This happened a couple weeks ago, but I figured I'd put it up for the record. I was on the I-5 around 11PM in the middle of CA heading to SoCal. For those of you who've never traveled the I-5, it's just a long stretch of 2 lanes (in each direction).
Anyway, I wasn't really looking to race, but I think the guy in the M3 was bored, and was trying to get me to go. As we were getting through traffic, he was directly behind me, and we came to a clearing. I changed lanes to let him pull up to me and then go, but he floored it as soon as I started to change lanes. So he flew past me and then E-flashed me! lol
So after I came up to him again, and this time we were dead even when we started. We were going about 80, I dropped it to 4th and pulled about between 1/2-1 car length off the bat. He closed the distance by the time we were around 125, and pulled maybe 1/2 car length as we closed 140.
I didn't know his specs at the time, but when I came home and looked them up, it totally made sense. I was able to take him in the low end, while he ran me out at the top end.
My previous car peaked at very high rpm, so it was always paramount to shift as close to redline as possible. And, this was my tactic in the STi.
After that race, it felt to me as though I should've been shifting at 6500? When racing like this, where do you all shift?
