GT3 battery cutoff question, clutch & flywheel replacement


Vehicle Information: Model: 996; Year: 2001; Body Type: Coupe; Total Mileage: 45000;

Joel, I used to work at AutoThority which you no doubt have heard of before (now dissolved from original ownership.) I have seen Summit battery disconnect switches on Porsches, Ferraris, etc. can choose continuous and surge amp rated switches for the application, and they are relatively cheap around 20 to 50 bucks.I also wanted to comment on a question that came in about clutches and replacement. They way we always did it was putting the car on the rack, taking it up a foot after loosening all we could while it was on the ground, sliding in a floor jack, undoing all the hoses, stuffing rags, etc. Mounts are loosened after the floor jack has the motor, raise the car, slide the motor/tranny out, everything is right there. We could do this with 2 people in 20 min not in a rush. And the flywheel replacement I think is hogwash, I have seen clutches from 930's to 996's where the clutch was worn beyond the tip of the rivets (the driver was obviously noticing at this point something was awry, not everyone pays a lot of attention to their 911's which you must know) and there was some scoring on the flywheel, however, if the car was able to get to the shop under it's own power even with the clutch slipping, there was still friction material. Only in cases where the flywheel had a crack did we replace them which was rare. The rivets won't do enough damage to take any noticeable friction away from the new clutch grabbing the flywheel. I did like how you answered when the clutch can wear out, it's all about the driver! People should know this. We have shattered triple plated clutches before on our 650-700 hp Turbos, and the clutch had a few hundred miles on it, but we we're at the drag strip dropping the clutch at redline racing crotchrockets and beating them through the traps by 1-3 seconds, all in good fun...and $$$.
