Aside from everything others have said (and I've done too
) the biggest three things I've found (either through driving myself or watching others on track) that have gained me time over my almost 3? years here, especially in the MX5 are, earlier braking points (125M vs 100M), higher gears in turns (3rd vs 2nd) and just plain keeping it on track all race.
- Earlier braking points - better car balance, better turn in speed = better exit speeds (the close driving in our races here helped me learn this a lot)
- High gears in turns - with earlier braking points you carry more speed without upsetting the car balance, and gives you more push out of the turn. Like riding a bike, if you can keep the speed up, a higher gear will give you more power to the wheels. But only if you can keep it above X speed. If you dip below that speed, then a higher gear will be hard to peddle and you will slow your overall speed until you're back up to speed.
- Keeping it on track - 1 very fast lap is easily negated by a second lap with an off. Plus, the way I look at it, the more I'm on track racing consitently, the more the drivers in front of me have to be on track consitantly if they want to hold the position.
Set up wise, I don't do too much to the Mazda. For the last year, no matter the track, I'm running a 3 front ABR and a 0 rear ABR in the MX5. I up the camber a lot too (and correct tire pressures), but if I could only make 1 set up change it would be softening the rear abr. Previous to the that, I didn't really find my "groove" with the mazda (a 0 rear abr gives me the slow catchable swing in the rear I like with the mazda). But like I said, i use this for every track, so not all set ups are to make the car fast, they're also there to make you feel confident in the car, which in turn makes you fast.
I also always practice with 22L in the Mazda (full tank for our races). That way when it's time to race I know how a "heavy" fuel load handles, and when I go for a fast lap in quali, I'm giving myself an extra mental confidence boost beacuse I "know" a car with lighter fuel should be faster. So if I can do X time with 22L, I can do a faster time with 8L just by doing the exact same lap I did with 22L.
TLDR: Slow is smooth, smooth is fast. Can't compete if you don't stay on track
As for the racing yesterday, finally had an awesome 20min scrap with Han that didn't make me want to pull my hair out or punt his arbath off into the dirt
