What do you think of these? Need to play with the color and polish scheme a bit but it seems to have potential. I like the smooth lip better than the stepped lip of the Fikse wheels. And you can choose how deep you want the lip too.

I should know early next week if the Firehawk wheels can be made with larger brake clearance.

I have been a fan of the BBS mesh style rims since the early 80's. Gold center mesh with milled aluminum outer equaled road race car to me when I was 12 YO in 82. I have a real soft spot for them. Take a look at "big red", the 69 Camaro that kicked ass in top end shootouts for a long time. Same rims.

The BMW 5 series my wife drove for a couple of years had the same mesh BBS rims but in a machined aluminum finish and I loved them, even though they were a bitch to clean. The large flat portion in front of the center section made the tires look wider than they were, but if there was more girth behind the center section you could still see it.

3rd gens came with these wheels in the formula package, it would be retro cool to see a 18 or 19 x10"+ width on your car. A nod to nostalgia with a implication of much more modern power.

Well you're not going to like the wheels going on the 'Yota then, Jon. Laughing

Meshies are cool, but if they're not right for you then they're not right for your car.

The mesh is a worn out look and way over done these days. Everybody has a set, including Toyota trucks. And gold is not going to happen on my car.

Followed up with the engineer that designs wheels. He cannot replicate the Firehawk wheels very well because some of the features can only be done with a cast wheel. So that idea is now off the table now.

It seems Forgestar wheels are very strong but fairly inexpensive.

Strong you say? https://youtu.be/vtYjujhW27Q



The F14 is a good looking wheel if you don't go too oversized. 18" or larger makes them look goofy because they lack any sort of lip and it really highlights what rubber bands you have for tires.

That's amazing. Dude's pretty chill too: "Oh my God, that's awesome!!!"

Why is the 5 x 4.75 bolt pattern nearly abandoned? Almost everything is 5 x 120 mm and I am having a hard time finding what I want in the correct format.

I have been looking at some opinions on using the 5 x 120 mm bolt pattern but I am coming to the conclusion that most people with opinions can't do basic geometry and math. The difference is much larger than what they think.

What do you guys know about using the 5 x 120 mm pattern?

I know a couple people who've done it, but I wouldn't.

I don't like things that aren't right either.

If you think the 5x4.75 is bad.. try buying a decent sized 15" tire now.

.65mm across the studs, .68mm calculated out to the diameter of the bolt circle. Practically that means each lug is .34mm closer to the outside edge of the lug hole. What varies is whether that is within manufacturing spec of the wheel/hub/stud/lugnut assembly of any given vehicle.

Lug style plays into it as well. You want to be running conical lugs if you're doing nonsense like this.

Gabe, you had the Cragar slotted 4 1/2" - 4 3/4" universals on your truck forever, so don't go too far. Laughing

I would also like to point out that this is exclusively an old man problem. Kids around here bolt GM rims onto Japanese 114.3mm with four lug nuts and call it a day.

Slotted Cragars, while terrible as well, are a whole different ballgame from a conical lugnut misalignment.

If your hub center is a tight fit, you'll have lateral force on the studs and reduced contact area on the conical lug seat.
If the hub center is loosey-goosey, you'll pull the wheel around as you tighten it and have the above problems magnified on several studs as well as a wheel that likely isn't concentric to the hub.

I'm also curious if I'm being too engineer-y and a third of a mm misalignment is within tolerance for a wheel/stud/conical seat nut. With modern manufacturing prowess, I can't imagine that's the case.

I agree with you guys, not a good idea. Just wanted to hear if there are other sides of the argument.

Regarding bolt hole tolerance, I am accustomed to seeing positioning tolerance such as +/- 0.05 mm of machined surfaces where parts bolt to engines. I don't know why wheels would be much different.
