Plus who downshifts into first at speed ever, even if your autocrossing you never downshift into first.
If your heel toeing, double clutching is useless.....both do the same exact thing. that is sync up the input and output sides of the entire drivetrain.
Incorrect. There are three things you need to match speeds on.
1) Input shaft
2) Output shaft
3) The gears
Heel-toe matches #1 and #2 but not #3. A synchro tranny helps match #3. If you've ever tried to downshift to 1st while still moving you've probably felt resistance in the gear shift lever...that is because you're pushing on the synchros and that pressure sort of gets translated into them trying to spin up the gear you're trying to mesh with. This wears the synchros out eventually (and since 2nd is one of the most commonly downshifted to gears, this is why 2nd is the first one that "goes out"). If you double clutch with a throttle blip you can bring up the gear speed without wearing the synchros. This is true of all downshifts, even from 6th to 5th.
You are also dead wrong on the lack of need to downshift into 1st in autocross (and other forms of racing as well). The nationally competitive S2000 autocross drivers largely downshift into 1st, even on National Tour courses. Some Lotus Elise drivers also go to 1st on some courses. It's a little less obvious in the case of the Elise...Matt Braun who won a national championship in the Elise almost never went to 1st on national level courses, but many local courses have slower corners. There are some cars that never even get OUT of 1st gear on an autocross course. I know of one guy who was paraplegic and drove a Corvette ZR1 extremely competively...one reason for his choice of a ZR1 was that 1st ran out to ~60 mph in that car. On many courses he never got out of 1st.
FWIW, even outside of autocross there are many road courses with corners where a car like a ZR1 or a Viper will want 1st gear leaving the slowest corners.
Shoot, I have a car that 1st runs out to 45mph...I go to 1st while moving almost every time I drive that car on the street, much less on a track or autocross course.
|trust me when I say this, I am slightly better than most people while driving a car. A quick search of my name and car I drove on google could prove that.
We could get into a penis waving contest about who's the better driver here, but we'd both just end up looking like fools with our privates hanging out.
