Exclusive Autosport driver Foster qualified third for race one, but the qualifying session for race two the next day caused drama after electrical gremlins meant a difficulty shifting gears and Foster could only qualify 12th.
More importantly, the issue came less than five hours before it needed to be ready for race one, so the Exclusive crew had to strip the car in record speed to diagnose the issue and repair it.
Foster knew he needed big points in that race to negate the loss of points he’d likely suffer in race two starting so far back.
Foster capitalised early in race one as the two cars ahead of him went off on the greasy track after rain drops, but Foster showed no sign of being caught out and took the lead.
Despite a caution bunching the field up just after, Foster jumped into a huge lead and would not be usurped to take his third win of the season, following victories at the Lucas Oil oval and the Indianapolis Motor Speedway road course.
“The issue with the car was an electrical problem which is one of the most difficult things to fix, especially quickly,” Foster explained.
“It stopped me from shifting gears.
“If it was mechanical, we’d just be able to change the gearbox, simple. With it being electrical it could have been so many different things.
“We spent a bit of time looking at data trying to pin down exactly what it was and we figured it out.
“Can’t thank Exclusive Autosport enough for that because I would have started P3 and would have just fallen back without being able to shift if they hadn’t repaired it.
“Without them putting the hard work in between the sessions, pulling the car apart and trying to figure it out, we wouldn’t have had that win.”
In race two, Foster initially moved forward from his starting spot to eighth but lost a handful of places avoiding a car while attempting an overtake, and finished 12th.
It means his championship lead is now 19 points after 10 of 18 races.
“I’ve tested here twice before, and to be honest I was sceptical as to how good our pace would be,” Foster said.
“This definitely isn’t our fastest track still, other tracks we’ve had a bit more pace than this. Definitely has been one of our weaker tracks so far this season.
“To come away with a win and to rebound from a tough issue at a track that isn’t our strongest is definitely really good. It just shows how strong we can be at future tracks.”
Next up for Foster and the Indy Pro 2000 series is the Mid-Ohio race - another permanent road course - at the end of the month.
