Steel rims picture thread

Now most steel wheels (steelies) are not an optimized design for aesthetics (obviously what you are after) or performance, there are wheel companies out there that make nothing but true track rims from steel....have you ever seen an aluminum wheel in nascar? and why not do you think?

If you are taking a design all the way to the edge (which no aftermarket street wheel manufacturers do for public consumption) than you will end up with a magnesium, carbon, or billet aluminum wheel...but none of those things are even on your shopping list,

Please educate yourself before you attempt to educate the rest of the world...and no reading the rays catalog isn't education try some books published by forges (reynolds or kaiser for AL and Jorgensen or carpenter for steels) and then try to understand what is actually going on.

Oh, right, because the stock wheels on the BRZ have so many fatigue related failures

Your logic is fundamentally flawed. Sure, I'd put my money on a ~17-20 pound aluminum wheel failing before a ~25-28 pound steel wheel. But what situation are you having aluminum wheels fail? I haven't seen any reports of that happening on the twins.

Sure, in theory, you're running the aluminum wheels at a higher load, but if you're still well within the safety margin of the material, who cares? There's no benefit to swapping an aluminum wheel out with a steel wheel weighing 8-10 pounds more unless you're cracking aluminum wheels on a regular basis. It's just bad news for performance. You don't get extra credit for completely overkill solutions when it comes to vehicles where weight is bad for performance. You could pop on some big ol' train wheels and drive your BRZ on the train tracks and I bet you'd never have a flat tire or a cracked rim either, but that doesn't mean it will be faster. You could throw 400 pounds of steel bracing into your BRZ and give it a wonderfully stiff chassis, and it will be slower than mine around the track.

There's absolute reason to run steelies unless you're esthetically retarded or absolute broke (in which case you should've even modify at all).

just sayin'

Even the latter reason isn't a good one. Go look through the internet, and I'll guarantee that you can find a set of alloy wheels that fit our cars for less than the 17" steelies on Tire Rack that people here buy because they're 'cheap'. Yeah, have a fun winter on 28 pounds of steel, I'm going to be having a more fun winter on 16 pounds of aluminum that I got for cheaper because I took the time to figure out what wheels will fit, search classifieds to find a set for sale locally, and drove a little bit to pick them up.

wow...so you missed the part where a well engineered wheel from steel would weigh less than the aluminum counterpart because you have to allow in the design more material in an aluminum wheel because it has lower fatigue strength?


I never stated any of what you ASSumed, but you obviously have little exposure to reality, lots of aluminum rim failures occur all the time. it's not a theory, and you are not going to have such an issue with the factory rims i never even suggested such a thing, no one was in here talking about oem aluminum rims...are you lost little boy?

I see how you are trying to be cute and look all smart and stuff but you misunderstood everything in my post and simply look like a 13 year old child now. thanks for the laughs...this is where i'd say cheers but I don't want to be accused of encouraging underage drinking.

Oh, I must have misunderstood the thread. I thought we were talking about typical cheap steel wheels for passenger cars, specifically with regards to the twins. Didn't realize that we're having a theoretical debate over the best materials to use for a custom designed wheel for a race car. Maybe the fact that everyone else besides you was referring to regular ol' steel wheels was what gave me that impression.

Point still stands - you'd have to be an idiot to put steelies on a BRZ. Are you going to contest that? I'd hope not, you seem smarter than that.

You may be right about being able to design a steel wheel to be lighter than an aluminum one, but that's clearly not the type of steel wheel being discussed.

e-peen sword fighting in this thread.


On topic - I came into this thread hoping (and really hoping not) to see a FRS/BRZ with Diamond Racing Wheels. I'm glad all I have seen is regular steel wheels.

They would be fun to drift, they are always available at the junkyard..actually thats not a bad idea, i can use some to learn how to drift..lol

+1

Your typical steelies will not only be heavier, but flex like soggy cardboard at their limits. Ever wonder why hubcaps always fly off in those old car chase scenes?

I've handled plenty of oem wheelsets in my life, and usually I don't even need scales to know that the aluminium set are a lot heavier. Ok the alu set is usually one size up but perhaps that is a point also - oversizing. Edit: and hate to burst you bubble, but 99% of aftermarket aluminium wheels are designed for looks first, not for light weight, and although the choice in lightweight rims is better for this car, this is not because of US manufacturers or trends...

As for flex, for smooth track racing flex is bad, but good handling to me is not necessarily the same as superstiff chassis set-up, as some controlled flex actually helps on a bumpy back road, just as suspension travel is not an evil invention necessarily :p

Anyhow, if you greatly dislike the idea of a steel rim, why not just NOT read instead of being all negative and spoiling a PICTURE thread...

anyone know any steel rims that will clear STI Brembo?

The center of mass is add always in the middle, unless you need balancing done

I think I understand what you're trying to say but that would be wrong. If your rim is lighter, the moment of inertia will still become lower even if relatively more mass is in tje tire.
But indeed geometry comes into play also, and a smaller rim will be better than a bigger (tire and rim weight the same) because the mass of the barrel will be closer to the center...

i think it looks lame and cheap but apparently it's a popular look with a niche group of youngsters these days. http://www.diamondracingwheels.com/

Brought back from the dead, steelie apocalypse.
All those FRS/BRZ look like they either got flat tires or were in a accident, thats normally what you see in Junkyards....because its junk!!!

[calmtigers]

I'd love to see the twins on some deep dish steelies

[Trettiosjuan]

Hmm. Revived? Really? Only found one nice picture here yet - no pride with steelies apparently.

That's ok, just seems I am that weirdo here with priorities like this:
1. Function
2. Cost
3. Looks (I cared enough to start a picture thread, no luck)

Instead of this (my observation only of the wheel section):
1. Looks stance
2. Looks bling
3. Looks functional
4. Cost
5. Function

LOL
