Tänak: 'a win for my fans'
Toyota driver pleased to turn on the WRC style in his homeland
Like WRC counterparts Ott Tänak and Hayden Paddon, Breen used Estonia's high-speed gravel roads as a testing platform for the eighth round of the WRC.
The Irishman set three fastest stage times as he worked to perfect the balance and handling of his C3 WRC on roads that are similar to those he will face in Finland.
"It was a good weekend and we come away not only feeling very confident but also with some good data in the bank," the Citroën Total Abu Dhabi WRT driver said.
"We started well with a good set-up for Friday's shakedown and we gradually worked on that basic configuration to pick up pace as the rally progressed.
"I am very pleased with the work we achieved and I can’t wait to start fine-tuning the result when we begin our pre-Finland testing."
With Toyota rival Tänak setting the ultimate pace at the head of the field in Estonia, Breen looked odds-on to finish as runner-up heading into the final day of competition.
However, a 2m 10sec penalty for arriving late at a time control on Sunday morning dropped him to third place behind Paddon's Hyundai i20.
"Unfortunately, in the service the guys found a problem. They thought they'd rectified it and then with two or three minutes to go they realised it was still there so we had to change some parts on the turbo," Breen told WRC All Live’s Becs Williams.
"There was no stress about it. It was more a case of having the car in good working order for us to test."
Breen's fightback was then curtailed when he lost another chunk of time during an incident that he described as a "wake up call" on Sunday's opening test.
"It was a completely flat corner but I thought it was tighter than it actually was," he explained. "I got a bit of a fright. I turned the car more than I should have and spun.
"It was a very rookie mistake to be honest with you but we got away with it."
