I double clutch, toe-heel, and all the other fun stuff. Then again I also drive a car that needs these things done. 70's britt cars FTW!
Yeah, I agree it's not necessary, but I've seen some benefits to this in my own driving experience. I typically reserve this type of shifting to cases where I'm under hard braking and entering a corner, when I need to drop from (xxx-20mph). I rev match all the time, we all agree it helps with control and wear & tear. But when I added the double clutch technique my gear selection went from good to butter smooth. It just gave me more confidence during these situations that my shifting would be smooth..while minimizing the stress to my transmission. I still have to learn heel/toe:yumyum:
Once you get these techniques down you'll do them all the time without thinking about it. Then if you ever do track days your instructor will compliment you and you'll save yourself a blown head gasket, broken tranny, or worse.
I do all this stuff, poorly, but I try anyhow. Except heel toe. On the LGT the gas pedal is much lower than the brake, unless I'm slaming on the brake, I can't reach the gas with my foot. Is there a way to adjust these?
That is perfect!!! You want the gas and brake at the same level when trail braking. If you want your brake and gas closer together you can do a couple things. First thing is the pull the gas pedal out and reshape the rod that holds the pedal to give you that extra room. With that pull off your rubber pads from clutch and brake pedals, replace with skateboard grip tape. twice the grip none of the thickness. Or you can add ricer pedal covers to the gas only. I wish I could get you a pic of the setup in my neon. The gap between gas and brake pedals is only about 1/8" and under trail braking the pedals are level with each other. Makes toe/heel so much easier.
Well, I taught myself in steps. Here, I’m bored, its early, my 5 day vacation starts after today… maybe this will help you: Foot Position/blipping the throttle: Position yr right foot so that yr heel is firmly planted and the ball of yr foot sits almost directly between the brake and the gas. I would suggest favoring the brake a little more . Make sure it’s a comfortable position… helps if yr a little bowlegged … can’t help you there. Yr foot doesn’t have to be straight up and down in this position, yr toes should actually probably be pointed a little out. This should be a position where if you press straight down, you will be hitting mostly brake. If you pivot yr heel outward by pushing yr knee and rolling yr ankle away (but keeping yr heel planted) you should be on the gas only. If you do the same inward, you should be on the brake only). Next, position yr heel front to back so that you are making solid contact with the ball of yr foot (favoring the big toe side) when you press down. Now practice with the car on, parked, and in neutral. Press down on the brake. The outside (little toe side) of yr foot should barely touch the gas. Slowly roll yr ankle over until you hear/see the engine rev a little. It was easier for me to learn this barefoot before I practiced it on the street (empty street, coming to a stop, slowly blipping the throttle while braking and slowly learning to modulate the throttle when blipping). Double clutch down shifting: Rolling in 3rd at around 2500 rpm on an empty street, let the car cruise off throttle. Once it gets to 2200ish rpm: 1)depress the clutch 2)throw it in neutral 3)release the clutch 4)blip the throttle to anywhere between 3000-4200 rpm, depending on how slow you are. 5)Depress the clutch 6)Throw it in 2nd 7)Smoothly release the clutch If the car jerks at all as it goes into 2nd, you’ve done it wrong. Heel/toe downshift: Put it all together. 1)Cruising in third at 3500 rpm, lightly squeeze the brake 2)While still lightly on the brake, depress the clutch pedal 3)While still lightly on the brake throw it in neutral 4)While still lightly on the brake release the clutch 5)While still lightly on the brake blip the throttle 6)While still lightly on the brake, depress the clutch 7)While still lightly on the brake and with clutch fully depressed, throw it in second 8)Release the brake and pivot yr ankle to favor the gas. Simultaneously smoothly release the clutch 9)Hammer the gas J Once you are comfortable with that, you can get quick enough to use this technique just before a corner. If yr quick enough and good enough, you should be doing all yr braking and shifting in the same amount of space that you would typically only be braking. Once you are really really good, you can add step 8.5 into the mix: 8.5) Reposition yr left foot so that it is over the brake and pivot yr right foot so that it is over the gas. This will really help in our (turbocharged, slow corner entry) cars. Not only will you be in the right gear, ready for corner exit, but by left foot braking, you can make slight mid-corner modulations in yr speed with the brake (while still steady on the gas) rather than by lifting off the gas and loosing boost pressure. I’m still a noob at left foot braking… got a lot of practice in this past Fall/Winter in my neighborhood though (lots of stop signs… learned foot position and how to modulate the brake with my left foot without slamming down). I’ve seen some people heel/toe without the double clutch, but as I understand it, without the double clutch, you are not matching engine and transmission drive pressures. Without matching the rotational speed of the input shaft, which is driven by the engine, to the rotational speed of the transmission, you’re really defeating the purpose of the technique…. But at least you end up sounding like a mad tyte Drift King (ebrake and power over drifting is for poosays).
I don't believe in double clutching. Because what I get from the honda guys is if you do this you win.:laugh: But, flat foot shifting with the cobb ap FTW!!
Whenever I ride 3rd to redline in my '05 WRX, I have a hard time shifting into 4th. Sometimes I'll miss or get a little bit of a grind sound. Is double clutching the answer? Worn clutch?
i only use dc when downshifting hard while braking. I'm not a transmission guy, but 3rd/4th shifting during hard acceleration? synco issue maybe or could be a pressure plate? I'd try scotty's cocktail imho...if you don't already have it in there.
I had to clutchless shift my old honda for about a month... until then I didn't think that car could be any slower.
i can only tell you what I've experienced...my answer is yes. I had redline ns in the tranny and it was way better than regular lube. then i started getting 3/4synco grinds like you...during WOT shifts. I switched to the cocktail and bam....mucho smooth and no synco issues. (I made the switched about 1.5 years ago....still no issues!
I guess I meant slamming through gears without the clutch while upshifting. Not so nice on synchros though but who needs 'em. DOGS!!! Downshifting is pretty easy to do without the clutch once you can rev-match well. You still use the method you use when double-clutching but without touching the clutch pedal. I used to do this in my turbo RS and still do it from time to time with the LGT. I like it better than double-clutching because I don't have to reach for the clutch and can keep my left foot on the brake.
I used to have to double clutch when i was using regular trans fluid, but now with syncromesh we're all good
