DiRT Rally 2.0

Go to free play custom event and select Jamsa Finland, vehicle class group A. Now select the stage Paskuri daytime to make it easier. Start the event and select the Subaru Legacy RS.
Before you start the stage be sure to take a spare tire in case you get a puncture, and in tune vehicle and springs set the ride height to maximum high front and rear and max firm spring rate. I would also recommend making the final drive ratio long in gearing as this stage is fast.
Around half way through the first split you will see a blue bridge and co driver will call 6 left past house. On the right after you will see it turn into a bank/small hill. Drive into it at high speed and an angle. As the centre of gravity is high and there is no give in the suspension you should quite easily find you start rolling. Once you have rolled at least 3 times drag what’s left of the car to the finish line and the achievement will unlock.

It’s only 5 gamer score but it’s a very rare achievement. Hope this helped and good luck!
