Default How much off can the bolt pattern be?

Our 4th gen F-bodies have a 5x120.65 bolt pattern. I am really liking another set of wheels that are not quite the same bolt pattern. I know there are those who have been able to get by with being off by some.

The wheels I want have a 5x120 bolt pattern (so they are off .65). Will that work?

As far as those numbers go... i will say no they will not fit. and hollowing out hole for them to fit usually causes problems you dont wanna deal with if you can avoid. my 2 cents.

Just looked and saw 5x120 is the GTO lug pattern, so I know they'll fit.

Now it is debate-able if running that small difference is"safe" or "acceptable" or not.

Opinions?

NOTE:
When I am asking for opinions it is specifically for those that have first hand experience with this exact situation. I don't want random "educated theories" on what people think based upon no data they can back up.

yes 5x120 will fit. the .65 mm difference is so small when it is spaced out over the 5 holes. i have had my ruff 278s which are 5x120 on my car for the past 4 years with no issues at all. if you plan on doing high speed runs or tracking it all the time, i would say get a good set of wheels just for those times. other then that, no issues here

I'm on my second set of 5x120 wheels. HP Designs and my current Kyowa Evolve wheels. Yes, they are a tight fit. Some say to put a hub centric ring to have them properly centered, but I haven't had any problems on both the sets that I've put on my car.........

Thanks for the input fellas. I appreciate that you have read and per my request put in your opinion based upon your own experience.

What is it about high speed runs or the track that makes it more important to have the exact lug pattern? In my mind, once the wheels are on and the lug nuts torqed correctly, they wheel shouldn't move or have any dangers I can think of.

Anyone know?

i just wouldnt feel comfortable since they arent exactly a "perfect" fit. like ive said before, i never had an issue whatsoever but ive never taken it to the track or gone over 120 with them on.

Well, let me put it this way. The current wheels I have are discontinued Konig Monsoons. They are not the correct bolt pattern either (although I don't know how far off they really are). I have put 40,000+ miles on them, done countless runs at the track, and been 160+ in them 100+ times (yeah, I drive fast a lot and have for years). Not once have I ever had any problem what so ever.

But again, I am not sure what other than not being able to get the studs through the wheels the problem would be. I would love to hear from someone who knows exactly what the dangers are (if any), with some factual data or personal experience.

well if you already know your current wheels are not the exact pattern then there is no other pattern that they could be besides 5x120. so it looks like all the personal experience and facts that you are looking for......are from you your fine man.

ding ding ding. dude if your wheels on there now arent 5x120.65 then good chance they are 5x120. with that being said, youve done enough testing to get the facts.

Well tickle me pink!

I would feel better knowing exactly what bolt pattern I do have with my 17x9 Konig Monsoons. But they are an older wheel that has been discontinued for years, and I can't find out.

I sent an email to Konig. Hopefully they can tell me. Either way, I think I'll be alright. Thanks again for the input fellas.

No matter how small the amount is, you are still pinching the lugs toward the center off the wheels. Adding a side load that the lugs are not designed to handle. It seems lots off people do it with no issue, but there is the chance that something could happen.
