads up!!!

Give it a little while. Its a gamble I wouldn't make again, ever. Simply put, its the wrong bolt pattern. Sure its only .35mm off per bolt, but that'* enough to put unnnecessary stress on your studs. You might not drive like I do, but I push my cars very hard, and its in circumstances like those that I don't want to take that chance. If you do drive as hard as I do, then you're taking a huge risk. Its like supercharging an stock L27. Just because it won't break in the first 10-20k miles, doesn't mean it won't break eventually.

I had the Audi A4 rims on my 95 Regal bored out professionally by a shop in California for $25 a wheel and had the 5x112 bolt pattern drilled out and the 5x115 pattern pressed in.

Yeah I see where you're coming from, I'm just shocked it was installed by the dealership themselves
I'm thinking 20s sometime soon so maybe I'll get the right bolt pattern

Anyone know the weight of the GXP wheel?

i think they are between 22 and 24LBS each

Hefty for an allloy wheel. LOL Am email to Ed Morad might get you an answer, Their pretty cool about just answering questions and I know they have shipped their share of them.
