Double clutching won't solve the problem you described. It is unrelated.

What it will do is save your synchros. However, that is also kinda irrelevant for most drivers here.
But no one can claim we have a smooth transmission in our Crossies.


However, if proficient in the double clutch, downshifting improves dramatically. This especially in the lower gears. Going from 3rd to 2nd is much easier if you double clutch. Going to fifst while in motion, is almost impossible unless one double clutches.


The process is simple.
Press in on the clutch
Move the shifter to neutral as you let off on the gas..
Release the clutch momentarily and depress it again.
Move to the next gear.


If shifting up, do nothing else.
If shifting down, press a bit on the accelerator when in neutral.
(This works better if you have a sprint booster. If not, the pedal lag will drive you nuts)


I use the tranny to downshift and brake the car's speed. It cuts down on brake dust and gives you more control, especially in turns. It is why I originally did not buy and SRT6. No manual tranny was available. I now own one of each, and NA roadster and an SRT6 coupe. Love both of them but still prefer the pleasure and control acquired by rowing one's own gears.


And now that I have painted a target on my @ss....., have at it guys.
