Yeah your right your street car produces more power and potentially hooks up better than a street car did 30 yrs ago. But the wheels we are discussing were designed for racing 30yrs ago so which is still more than your street car and your street car on the track.

Lets just say your right a wheel is totally different now than 30 yrs ago.

Even though a pound is still a pound and horsepower is still horsepower and torque is still torque its all measured and rated the same now as then.

You ever heard the saying dont try to reinvent the wheel.

The wheels on our street cars are the wheels used on race cars in the 70's and 80's.

Yes, I have heard that. But if all of my mom's sayings were true, I'd be a piece of pizza.

Was not trying to single you out. The ad hominem was simply getting pretty agressive.

All I am saying is that wheel technology does not change like other things in the world. The cornering, braking, accelerating loads on a xxxx pound vehicle are the same now as they were 30 years ago assuming the vehicle weighs the same and the weight is in the same place. Once a person could design a wheel for those loads they could probably figure out how to design other wheels for those loads without being an engineer.

Pretty much agree all around here less the correction pointed out that tires are much grippier and speeds higher than 30 years ago for the same weight car. Thus these loads have changed in size but not really in their nature so in that way a load is a load.

So yes through testing almost anyone can design one wheel to be as strong as another existing design. It is more my concern of ones ability to properly extrapolate from one given known good design to one with different loads, different widths, different offsets and even a different shape (same visual design but in the details actually different to accommodate width/offset changes). This takes good engineering, pure and simple.

i stopped at page 9 or so, BUT seriously ADV.1..... pictures don't prove anything. for all we know, that picture (you guys at tuv) says 1000 words, not one is the proof of tuv and blablabla certification.

if you want to be held in the upper echelon in the wheel world, then just prove that so-and-so designs have tuv certification. we don't want pictures of certificates or stupid pictures you guys once took on a trip. just provide proof and it's done. I don't see why this is so hard.

you'd rather have a pissing fight with a consumer (while the whole world watches) than OWN UP. oh yea, annnnnd i'm not going to buy your rims anymore.... pitty, because they're fucking SEXY.

Sack up, champ, and put away the maxi pads. Show up proof!

[rickhunter]

2 week later, no response?

[PINHEAD]

where is the TUV cert. they promised months ago saying it was in the mail etc. etc.?

pathetic

[M3PO]

Where is Vossen's certification?

[FruitCake]

ADV.1's rep is so fucked its hilarious. So are the resale value of every ADV.1 rim out there on the forum, who's gonna pay that price for non-certified junk. lulz

[db71]

I have an idea how about everyone show proof of certification for the wheels they have on their car that is for that car and then we can start asking where other companies Certs. are.

So how long does processing take?

unless something has recently changed, that is not correct.

Forgestar does state on their website that they are JWL, VIA and SAE certified.

I mean how do we find out...here is their website in which they specifically state this..

http://www.forgestar.com/v2/about.php

I have no dog in this hunt..just as a potential consumer how do we find out such things? I know people in 997s and M3s that track their cars with Forgestar wheels with no issues. Doesn't mean something can't happen. How we as consumers can do our due diligence.

Here is their test data page..

I know APEX had a website that showed their wheels being JWL/VIA tested.

Thats cool...just that Eddie from Apex racing said that Forgestar didn't do this...how do we end up knowing the truth. Maybe its just Eddie bashing a competitor.

Everything I've ever seen from Eddie has indicated that he's a straight shooter.

The issues I've heard with Forgestar over time was that some of their wheels were certified at a low load rating and that when they provide a custom offset by cutting the wheel mounting surface, those wheels then differ from the certified configuration and it's unknown whether the modified wheel would pass certification or not. It's been a while since I've heard these issues, and they may no longer apply (if they ever did).

He had a link where you could look up the certified wheels that showed the APEX wheels and sizes that were certified.
Besides, if you bash another sponsor here, you get the ban-stick. Ask Benvo about that.

who did benvo have beef with? roman?

Some vendors are more important than other vendors on this board..this had a lot to do with it....

Forgestar isn't a vendor on here I believe. I know **********s and some of the other outlets that sell them are. I know Apex makes great wheels and have an excellent reputation as a strong track wheel.

The actual reason for the ban was a side issue with Roman, lets just say it was a force multiplier..

Im not talking any issue with Eddie...the issue I have is they say they aren't JWL, VIA or SAE certified. Yet if you go to Forgestars website they are showing all these certifications.

My other issue is how do we validate these claims?

Regarding the issue with Forgestar, they have resolved that issue.

At least once again, as I have been told...who do you believe?


Oh, and sorry for answering each post individually..I'm exhausted and didn't feel like combining them.
