I have them on 3 wheels on my R107, but I am replacing them as I find shorter bolts to use. In my mind, the infinitessimal difference in the appearance of the wheel is not nearly so important as the inconvenience and expense of having a flat out in the boonies and having to have the car towed and then ripping the wheel apart.

I have not had this happen on my R107, but I have broken a couple of these puppies at junkyards.

I don't think it will happen to me, but why risk it? I notice the shanks of these things flexing as I torque them, and they are not on as tightly as I really would like either. The downside risk is too great vs. the reward. I got enough problems....
