It's also TYPICAL for a gravity cast aluminum wheel in that size.

This FORGED 6061-T6 is very strong; check out the robust size and shape of the spokes.

It is designed primarily as a street wheel with the realities of street driving (ruts, potholes, frost-heaves and expansion joints) in mind.

so you're saying my 9.9lb wheels will bend if I hit something?

is that a different wheel then the one on the first page?

I'm checking them and they're ugly as sin.

do you like the style? do you like the price?

then buy them, but they are not "light" when compared to the available wheels out there.

Yep, that's what I'm saying.

Any "racing" wheel will bend on roads like those we have here in the Northeast.

I've seen several Enkeis fold like accordians up here.

I don't have enkeis.

So my CCWs will bend on your roads? but they weigh 25lbs for a 17x10?

please help me understand your logic and where your basis of argument is coming from.

by adding more material increasing weight does not automatically make a wheel "stronger" then a lighter counterpart.

I've also seen higher weight wheels bend. Alot of times it's due to the tire pressure being overly low, or the sidewall height being too short for the type of road.

Wheels are designed to bend when an extreme situation happens, it's better for them to bend then break.

by your "weight" standards those 17" centerlines wouldn't put up to squat. So what makes you think their 15" version is worth anything? because the website said so? :lol:

I feel spoke design (less spacing between spokes), proper sidewall height, proper tire pressure, and as much as safe pothole avoidance is going to save your wheels more then adding 2lbs of metal somewhere.

I'm telling you that any "RACING" wheel isn't designed for STREET use.

Period.

That's because the barrel sections and the spoke sections are much thinner than what would be considered appropriate for STREET use.

Race tracks are SMOOTH, so thinner walls (which means lighter weight) are OK there.

Those Centerlines are thick-walled, FORGED 6061-T6 wheels.

They are MUCH stronger than any thin walled, cast wheel.

6061-T6's mechanical properties (e.g. yield strength) blow away the properties of cast aluminums.

Compare those propertied to A356 aluminum, which is the most common aluminum used in cast wheels:

question...

what makes a wheel a "racing" wheel? are AMERICAN RACING wheels RACING wheels because their name has RACING in it?

"A word on BBS Race wheels for street use
I see many inquiries and threads on these wheels, and I think it's fair to warn people that don't know that these wheels were not designed for street use and BBS does not recommend them to be used off of a track. The barrel sections are roll formed and they are considerably thinner on these wheels than they would be on one of their road wheels. It saves weight, but it makes the wheel much more likely to be damaged by potholes, etc."

Cast aluminum racing wheels are typically made from A356 aluminum and are very light. By definition they can't be strong, since the material properties of that aluminum are quite low and since real racing wheels use very thin walls (in the barrel and the spokes).

Here are the material properties of A356, which is the most commonly used aluminum in cast wheels. They are laughable compared to a good forging:

http://www.mse.mtu.edu/classes/my413...inum/a356.html

Centerline wheels are fabricated exclusively from 6061-T6, which is a forged, aircraft grade aluminum. They also use thick walls, since they are designed primarily for STREET use.

I'm just trying to understand your logic, you keep repeating the same thing over and over without actually addressing anything.

Would you consider a wheel that meets JWL standards good enough for the street?

The wheels I have are 15x7 +35mm Forged, so am I good to go?

I'd like to see a list of companies you feel make quality street wheels, just to get an idea of what you consider a "street" wheel.

I'm also curious if you're lumping all BBS wheels in with the "BBS Racing" wheels. I've had BBS wheels on my other car for ages now and they have held up amazingly well.

also, not all race tracks are smooth, and track wheels generally face more strain then your average street wheel. You ever hit a berm at 45 mph? those aren't little rumble strips like you feel on your xbox. :lol:

it's funny, I hear the exact opposite logic from people daily. "these wheels wont see the track so I don't need something forged/strong/stay in one piece"

and now you're saying that a quality wheel that is lightweight and forged is going to bend used on the street?

can you define "racing" wheel for us.
