Hello fellow Volvo lovers!

I have a question regarding the cluth disc size for my S60 with the B5244S2 enigne, a 2.4 petrol with 103 kw (140hp). My clutch is really hard and will need replacing very soon, but I am having trouble ordering the right clutch for my car. As I was looking around, there are 2 options, one is from LUK and has a 230mm clutch disc size, and the other is a SACHS clutch with a 228mm disc and 20 teeth. Does anyone know which is the right one? The pressure plate OEM number is the same on both clutches (272449) but I can't understand why there are 2 different dimensions of the clutch disc. The car is a 07/2001, and a 2002 model has a different pressure plate OEM number. This is the site where I want to order: https://www.autodoc.si/search?keyword=272449

Please help if anyone knows the right dimension for the car. Thank you in advance,

greetings from Slovenia.
