Hey guys,

I need your help, maybe you can help me with a problem: Due to the fact that I installed TEIN s.tech springs, I have to present it to local authorities over here. Unfortunately, I don't have any data concerning the performance of the springs, material and so on. I just have the manual. Do you have any idea how to get certain data and facts that I can present to the authorities?

Thanks in advance.

 

why do you have to present the data of the spring rates to the local authorities?
but sorry i cannot help you out, i was just wondering why.

 

Every modification has to be approved over here and will be listed in the registration certificate of my car. Actally I thought that the approval would not be a problem but now they are demanding data. That's the problem with non-european parts here, they simply do not have a kind of report about the characteristics.
