TESTING DATA AND INFORMATION, TUV CERTIFIED
■ TESTING PROCEDURES
All of our forgings are initially engineered around a certain range of vehicle fitments / load ratings. Normally we design the forging die itself around a 2000lb. per corner load rating umbrella.
This means that so long as all wheels using this forging are engineered around the tested / certified material thickness minimums based on the test certification, no further testing is required unless an order violates these guidelines for any reason. To give you an example of this, see diagram below.
For any wheels which do in fact contain material in some areas which is less than the tested / certified guideline minimums, we then use our in house radial fatigue testing equipment.
An example of this would be on wheels like our new SL series where they are engineered for the exact vehicle the order is intended for thus the material thickness tolerances may be too conservative for the subject vehicle in question.
For example, if we’re engineering a set of SL’s for an R8 like the schematic below illustrates, the load rating of the vehicle is much less and the necessary material needed for safe use on this vehicle may be much less than the originally tested 2000lb / corner rating. With this being said, we use FEA analysis software to effectively determine the necessary material needed for this car. Once finalized, a physical test wheel is made for destruction testing on our radial and fatigue testing equipment which we’ve obtained for this exact purpose. Based on the resulting data of the test we then are able to confirm or deny the file which leads to either production of the wheel. revisions to engineering and re-testing, or additional reduction of material in order to further tweak the file for maximum weight reduction.
■ strength and durability testing
Every ADV.1 wheel is designed and engineered to meet the German TUV standards as set forth by the German transportation authority, the KBA.
We first simulate the test loads using computerized FEA load parameters and formulas provided to us by TUV Austria. Each vehicle has a different load requirement, even front to rear.
On wheels that receive the TUV Certification, we supply testing samples to our TUV partner in Austria and they subject them to the grueling TUV test sequence.
We also have a cornering test machine in-house that we use for daily testing and evaluation.
■ ALL WHEELS TESTED TO: SAE J2530 TESTING STANDARDS
■ IN HOUSE RADIAL CORNERING / FATIGUE TESTING
Our in house radial cornering / fatigue testing equipment also provides documentation on each subject tested. An example of such is shown below:

■ TUV Testing
In regards to TUV Testing, as many know is something we’ve been working diligently towards with our German Partners, ATT-Tec in Rastatt, is a long process and despite what many believe is actually a never ending requirement needed for every single size, offset, application, PCD, etc. The process is very expensive and time consuming however is the only way to provide customers in Germany with aftermarket products of any type. Below is a detailed explanation written recently by Jordan Swerdloff on this subject:
“After nearly 2 years and thousands of dollars our partners in Germany, ATT Tec have finally done it! ADV.1 Wheels is now an approved TUV manufacturing co. registered in their database. What this means is that our manufacturing methods, materials and test standards are all up to TUV’s strict requirements and our wheels are tested / approved for use in Germany. What this does not mean is that our wheels do not require testing and can be sold freely in Germany however the initial process of testing and approval to even be registered with the TUV is really the most difficult part of the process. Now that the company is registered and added to their database we can begin the process of individually testing / certifying our wheels in each style, size, and application. In order to simply reach the point where you can submit wheels for testing approval you first need to bring all manufacturing methods and materials to TUV standards.
TUV requires individual testing and certification documents for every single wheel style, in each size, for each application so there’s still a long road ahead of us in order to be able to offer all styles to a wide range of vehicles. So far we officially have our ADV5.1 monoblock approved in 20×8.5+18 / 20×11+20 for BMW e92 M3. Each additional certification will only require roughly a week for testing / approval now that the TUV recognizes the company as an approved manufacturer, the majority of the paperwork and testing is not needed for each additional certification. Current plans for the remainder of 2012 will include 18 more certifications, 3 styles in both 1 piece and 3 piece track spec configurations, offered to 3 different vehicle platforms.
Although there is still a long way to go, this is a huge step in the process of opening the door to Germany. Currently the selection of wheels able to be sold is very limited and the only option enthusiasts have is to either choose from the limited selection of approved brands, mostly cast wheels or to risk fines and even the loss of their vehicles by driving without TUV certified products on their car. Now, through the efforts of our Exclusive German Distributors ATT-Tec, the German market will finally be able to enjoy our wheels without having to worry about the consequences of driving without approved aftermarket components on their vehicles.”
