Double clutch heel-toe downshifting.

the_student · 03-03-2010, 11:59 AM

I have been trying to heel-toe downshift in this car for a while now but it's not that smooth for me because the engine hangs on to the revs and I end up overrevving for the downshift. I have been double clutch heel-toe downshifting and that is much more smoother for me. I usually have synchrorev off bc I don't want to lose any skill. What do you guys think about downshifting in your cars?

i would just use synchrorev for the hell of it because its a feature you paid for. Also, it's designed to perfectly match it for you everytime.

I wouldn't worry about losing the skills...It's kinda like riding a bike. I've been using the Syncro rev since I bought the car after 40 years of double clutch downshifting. Personally I don't miss it! Every now and then I turn it off, but it's so good it gets clicked back on quickly.....Roll with the times!

But to answer your question, yeah, the revs are slow to reduce. It takes some time to get used to this...

to the op...you dont need to double clutch, keep practicing.

only time double or tripple clutch is useful is when getting into R or sometimes into 1st.

I know I'll be able to get it with more practice, but this car is harder to do it in for me. The situation, which I failed to mention, is during braking situations when you would like to select a lower gear like when you are slowing down and preparing for a turn and need the correct gear ready to pull you out of the turn. During those situations I feel as if the revs hang too long and it ends up over revving. I have to adjust to blip the throttle lighter than other cars to have a smooth downshift, but its so hard to get used to that especially since I have size 11 shoes and the footwell isn't exactly spacious. Anyway, I am just going to have to get used to it I suppose and practice...

"we talkin bout practice?"

you still like those pedals, huh, modshack.

i like the factory touring pedals bettAr.

Yeah, double clutching is not really necessary. I only use sometimes if I need to get it in 1st while the car is still moving. I too have found getting a smooth heel-toe downshift in this car is not that easy for me for some reason. I could do it easily in my wrx and even in my truck haha. So I just leave the SRM on when i drive the Z and keep up my hee-toe skillzz with my truck. I just like how the SRM works on upshifts too so it makes the driving much smoother. If i'm shifting reaally slow the SRM helps to prevent any jerk.

Why are you double clutching AND heel and toe'ing when you downshift? People still double clutch? I thought that died with the invention of the synchros...

Why do I think you're a little confused about what you're doing?

I mean...if you are actually doing all that on downshifts, awesome, but judging by your original question, Im not so sure.

It's like sex without condoms....The more rubber you can get out of the interface, the better it feels...

I will agree with the rubber part 100%, when I first got them I would partially get onto the brake pedal and my foot would slide a little. Moved over a bit and got on top of the pedal and it was great.
I just need to get some time to install the dead pedal at some point.

Well If you doubt me what am I to do. To me double clutch down shift is when I first disengage the clutch shift into neutral engage the clutch then rev my engine then disengage the clutch again downshift into a lower gear and then engage the clutch again and during that whole process I am pressing the brakes with the ball of my right foot and revving with the side of my right foot. I don't think I'm confused but whatever. I can do regular heel-toe also. I just stated it's smoother for me to double clutch heel-toe and am practicing so I don't have to do the extra step of shifting into neutral. I also know that noone really uses double clutching now adays unless you are running straight cut gears. So anyway back on topic. I'm about to go driving and gonna practice. Let's get some tips out there for people to get smoother at heel-toe.

I single clutch downshift the higher gears (6th through 3rd), but I double clutch downshifts under that, or when skipping more than three gears. Call me crazy, but my gearbox has slower, notchy synchros, and double clutching lessens the load on the synchros, and makes the shift feel better. I'll double clutch heel and toe going from say 3rd to second while on the brakes, and anytime I go back into 1st when I'm not fully stopped.

The 370Z rev hangs more than my car does, so the trick is simply being more accurate with your timing, and a little less swift on clutch take up. On my car I over rev, and pull the clutch out as the rev's fall down. In the Z with Rev Match off, you have to nail the throttle blip a bit better, wait for the revs to slowly fall, or clutch out a bit slower.

Practice practice practice and you'll get it. The 350Z was IMO a bit easier to drive smoothly, but the 370Z can be mastered with enough practice.

*EDIT I just saw that you're in the Bay Area. Feel free to drop by Boardwalk Nissan in Redwood City (PM me first to make sure I'm here), and we'll go out and I'll show you a few tricks.
