Downshifting?

[misterlance]

People who are afraid to downshift should get automatics to do it for them. Automatics downshift too you know.

I'll post pictures of my ORIGiNAL 270,000 mile clutch I pulled out, That has 10 years of accounted downshifting on it. Tranny still good. Guibos are fricken rubber and will go bad no matter what.

any idea what size nuts and washers and bolts u need to make these clutch stops??

How often do you guys miss shifts? I do it maybe once every 6months to a year, and thats if I'm distracted and its just kind of a "Doh!" moment.

I find that to be more than a "Doh" moment, that's a OMG STFU $*%)%) moment.

Why is it that so many of you cant downshift properly, or can't revmatch?

I can understand that not everyone can go totally clutchless, but downshifting and revmatching are pretty basic driving. I was doing these things about a week after I learned to drive, everyone is making like its a big deal or something.

I guess if your that good, never miss a shift, then I say go for it.
But for the average daily driver practicing enough to get that good
might cost a tranny, guibo, motor mounts etc.
IMO I would rather do 2 complete brake jobs than replace a tranny, etc.

even with the autobox.

I do not agree. Every car shifts a little different so there is a learning period. Any small grinds, mis-shifts cause unnessasary wear on the tranny, down-shifting also puts extra strain on motor mounts, driveline bearings, bushings etc. All of these parts including clutch and tranny are more $ and more work. Brakes are one of the easiest and cheapest repairs, besides you can not stop without using the brakes so why wear everything else out to?
Popping out of gear is a common result of speed shifting/rev-matching.
It is also a good way to get rearended.
My clutch stop IMO best bang for buck mod.
$.33 carriage bolt
$.18 nut
$.08 lockwasher
From ace hardware, took less than 5 min. to install.

well apparently from the other posters, you can save the brakes and such if you just downshift correctly if you dont do it right though then the damage comes in, but if you are good then there should be virtually no wear on any engin/tranny related parts. plus you save brakes. using the brakes from rolling at 10 mph to 0 is a lot less usage then if you slow down from 45 mph to 0

I rev match gears a lot of the time in the e30. For a long time I did it every shift because I wanted to improve my technique, i don't even have to think about it now. In the race car often times I wont even use the clutch, i've gotten smooth enough we don't have any problems with breakage or wear. Often times the weak point in the drivetrain of a high output car is the clutch, so we stay off it. I use engine braking around town ALL the time cuz it save brakes, clutch, drivetrain.

sounds good.

im thinking about getting a clutch stop, sounds worth it...i just want to make sure i properly install it

make your own

x1 50 cent bolt
x2 25 cent nuts
x1 rubber boot from a chair (I got a 4 pack for $2.00)

then all you need to do is cut a slit in the carpet where the clutch stop threads in, and set the height for just after the point where the clutch disengages. simple and cheap..
