AST Lowering Springs Certificate

AST Lowering Springs Certificate – Swiss certificate of suitability for your AST springs

The AST lowering springs certificate – often simply called a springs certificate – makes your lowering setup legal. AST lowering springs put your car lower, sportier and more planted on the road. In Switzerland, retrofitted lowering springs must be officially certified – without a certificate of suitability your vehicle is not compliant at the MFK (vehicle inspection). We issue the certificate for your AST springs directly: ASTRA-compliant and recognised in all 26 cantons.
