Change the clutch…

I’m just getting along with the idea…. Don’t want to wait until it’s too late…. Therefore my question to you. Is it only useful to install a repair kit or should the complete clutch be new? What recommendations do you have regarding manufacturers? I would describe my driving style rather as sporty…. I’ll replace the Simmerring on the gearbox for the reverse gear control levers. That’s my only siff point;-)))) nr. and where do I get it from? Are there any parts that should be taken on the occasion? Will the surgery go through with a friendly mechanic at the WE and I am grateful for every tip (work process, special features, important things) Thank you and l.G., Andreas
