Ultra Racing Bars - Material and Design, test with others bars
In order to reach the desired performance of Ultra Racing products, we constantly monitor the quality of our products not only during the production stage, but also conduct strict performance testing afterwards.
During the development phase of Ultra Racing bars, we ensure the products are in accordance to our design and development philosophy. We conduct real on-road performance test as well as on-track testing. In order to obtain data, we also invented three testing jigs, namely Bending Test Jig, Torsion Test and Flex Test Jig.hese jigs are used to test the performance of our products ona continuous basis.
The strut bar is bolted to the jig to simulate the actual situation on the vehicle chassis. For torsion test jig, torque is applied to one side of the bar, and the amount of twist is recorded. Torque used was calculated and fixed at 6.6kg/m.
For compression test jig, forces are applied along both sides of the bar. Maximum compression force is recorded to study the structure of various kind of designs that the bar can withstand under different driving conditions including impact simulating an accident. We use a hydraulic pump to compress at set pressures and record the results
For flex test jig, torques are applied on the ends of the bars to simulate the performance of the bar under chassis flex conditions. Torque used for the experiment is fixed at 8kg/m.
MATERIAL SPECIFICATION & DESIGN
Every materials used are carefully selected to ensure the best performance and safety. The brackets are made of 4mm to 5mm steel plates, while the hollow steel tubes and oval tubes are of 1.2mm to 1.6mm thickness. These materials are selected to ensure the bars are rigid and strong to maintain constant geometry at all times, yet safe enough to crumble during an impact for safety reason.
All our raw materials has been made and tested with satisfactory result.
To achieve safe condition, the displacement must be less than the thickness of the material which is below 2mm. Therefore, the bar is in SAFE condition.

STEEL VS ALUMINUM?
Why we use Steel instead of Aluminum?
First, steel is stronger than aluminum for the same size and thickness. In order for aluminum alloys to be at least the same strength as steel, it has to be at least double the thickness (steel 4mm = aluminum 8mm). When that happens, weight saving is not so apparent anymore. Of course there are also exotic materials and alloys that can match the strengths of steel, but the cost are astronomically high and therefore not very cost effective to bring into mass production.
