Proper way to down shift?

if the Z's throttle response was quicker i would probably not use SRM but i found that SRM can blip the throttle faster than manally stepping on the pedal so ive been using it.

the Z's throttle lag is considerably longer than say my G's pedal input.

See, i think its quick haha. when i shift gears, i chirp them everytime even at 4th gear. Either the throttle is quick or im dropping the clutch too fast? is there such a thing? ive actually been meaning to ask that question..

you mean during a shiftup? if so you're sort of power shifting/dropping the clutch on every gear. quick way to get a shuddering clutch.

you'd have to learn to time yourself so that you dont get a lurch during engagement.

if you're chirping on downshifts then you're doing it all wrong!

you'd want to rev match by blipping the throttle and clutch-out gently...otherwise in rain you could lose control of the car~!!

sorry, should have clarified. yes, during upshifts, not downshifts. What exactly is a shuddering clutch? You really think its bad? When i do it, its not really jerky or anything, but yes, i am hammering down on that clutch lol. I get excited when driving lol

clutch shudder... hummm... never a subi owner, huh?

it's a clutch that vibrates kinda violently just as you are fully engaging the clutch. was an issue i had to live with on my 02 WRX long time ago. it's kinda feels like you're under-reving from standstill and car wants to stall.

i have this on my Fit because i beat the living shhit out of it at times since its so f-king slow.

like i would shift 1-2, 2-3 very quickly with the throttle on the floor at WOT (power shifting)

haha, nope, never a Subi owner, but I think I understand what your saying. Im new on the 370z, so I'll have to learn to slow it down on the clutch power-slam move ive been doing lol. If not, Nissan is going to live up to their warranty!!

You want to impress that cute girl over there (just be prepared...she won't be impressed. She'll think you are a loud, annoying idiot who doesn't know a think about what women want. She'll tell you this if you are moving slowly enough and your window is down).

Very true. It drives me nuts to drive the Z with the epic throttle lag. I find myself overshooting my matches every time I drive another car because I'm used to having to apply full throttle to rev-match.

hahaha, yah, i had this problem after driving my Z without SRM turned on and switching to either my G or Fit. both cars im over blipping and timing is off.

the Z's best driven with SRM-on i thinks.

ofcourse if this was my only car then no issue.

Perhaps changing the flywheel with a lighter one might give you what you're looking for?

It might, but I would rather flash the ECU if there's a simple fix for this. Maybe UpRev?

It's not the flywheel, it's how the DBW is implemented. My old Civic SI had it as well, albeit to a lesser extent.

I don't. I've only ever used it once (to try it out). I downshift depending upon speed, terrain (corners, etc.), engine revs.... you know, like you're supposed to.

BTW, op: if you need advice on how to properly downshift, then you need lessons. (And no, I'm not trying to be sarcastic.)
