Re the Mac 12c, personally I find it 'detached' as a driving experience.....similar to a 911 TTs. 458 and not necessarily a Speciale would get my vote.
As detached as every other modern highly electronically heavy car.... as the 991 gt3 is.Though the 12c in particular has very very little turbo lag.
It is ferociously fast --- but much less "in your face" than equivalent F cars ---
And so clever, in all weathers.
Some would say it's a shame that the Iris 1 system is so poor, --- others would say that the driver should never notice
And all for the price of a 997 GT3RS !

It's the same mechanical LSD setup as per the previous cars. It's designed to sit in behind the electronics of the PTV which amongst other things apply the rear brakes to mimic the behaviour of a traditional LSD.
Thanks Neil. I assumed that was the case as the lockup figures are so low. But the wording make it sound like a true e-diff. I guess this is going to eat through rear brakes on track then
Some interesting technical info on the PCA Video here.

you turn PSM off, it will be fine on track
Even with PSM off the Torque Vectoring and braking assistance for the diff will still be active. Both of those will be eating brake pads. Turning off the PSM may help a little but it's not going to help the car using the brakes while you're trying to accelerate and corner. jackwood said:

Sounds like you've identified a critical flaw. You'd better let the guys at Weissach know.jackwood said:

keep your 996 GT3 then !acey81 said:
The GT4 is over-tired, so I doubt it will be much trouble for most drivers.
Torque vectoring has nothing to do with traction loss. It brakes the inside rear wheel on corner entry to help turn the car in. Obviously it does affect brake longevity, just one more reason why I wouldn't choose PCCB for a track car.Gassing Station | Porsche General | Top of Page | What's New | My Stuff
