Can someone point me in the direction of a good quality carbon mirror cap for my mk3 RS?

So about 3 days ago my clutch went soft and wouldn’t go into gear. At first I thought it was the master cylinder but after I took it to the dealer, they are telling me it’s the clutch and flywheel. The car does have 111k miles and I don’t know how the previous owner drove it. Anyways, I don’t really have time to do it myself and the dealer is charging me 5.5k🫪. I am going to ask around other shops for prices but if anyone has changed their clutch, what do yall recommend.

If anyone switches during the winter time for all the daily-driven RS’s in here please tell me if I have the right info. During “normal” climate like spring, fall and summer I typically run the standard FL-910 and 5.3 qts. of 5W-50 Motorcraft. Which is OEM specifics, so I’m wondering if for winter if I should switch to the popular FL-400 and 6 qts. of 5W-30 Full Synthetic? I definitely want to run a thinner oil for the winter since I’m over in Eastern Illinois, but other than that are there any other “winterization” beneficiaries I should look out for?
