Some very good tips from truepiece etc on finding better lines.
But while hotlapping will certainly help gauge your progress, it will only help so much for achieving
race consistency - especially with combos like this one where there are so many ways to die.
So a few words about
race practice and pace may also be helpful since you are looking to race the combo:
First, a couple of questions. Are you using R2 front and rear in your replay? Any how many laps are you expecting for the upcoming race?
Reason I ask is - clearly your tires won't last for even a short race using the setup, tire type and/or driving technique you show in the replay. If you have R3 in front, then you will need a different setup or more importantly, better technique. The R3 should last indefinitely if your lines are smooth (which they aren't in the replay). For that matter, R2 fronts should also last with this combo with proper technique/setup (see below).
To get your tires to last, truepiece's advice on hitting the apex should help .... Another way to put it - "slow in, fast out". In your replay, your right front tire is over-heating from late braking and then having to overpower the exit (car slides more - heats outside tires). More on this below.
So - some tips on
practicing for a race:
1) I rarely do hot laps when practicing for a race. Especially when the hot lap setup is using a softer tire combo. Better to find a "groove" with your race setup/tires.
2) I practice starting with tires at the cooler starting temp that you will be faced with during a race. This way you will be familiar with the changes in feel as the tires warm during the race. If you drive smooth consistent lines, you should be able to see some improvement in each lap as the tires warm.
3) As you practice (with cool tires at the start) - find a pace that allows you to go many laps without major damage. In this case - at least 10 lap sessions. No point in being fast for a lap or 2 if you don't survive laps 3, 4, etc. As you find a "groove" in a session try increasing your pace somewhat - not by braking later, but by carrying a little more speed into a given turn.
4) Practicing with cool tires at the start also allows you to judge both how your setup and driving technique handle the tire heat over the duration of a race - so that you can adjust as necessary.
5) Be aware that your race pace will be well off your hotlap pace - especially if the race and hotlap setups use different tires. Do NOT try to match your hotlap pace in any case. Brake earlier - this emphasizes the "slow in, fast out" approach.
I'm no "alien" - but you may learn something from the replay attached. It's a 10 lap race in single player mode (with a pit stop). All 7 flying laps are between 1:10.50 and 1:10.70. That is most of a second off my hotlap time. I could thus turn faster laps but that would probably lead to sudden death or overheated tires :-/
I have also included the set (R2/R2) that I used in the replay. Like you, I generally don't like "hotlap" setups for race use - both because they are more ticklish to control and they general have more tire heat issues. You should find that this set is pretty "stable". "Aliens" will be able to turn even faster laps without overheating the front - I'm still working on that as a general thing for all combos - it's one way you know you're improving: faster times with less tire heating.
Hope you find this helpful
