Coming home from Buffalo on Sunday night, I stop for gas and come out of the station making a left turn. BAM! I plow over the end of the center island with my front passenger wheel going about 30 KPH. I pull over to check to see if the wheel is ok and I see that the impact ripped my tire sidewall and left a SMALL divot on the lip of my wheel. It didn't blow out or anything, and the wheel didn't seem bent, so I continue the drive home and went to get the tire warrenteed today.
While at the wheel shop, all the guys were sayin' that I was lucky I had forged wheels and not cast ones, or else I might have had to pay for a new wheel instead of just a tire. Apparently, if I had cast wheels, I probably would have bent the spokes or at the very least put the wheel out of round. As it stands, my wheel is still true and still holds air. I'm feelin' lucky. My next car definitely gets forged wheels again...especially if I have less than a 60 series tire.
Next, I get to see if I'm still lucky and only need an alignment, or if I need new suspension bits....

Haha...i was slapping myself the whole way home. I can't believe I did something so stupid... but no excuses...I made a mistake and I paid for it. done and done.
What makes BBS soooo expensive ????
Not all of their wheels are forged right ????
they are just casting wheels.
Because their light weight ? is that all ??
I have experience with metel being that I am welder so I can kinda explain how forged is better than cast.
Cast steel is bits and pieces of metal melted making it whole. It is not as good becuase it is fill with other substance to make it hold together. I guess you can say it is contaminated. This makes the steel brittle or it can be soft depending on the metal.
Now forged steel is the refined metal heated up to so it can be shaped. No other outside sources are used. The metel is hard but not brittle.

Ok..so you melt metal together and pour it into a mould when you cast a wheel, thereby introducing impurities and air. You basically hammer metal into the final shape when you forge....but how does the metal that you're forging get into the shape before you start to work on it? doesn't it have to be cast into the disc or whatever shape it is from the foundry?

Ok mr.expert. I dont think my rims were made of steel, atleast by whole ;P Besides theres several ways of casting, gravity feed, pressure feed, etc. Gravity feed casting would make the wheels weaker, because the material fills the mold unevenly, this the material would be weak an porous. Pressure casting is what most wheel manufacteurers use. They pour the mixture the mold with pressure, which helps even distribution of the mixture. This would increase the strength. Just because you know how to weld, doesnt make you a metal expert, hell I work with welders and I know a thing or two about metals.
