Impulse buy: 2015 Fiesta ST

[D_Eclipse9916]

 The tires I'm running are the stock summer tires Fiestas came on which are a 140tw, but after 5 years they're not very sticky anymore.

First, congrats on the win.
Second, 140TW tires are illegal in STH (Mr complainer about non-legal cars )
Third, your driving is much better.  However you are diving too hard into a corner; plowing mid-apex out and slow to get back on throttle.  Hurting your exits as you are still trying to get the car turned while in what should be an acceleration zone.  Work on backing up your braking zones just a bit.  Then just keep working at it. You got potential to be a good autox driver with just more practice and a bit of coaching.
