Roof platform, with bolt-in frame or non-drilled clamp, Metal or Alumnum？
Which ways are better?
After nearly a hundred discussions with customers on platforms installation, our view is that the six-series aluminum platform is the preferred option. Aluminum is lighter than steel, has a beautiful appearance, does not rust, and has sufficient strength.
However, according to the different vehicle models, and the customer's attitude towards the car modification, they chose different solution, but we are optimistic about screw fixing and clamp fixing!
