I have a question to ask on a related topic.
When peformance driving, is there a general RPM which, once you drop below, you downshift so as to remain on power? IE, Revs drop below 4.5k you downshift. Drop below 5k. Etc.
I ask because I put myself in a dangerous situation, both mechanically and mortally, by under revving on a downshift when going around a corner.
The situation: Navigating a diminishing radius corner, third gear but decelerating gradually as the corner got tighter. Next their comes a pretty sharp kink--I was going around 50-55, can't be sure. Revs at/around five. I go for it, initiating a quick heel/toe which I didn't match properly. Think I needed to hit near 6.5 or so, which I didn't. Don't know how much I missed by, but the rears locked as I was turning in (still on the sweeping part) and as a result my rear kicked out alarmingly quick. Thankfully I caught it. Dangerous situation I put myself in; my nose was angled directly toward the ditch. Desolate road so there were no oncoming cars ( I could see through corner.)
Anyways, haven't driven that hard since then, which was a couple weeks ago, nor have I returned to that road.
So you downshift when you dip below what RPMs when performance driving? I'd like to find out if there is a sweet spot most people adhere to.
