It's a 1:07.977 for Chambliss...
Our second title contender Pete McLeod follows Chambliss...
The King of Qualifying 2017 could round off the season with another accolade this weekend but he'll need to make sure he's correctly eliminated some tactics after this session – he picks up a double helping of penalties in his second run – no doubt testing as he goes
It's a 1:06.489 for McLeod...
Juan Velarde of Spain flies next, with Sonka, Hall and Muroya left
As Velarde made it through to the Final 4 in Lausitz, he (along with the other Final 4 competitors) will only fly one run in FP3
The Spaniard posts a 1:06.887 including a 2s penalty for incorrect level at Gate 4
Championship favourite Sonka up now and it's his title to win here at the Indianapolis Motor Speedway... he has just this single run to refine any race lines ahead of Qualifying...
1:05.766 clean for Sonka... which leaves him in 6th with Hall and Muroya to fly
And now follows our back to form pilot Matt Hall!
1:04.401 for the Australian and that is serious fighting talk! Hall is eager to make up for lost time and will be looking to get a 3-2-1 to finish 2017
Last pilot in FP3 is Yoshi Muroya – Sonka's biggest rival for the title and a massive fan favourite back home in Japan...
1:06.367 for Muroya and that leaves him in 8th, a place behind Sonka
MASTER CLASS FP3 QUICK RESULTS:
Full story to follow shortly...
It's Challenger Cup Qualifying time! Who's ready?!
CHALLENGER CUP QUALIFYING STARTLIST:
Sweden's Ryfa flies first today and he's currently in second place behind Bergér in the overall standings and hoping for a win here
But that's the buzzer for incorrect level at Gate 8 and it's an automatic 2s added...
He sets the pace for the other five competitors with 1:21.408
Melanie Astles to go next... and while she can't win the overall title she could take a career first win if she plays it right today
She was down in 6th place in FP3 so there is a lot of work to do now if she wants to make good
She's into the track from the standing start at 121.1kts
It's green at the first split time and her lead grows by the second!
It's a 1:18.059 for Astles!
Next up is title favourite and 2016 champion Bergér...
Bergér is currently leading the standings with 36 points and is guaranteed the Challenger Cup with a win here in Indianapolis. And depending on the results of his opponents, the German could end up with the cup if he finished the race in second, third, fourth, fifth or even at the very bottom in sixth
The German pilot takes off and enters the track at 125.42kts, faster than Astles, which will help his cause
And he's green at the first split, but it's red by the second... and then it's red again
He's off the pace and it's red to the end... Bergér can't catch Astles! It's a 1:18.586 and he's in second, with three to fly
