But coming into a corner or such it just sounds bad *** when you go from 3rd to 2nd and rip it

I always down shifted through the gears with my manuals. You are going to go through a lot of brakes if you just push the clutch in and coast to a stop. Not to mention it's dangerous not to be in gear as you slow down. Now I've been driving a long time compared to a lot of you so maybe the kids now a days haven't been taught how to drive a manual properly

Not true. Put it in D and count as the gears shift all the way up to 7.

I don't see how its dangerous.

here they tell us to do it because it means you wont wear out your brakes but I honestly don't like doing it. I CAN do it but im just happy with clutch, second, brake and let go of the clutch for turning.

Cyberium · 04-05-2010, 07:11 PM

I'm not talking about long drawn out stops... i'm talking about quick stops where you can be in 4th gear and then just push in the clutch and the brake instead of downshifting. It's just common sense. I also do not agree with your statement saying it's dangerous to be in a higher gear when you stop opposed to being in a lower gear. If your in ANY gear and make a mistake you'll still lurch forward and stall.

Vegitto-kun · 04-05-2010, 07:12 PM

most of the time I tend to put the car in neutral if im just slowing down to a stop

NXTAZEE · 04-05-2010, 07:40 PM

If it's a sudden stop then obviously it's clutch in and stab the brakes. But a controlled stop should have you going through the gears. Here is an example; many years ago I was rear ended by a pick up truck while I was coming to a stop. I was slowing down but noticed the guy behind me was not. This all happened very quickly and if I had not been in the right gear it would have been much worse. When I noticed he wasn't stopping I quickly punched the throttle began to turn left on a side road. He still hit me but I was almost out of his way by then and had very little damage to my car. Had I been in a high gear there would have been no way I would have gotten out of his way and would have been sandwiched between him and the car in front of me. In that case I would have sustained injury and major vehicle damage. This is just one of many things over the years that experience has taught me that justifies having your vehicle in the right gear at all times.

Well if I am slowing down for a turn I always tend to go to second so. I should be fine if I have to slam the throttle

I wasn't planing on making a turn, I was able to because of the gear I was in. I was stopping at an intersection, the side road was just an option I had to avoid the accident. If you are in the right gear, or close to it, then you have options, other wise you may not.

Vegitto-kun · 04-05-2010, 09:52 PM

True. if I stop for an intersection I tend to still roll to it in second with the clutch pressed in and then shifting to first when im at a stop.

I'm in manual mode 99% of the time and drive it the same way I would a manual, changing down to slow or to bring it to a stop. Had my S15 which was a manual for over seven years 60,000 Km and never had to replace the break pads.

NXTAZEE · 04-05-2010, 11:53 PM

My last manual was a 03 VW Jetta GLI with over 75,000 km with original brakes.

You are right ZEE but do you see a difference in the rpm from manual to D mode? Seems like the D mode runs a little higher rpm!

I haven't paid that much attention to it. Next time I'm out on the highway I'll check it out.

D is always at the minimum of 1500 rpm when in gear most of time its in a gear I cant get into with M since its just at the limit
