Re: 991.2 GT3
Boxster Coupe GTS:fritz:Kobalt:Grant:Think the R's light flywheel will be option on GT3? Usually this is reserved for RS, but since RS is PDK now, maybe?
Good thinking!
Wonder if they change something more than the flywheel since it is rather expensive.
Single-mass flywheel is in fact cheaper than a dual-mass flywheel. It's just not fitted to other 911s due to poor torsional damping characteristics,not due to cost reasons.
Andreas Preuninger mentioned the single-mass flywheel option includes a heavy duty clutch...
Well, a stiffer clutch diaphragm spring would also not need to cost significantly more than a the standard one. It would be used in conjunction with a lighter flywheel to compensate for the abuse that a clutch is more inclined to be subjected to in a car more likely to be driven on the track.
As I wrote above, the heavier dual-mass flywheel is used in the "bread-and-butter" models to eliminate the gearbox chatter resulting from torsional vibration in the drive train at idle and when rolling at low speed and no load.
