how much weight is acceptable to add to a rim to balance it?

i am looking to get a set of m6 rims for my 335 and i have heard stories about some of the replica rims, csl, miro etc, needing 4 to 5 ounces of weight per rim to balance

when this is done you will almost 100% have vibration that will never go away. plus the fact that you have all these additional weights that can pop off, which i have seen happen over bumps

how are the m6 rims from either **********s or jlevi?

do both these companies sell the same m6 rims, or are they from different manufactures? should i go with one or the other?

i would ask both these companies but there both going to say there rims are better and to buy from them anyways

i just dont want to order these rims and have to add toms of weights or have noticable vibration

i know there replicas, but there still going to cost me $800 .

Weights are added to balance the wheel tire combination because it is very rare that any wheel/tire combination is balanced for its entire mass.

Not really a dumb question as it is a fact of life. I don't think there is a set answer as there are so many variables between the wheels construction as well as the tire's.

Keep in mind that balancing your wheel also has to do with the brand of tire you're putting on and also the method by which it is balanced. I prefer the Hunter GSP9700 system for getting my wheels setup http://www.gsp9700.com/

It looks like the best solution for you is to get tires/wheels (mounted & balanced) at the same time from the vendor. This way, you're assured that there won't be any balance/vibration when the wheels are put on the car.
