Ne razumijem ni ja. To sam pročitao u ovom članku:
The S40's stock brakes would never do behind the dubs, but Peter was again scuppered by the lack of decent aftermarket goodies available for the Volvo. "I needed a brake upgrade and Brembo did a Gran Turismo kit for the S60, but not the S40," he said. "So I got the S60 kit, hoping the pieces would fit, but they didn't. I needed new brackets for the calipers and modified the hub adapters on the discs to fit. It wasn't too tricky, but some cutting and welding was needed."
