ALUTEC For BMW E46 316 / 318 / 320 / 325 / 330 4 & 6 CYL M3 Front Tower Bar - B3301
For concerning about the style shape of the bar, we re-design the construction. We modify the whole set of structure without changing construction strength. According to this, we could have more streamline and brilliant looking.
The mounting is all made by CNC and the appearance is much better than the products which are made by the press machine. Furthermore, the hand welding for the mounting and the bracket makes the balance and the torque more effective.
The mounting is used by the aerospace quality aluminum material. Its high hardness provides reinforcement between the top of the shock absorber and the body. This can prevent the shape changed. For the material that we use for the bar is Aluminum 6061, which is more flexible than Aluminum 7005. Due to its give, the structure of the bar won’t be changed when the bar and the car body are pulling and dragging.
By using aerospace quality aluminum material, the weight is controlled around 1.5KG to achieve lightweight
The bar is with inner twin I-beam cross-section design and the tensile strength of every square mm2 can bear over 35KG, which is 30% higher than the similar products.
