Maxpeedingrods coilover suspension registration – experiences?

Hey guys, has someone here ever had a Maxpeedingrods coilover suspension registered in his car? I have a manufacturer’s declaration, but no TÜV parts report, and I wonder if the registration is still possible. It’s about the following vehicle: • Brand: SEAT • Model: Ibiza 6L • Year of manufacture: 2004 • Engine: 1.9 TDI, 74 kW (101 hp) • Axle loads: • Front axle: 920 kg • Rear axle: 784 kg If someone has already got the suspension registered or has more detailed information about it, I would be for Does anyone have an examiner or a workshop that knows how to do it?
