which one is stronger? i mean if i were to hit a pothole, which one would less likely to bend?

i was planning to get either the gram light 57S pros (2 piece cast) or the sf challenges (2 piece forged)...

 

forged. however, given the wheels you listed both are great choices. the casting process Rays use is much better/stronger than the casting process others use. ii'm almost positive the Volk GT/SF series are cast center, and forged outer if they are 2 piece wheels.

 

Cast is stronger, BUT it wont bend it will break. Forged is WAYYYY lighter and will bend and the good thing is you can get them fixed. Casy you cant.

 

actually forged has a better strength to weight ratio.

 

I guess it just depends on the wheels. My buddy owns a wheel shop. Ive seen a LOT of bent forged wheels. I dont drive my car that much and Ive had two bent rims. In my city the roads are pretty good.

 

Pound for pound, forged is stronger. However, the bigger the wheel the more likely you will bend or break something. I've never heard of anyone bending a forged 18", but I hear about 19's alot...20's? forgetaboutit. The Volks SFs are spun cast outers and forged centers. SSF cast wheels fair a little better though.

 

were the bent ones you saw volk wheels?

 

I was in the aftermarket wheel industry for 5 years...and I have to agree w/ G352NV:

CAST: don't usually bend, they crack/break

FORGED: will bend, but in many cases fixable

However, your choice should really be based upon how you'll be using the wheels. What I'm saying is, if you care much about performance (in which case, the lighter the better), then FORGED is always the way to go.

The reason most people go w/ CAST is usually due to cost. Casting is a much, much cheaper & faster method of mass-production. A 2nd reason (which happens to be due to reason #1) of more cast wheels out there is more style choices. There are only a handful of companies out there offering forged wheels...hence, less choices/styles. On the other hand, there are hundreds of brands of cast wheels out there. Many of their offerings are copies of forged stuff...some really good looking ones too!

Basically it comes down to 2 questions:

1) Can you afford FORGED?
2) Does the style you want come in FORGED or CAST?

Hope this helped...^-^

 

Here is an article about forging & casting from tirerack.

From what I know, I think its the other way around. Forged wheels tend to crack or break. Forged are stronger and more dense in metal so they tend to crack or break in major/strong impact.

On the other hand, casted wheels are softer and not as dense, so they tend to bend easy instead of cracking or breaking on impact

Thats why many european wheels are considered soft because they are cast except for few wheels maker like BBS & OZ. Some of their wheels are forged.


In both cases, if there is a major/strong impact, both will crack or break.

In general, Forged is definitely stronger/lighter than Cast and that is why race cars tend to use Forged. Some also use magnisium.

You also have to take into consideration who make the wheel. Some of the BBS wheels are cast but they are considered just as good as forged because of their wheel making technology.
