Default Aggressive downshifting

I'm curious to see what you guys are downshifting at on stock gearing ap1's for hard pulling, I usually do this, 30mph=1st, 50mph=2nd, 70mph=3rd. Can I make my downshifts more aggressive? (as in maybe 35mph for 1st) what's a good point without really pushing it? I don't want to downshift into redline and then have to shift up again. Anyone have any input?

Your question makes no sense whatsoever. Rephrase if you want it answered.

You just want to be right at 6k or slightly over if doing a pull. So downshift to what gets you there.

@woodson My question makes perfect sense to me and apperently to these guys as well. So please take your English teacher self somewhere else if your just going to question my grammar.

@s2000maniac are you serious or trolling? Is downshifting into first harmful? Even if kept within limits? For example downshifting into 1st at 30mph where it puts me right at 6k rpm's

I'm with Woodson, I have no idea what you are asking.

What do you mean by 'make your downshifts more aggressive'?
Also, the question makes perfect sense to you because you wrote it. I'm sure fellow members here are 'guessing at the question you want answered'.

Holy moly that is good to know, I've down shifted into first way too many times but it looks like I'll have to stop. Looks like 2nd gear is my new bestfriend now. And it all makes sense now, I've always noticed its extremely difficult to get into first gear when rolling.

And what I ment by making them "more aggressive" is downshifting at a slightly higher speed therefore when I downshift my rpm's will be higher therefore having a harder pull while in vtec. Does that make better sense? Idk maybe you guys are right and I'm just confusing lol

First is never meant to be down shifted into. The syncros have to spin that gear up something mean. Keep doing it and report back how your wanker driving has totalled the tranny.

If you are auto-Xing, it may require downshifting in to 1st. 1st gear has a very aggressive "blocker ring" which makes it more difficult to engage on a moving downshift from higher speeds. It can be done and it usually involves a double clutch and revving the bejesus out of it. If you downshift from about 40 mph in 2nd (which should be about the fastest you should attempt such a maneuver), you will be at redline when you're done and had better rev it up to redline before you drop the clutch or you'll chirp like a sick bird. At lower speeds, it is possible to downshift to 1st by just revving hard to match. It's possible to beat the blocker ring if done a certain way. However, unless you're on the track, why bother?
Use a gear calculator to know what each gear is good for in terms of road speed and rpm. And no, your first post made no sense. It wasn't till others added bits and pieces that the puzzle finally came together.
