NASCAR Heat Evolution

Don't be scared. I got both 100 percent race achievements in a single quick race. Chose Watkins Glen 90 laps All flags No damage. Starting at rear of grid, try and cause mayhem before 1st corner by spinning out other cars to bring out the caution. This will advance race 3 laps. Restart and do the same thing again and again, but dont cut any corners or you will incur a penalty. I pitted twice during the race just to be sure to have sufficient fuel and good tyres for the final dash. At lap 87 i restarted in 10th place. So with 3 laps to go it was pretty easy to pull ahead and keep a steady pace, winning the race and unlocking achievement, along with completing full race distance achievement. It took about 15-20 minutes.

It appears you have to win a 100% length race in Career mode for this achievement to unlock. I did a Quick Race at Talladega last night, and got the Complete a 100% length race achievement, and I won the race. But this achievement didn't pop.

I just ran a career mode race at Kansas, with a tune from Knee Pit Gaming located here: . I did alter it some as it was too loose for me in the pack.

It was far from a perfect race as I wrecked, from the AI's bumping me, too many times. But I still managed to win. This tune, with the right tweaks is at least 1 second a lap faster than the AI's on Normal difficulty.

Make sure you have your car most of the way upgraded. I have all Hp upgrades, and all but 3 total upgrades. Can be doable with a lesser car, but much easier with more upgrades.

I think the best track for this achievement is martinsville, by 100 % race length you drive on this track 500 rounds. Each round 21 seconds and with pit stops you drive 3 hours. The track is really easy.
