cant say i have ever understood doubledeclutch.
i think, because, despite being very good with mechaical things (you will just have to take my word on that) i just cant get my head around what the damn thing is doing in there!
i always always try and match the engine speed to the wheel speed, well enough so i can drop the clutch instantly, and have no jolt in the transmission (rather than slipping it slightly)
when driving twistier roads, this often involves blipping the throttle, and heel and toeing into the corners to change gear without upsetting the balance. Just because i can.
So i get matching the wheel speed to the engine speed.
what does double de clutch do that a throttle blip doesnt?
