Pedal stomp downshift (6MT only)

lol you should keep doing that with out knowing nearly exactly how much to match the engine to tranny rpms. I always wondered how much the syncros, gears, and even a new tranny in the 370z would cost.

I can tell you how much the syncos and gears cost in an rsx s... twice

lol

My recommendation for those of you that happen upon this thread

1. turn on SRM and don't worry about any of this... SRM will rev-match perfectly which does a lot of things... faster / more efficient shifts, can downshift safely in corners, less likely to damage or wear parts

2. or leave it off and learn to properly rev match... that may indeed mean that you have to floor it for a certain amount of time to get the revs up... but... be sure to return the throttle to the appropriate position as you re-engage the drivetrain... do not simply 'release the throttle' unless you really know what you're doing - that can be dangerous if you are downshifting in a turn

For those of you that don't like the slow responsiveness of the motor due to heavy flywheel, suggest you look into the JWT or other aftermarket flywheels which weigh ~half as much

It's much better for the tranny to try and rev-match and be close to the rpm rather than not doing it at all and downshifting IMO. If it feels totally smooth as if SRM was on than as far as I'm concerned it was applied correctly. Am I wrong by assuming that?

Really? I think the heavy flywheel makes it harder, at least when it comes to heel and toe, because you have to depress the throttle more to get the revs up, which can be challenging when half your foot is on the brake pedal. I much prefer being able to get the revs up with a less pressure. That's just my personal preference tho.

Anyone tell me if I'm safe to assume the bolded statement?

If you didnt feel your drivetrain cry out for help then yes you shifted acceptably...

I don't heel toe when I drive on the street, and I don't race this car so for me at least it's nice.
