Orly? What can you do with a clutch that you can’t with the SMG tranny? You can ride the clutch and burn it out (good job), you can drop the clutch at higher rpms to do a launch (which launch control will do better than you anyway), or you can do clutch kicks to get your back end loose, which is debatable, some like to drift, others don’t.
I wouldn’t get an M3 with an SMG tranny, because it’s a $10,000 option or some shit like that, but no sense complaining about getting it for free on the Skyline.
