I need your help Wise Rim God's!!!
Will BMW rims with a bolt pattern 5X120 with a Center Bore of 72.6 MM fit my 1998 SS? The fronts are 19X8.5 with a 1.5" lip & the rears are 19X9.5 with a 2.5" lip. They say the offset is 38. I have old school 18X9.5 ZO6's right now and I want a new look. I don't want to spend the cash on some rims that are not going to fit right and end off flying off the car when I'm on the highway. I read something in the past about BMW rims, but I tried the search and nothing. Any of your info would be great. Thank you for reading this and LS1Tech.com

more power to the people that run a 5x120 bolt pattern, I guess I don't like taking chances with stuff like that. I would also think w/o hubcentric rings that you would increase your chances of having a vibration due to the improper bolt pattern. As soon as you would tighten one of the lugs you would introduce 0.33mm of runout. This would also leave the lug 180 out to not seat properly by 0.65mm and cause uneeded lateral stress on the studs.

So far, nobody who's owned them has reported experiencing the catastrophic scenario of one of their wheels flying off while going down the highway that some people like to claim is destined to happen.
Don't believe the hype. Get some hubcentric rings and you'll be fine.
Your wheels and tires are the ONLY 4 things keeping your car shiney side up.

Seems like with as many lawsuit happy people roaming around these days, selling this pattern of wheel to F-body owners with that much "liability" would have put alot of people out of business don'tcha think?

I would venture to say that with only 1/100th of an inch worth of "pressure" being applied to the outermost edge of each bolt hole, the brunt of this is probably softened by the threads inside of each hole collapsing. (Thread depth at 1/100th of an inch seems about right.) Something else to keep in mind is that even though there is .65mm less tolerance to work with in fitment, a 120mm spaced wheel will still slip on and off a 120.65mm hub without force being required. This is the most important aspect to consider because it indicates that there is very little if any preload introduced to the wheel studs. If hubcentric rings were not used then this would be a different scenario since the "lopsided" movement of the wheel would increase lateral g's, (probably exponentially), on 4 of the studs. So, hubcentric rings are key in making that bolt pattern work.

I want to thank everyone and keep the info coming. Post pictures of your set up your running on your car and maybe on the rings too. I hope I'm not the only person going through this right now.

Personally I have used the 5x120 pattern, and I will use it again. The reason that the 5x120 pattern is used so often is because of this. The only reasonable priced wheels in the 120.65 pattern are wayyyy played out (C5, Z06, ZR1, etc.) Unless you have a small fortune to spend on wheels in hopes of being different (iforged, Fikse, HRE, CCW, etc) You are almost forced to go with the 120 pattern. And the average car guy is not going to spend $3K+ on a set of wheels. Its just out of our budget, plain and simple.

People are not wheels however. If you could somehow come up with a way to decipher the physiological differences and how each were impacted by alchohol to be found in any random sampling of humans, you'd then have to contend with the infinitely random conditions/circumstances that any person could be confronted with during any driving session. If by some miracle you were able to quantify all of those variables and apply the scientific method to them, you would then be left with accounting for the human mind and how it would interact with/be affected by any of the other variables in the whole experiment. (I'm sure I'm still leaving alot out of the equation, but you get the idea.) The bottom line is, in order to come up with any useful data that would actually prove anything, you'd have to figure out a way to control a random sampling of humans' reality, which unless you're God is kind've hard to do.

I haven't performed any comparison tests between the two, but common sense would dictate that polycarbon is going to absorb vibration/shock a little better than aluminum.

Running Evos here with those same specifications you just posted. No problems whatsoever. I'm running hubcentrics rings also. No vibrations. Of course for the love of God use common sense and check your wheel lugs from time to time!

Yea, Slayer is right. I'm selling my CBR600RR just so I can afford the wheels of my dreams. God only knows how much I love my car. Somebody pinch me, did I just say I'm selling my motorcycle for a set of wheels. Man I'm loosin' my mind.

is there really not anything between 1k and 3k for the F-bodies?
it just seems like there should be some options for wheels in the 4 to 5 hundred a wheel category, as well as some in the 3 hundreds or 6 hundreds
