I know a bit gloomy, but a healthy dose of reality
My 2007 had a rough life prior to me. 24,000 miles and 75% used on the clutch. No issues with it at all and I'll drive it until it starts acting up. It's a consumable IMHO, so it might as well be fully used.
We are on the same page. Most drive their cars so little that the difference is 10 years or 11 years until a clutch change, and likely more than that. Just like you do, I will play with my toys and worry about it later. In the case of a clutch, much later and maybe never.
Maybe your car had some track days and some really spirited driving. Not necessarily rough. To me,, that is a proper life of a car like a steed that raced in its heyday...
I did have to think about this for a moment...so banging gears at redline approximately 6-8 times a lap for 20-25 minutes at a time with transmission temps at its limit is not going to wear the clutch prematurely? I do understand totally the city driving in traffic and backing up a hill is the worse thing ever for the clutch though.
No, it is the slipping that wears clutches. Very little wear on the clutch from banging shifts, especially since the system matches revs on upshifts and downshifts. Incidentally, reverse is not bad at all in the 599, especially compared to the 360 and 575M, where it is almost as high as 2nd gear. First in a 599 is 3.15:1 and reverse is 2.93, pretty close and not enough to worry about rapid clutch in reverse.
One thing that you should think about. Very often the throw out bearing gets leaking with the years. So you have to open the system to install a new throw out bearing. Mostly this is the time to install a new clutch also. In that cases, the clutch often has wear, but labor costs more to open the system again some time after the new throw out bearing was necessary/installed. my opinion : Clutch is good for 70-80.000 Km at normal use and driven with brain. Throw out bearing is good for same km, but risk of leaking at about 12 years (or some more) So you can calculate what happens earlier at your car, and i'm sure, most will have situation nr 2 first, a leaking throw out bearing. So better not to think about the clutch wear. When it get's time, it get's time. Daniel
