| give her gas befor down shifting?
sup all i just picked up an rsx-s a few days ago and im a bit confuzed about downshifting still, i had a stick car in the past but never bother giving gas when i down shifted, now that this car is much more expensive i would like to down shift properly..
someone told me u need to give it gas befor down shifting, now i've tried this so far and i dont know if i should hold the gas down a bit while releasing the clutch or give gas and let go of the gas, And then let the clutch go to down shift?

You really don't have to put in gas when downshifting... balancing it just makes it a smoother transition.

You don't HAVE to give it gas, as the syncro's in the transmission will compensate for the rev mismatch. However, it is not a bad habit to pick up as it smooths out the shift and it saves syncro wear.
Just blip the throttle (gas and let go) when you have the clutch pedal down.
Fk I miss driving a manual.

For example, say when you're in second and doing 60k, you're at 4000rpm (just pulling random numbers out here, BTW)... then if you're doing 60 in third and wanting to downshift to second, you'd rev up to around 4000rpm before releasing the clutch, so you don't get that sudden deceleration.
How you get there isn't really critical, so just practice it and use a method that's comfortable for you. As sonick says, you don't HAVE to do it, it just makes your driving smoother.
(I miss driving a manual too...)

Plus, if you rev-match perfectly, the shifter slides into gear slicker than a wet vagina.

So if I rev match I won't wear out the synchros? How long do they usually last? Do I have the let the clutch out once or twice? Cuz I heard some people talking about double clutching, but I'm not too sure why u need to press the clutch twice for one shift. Posted via RS Mobile | |

Granny shifting not double cluchin' like you should....
That's noob. Did you know you can drive without the clutch at all!!! Try revmatching and not using the clutch you'll find you can shift gears still. Crazy I know!
Berz out.

1.) Step on clutch
2.) Apply some throttle
3.) Downshift
4.) Release clutch
Steps 2 & 3 can be done interchangeably or concurrently.

Doesn't really help for actual shifter movement/engagement, or matching transmissioin input to output speed though. When you step on the clutch, you've now disconnected the input shaft from the engine and can't possibly raise input shaft speed. Unless it's raised using the synco's, via the output shaft (road speed). This last sentence is what caused wear on the syncos

Pay attention kids, this man is 100% correct.
It doesn't save synchro wear, unless Ur double clutching. It doesn't make the shifter go in faster.
All it does is make the transition smooth. Posted via RS Mobile | |
