What am I talking about? I dunno, perhaps a sit in any statics course will help clarify things for you. The adapters put on excess stress on the hub/bearing assembly. Not to mention there is about 1-2 mm of material between your 5 bolt pattern and your 4-bolt pattern in some areas. This creates another area of high stress.

You obviously don't know anything about this, you just run them because they're a cheap alternative to a proper 5-lug swap.

I made my attempt to show you the idea, but this is the internet and I don't expect you to really take head to my advice because people on the internet already know everything... I don't know why I'm wasting all of this money graduating from an engineering school then. :roll:

im following.....And i believe these are aircraft grade aluminum? which is strong but prone to shearing

[Zacm829]

get em'

True... and the focus of all the forces from the vehicle to the ground, through the wheels, is on that stepped lip which is in shear.

These adapters have unsafe written all over them but the internet says they're safe so I say we start a group buy on them!

Bump for the OP to sell the wheels... hope the buyer has a 944 to put them on.

[lowlightbw]

what would be the answer if the OP hasn't had any problems and his wheel bearings are fine? 20,000 miles of luck? im sure there is some level of risk, just wondering if the level of risk is that great in comparison to the amount of stress that is being applied.

alright, awesome, i respect that you are going to learn shit. why the hell do you have to come into this thread and shit everywhere.

I have not broken anything, i dont care what people think, i dont drive like an idiot, need i say more?

YOU are the reason i hate being in an e30.

ill wave as i pass North Carolina on my 10 hour drive to maryland tomorrow, just for you

[GaryE30]

I'm the reason why you hate being in an e30 huh? Do you think it could be because you cheap out on things like the typical e30 driver? Basic fact... e30s are cheap to obtain, but not cheap to modify correctly.

Also, I wouldn't consider calling it bashing when peoples well-beings are on the line. Granted you're not selling them the adapters. My comments were solely about the adapters and their safety. Congratulations for selling your wheels though. For someone to call them safe is just beyond me especially when that person little knowledge of the product.

You don't care what people think? That's pretty naive/juvenile of you to say when you put others at risk. One thing... if you only take one part of my advice from all that I've said, let it be this... GROW UP!

I'm sorry your panties are in a knot. Let me make it up to you and take you out to lunch when you pass through. :up:

Haha "cheap out." There is a lot more thought and expense put into E30 trash's setup than just buying stuff that's already available and slapping it on. And it shows, because his car looks a hell of a lot better than yours.

Maybe yours does perform better, but I'm not on the internet to drive cars. I'm on the internet to look at them. Enjoy your engineering while everyone else looks at your car thinking that it sits like it has sagging springs out back.

[z31maniac]

Except that they put twice the torque on the hub/bearing...

You may get away with doing this for a while, but you're killing your bearings. A basic equation from any general engineering course, Torque = Force*Distance, will show that these adapters put extra stress on the bearings.

Now as far as safety goes... who knows what could happen if the bearing suddenly seized or the studs holding the adapter on breaks because they're under a ridiculous amount of force.

Then this would go for spacers as well correct?

At what thickness do they become unsafe in your opinion?

Wow, spacers arent the same thing. The bolts actually Pinch the spacer. Making it a hell of a lot safer and obviously reliable.

The adapter bolts on with 4 bolts and then the wheel is bolted on with 5 bolts on a larger pattern. So ALL of the stress in on those 4 bolts plus the leverage of it sticking out 6 inches. You have to remember that BMW nearly centered the wheel over the brakes....

All Gary was stating was the fact that they arent "safe" and they shouldnt be endorced as such. will they work? Obviously.
Do they create alot more stress on a already failure prone bearing?(on lowered E30s)Absolutely.
Is it a free country and he can do what the fuck he wants? well.....YES

[kronus]

^^ right about spacers.

hurf durf internet

Seriously? You can't possibly not be trying to start shit.

A lot more thought huh? Okay, let's see, he just combined different adapters and spacers... man the thought involved! So what you're saying is if I completely redesigned the e30's suspension and came up with something totally different but used shitty/unsafe products that it would be perfectly okay and safe because it involved more thought. I love your mindset. As far as expense goes... I don't think you know what you're talking about.

His car looking better than mine is your opinion. I never dissed the look of his car, as a matter of fact I do love the look of his car so I don't know where you're trying to go with that statement.

I'm sorry if you're not a fan of how my car "looks" on the internet. If you're here to buy an e30 and just take pictures of it to post on the internet then thats okay. I don't really care. Some people choose function over form, some people choose form over function. I'm a fan of both when done properly.

Basically everything you have said here is your opinion and has no relevance to the issue.

Good day!

My thoughts exactly.

[E30trash]

can someone lock this thread already, the wheels didnt even go to another e30 owner.

plus gary is over here shuttin shit down.

i wanna keep these adapters on this car forever. i want to break all my wheel bearings.

[expressfish]

thus the molecular bonding of two dis-similar metals creates......bla blabl bla bla bla. geezz. It is a hot thread tho :)
