How to unlock the Speed Master achievement in Need For Speed ProStreet - Definitive Guide
If you don't want to follow the method provided by N0RVY.
You should be able to get this and the other "master" achievements as you play through the career normally. You need to get 10 track records in the particular class to unlock each.
You can also work towards the "Ryo's Record's" achievements at the same time if you wish.
Cheap Trick
If you find you are strugling, or you want to get them out of the way early on, the track records do not need to be done on seperate tracks, so you can get it cheaply by only just beating the track record score, then re-racing the same race and beating you previous score slightly, then repeating the process until you can do no better or the achievement pops.
