is there such thing as a perfect shift?

[Bmore_Raven86]

I adjusted the clutch engagement for my FRS just slight lower than the brake pedal and i notice a big difference, shifting is alot smoother making it earsier to ease off the clutch alot faster..I also notice the clunk that you hear when shifting is down to minimal....if so how would it feel like, for example shifting from 2nd gear to 3rd gear, i notice that the rpm drop drastically before this MOD considering you made a perfect shift the rmp does not have a major drop but continually catches making the car feels smoother and does not jerk back..is this consider a perfect shift?..

if you do it right, it should go in like butter. smooth and you cant even notice it at all. engagement point is just for personal preference, its all practice and working both pedals simultaneously in just the right way to get it right. if your rpm drops after you put it in gear then you didnt rev match right, you should be engaging the driveline at exactly the same rpm speed as the engine.

When you hardly feel the change in momentum during an upshift. Perfect...

Where is the adjustment for that? I'd like to do the same.
Forget it - i found the thread.

it sounds like the OP may have adjusted his pedal to the point that the clutch may be slipping.

Or maybe i read his post wrong, it sounds like he raised the engagement point to be quite high in the stroke.

Ratio between gears doesn't change with clutch engagement height, gear ratio is what determines the RPM difference between gears. if it has changed it is because your clutch is slipping when you shift.

If you are simply more comfortable with the new position and it is making it more natural for you to rev match...then YAY Kudos to you, otherwise you want want to verify that you haven't adjusted your clutch throw "out of range"

Hope this helps and doesn't add confusion.

I think he means he adjusted the shift point to the spot at wich the speed of his shifting makes him rev-match almost perfectly.

To the op, it's all a matter of feel and preference. Different drivers have different speeds and habits. That's why we customize.

the "perfect shift" is relative, but it's usually characterized by smoothness.

If you're driving around town, a perfect shift is timed just right, where the engine revs drop exactly the right amount and your clutch/gas action catches the next gear smoothly at just the right point, so you don't "feel" it. Ultimately, you and the passenger(s) feel zero herky jerky motion, you only feel buttery smooth acceleration with maybe a very subtle lapse between gears.

On a track, acceleration in a straight line needs to be quick, any time spent out of gear equates to lost acceleration and speed. You don't want to slam through the gears, but everything is going to full acceleration so you don't want to shift casually. The next most important aspect of shifting smoothly on the track is to avoid disruption of the car's balance mid-corner. Upshifting and downshifting need to be performed precisely and smoothly if you're under braking or cornering loads to maintain grip levels.

The clutch engagement point is personal preference, although a clutch that engages extremely high or extremely deep in the pedal stroke may not engage/disengage fully. This will manifest as clutch slip or crunchy/stubborn shifts.

Also the thump when going into 1st gear from a stop is normal. The input shaft of the transmission is still spinning, and when you engage 1st gear (when the car is static) the synchro rings force this shaft to come to a sudden stop when it engages.
