How to unlock the Mechanic achievement in Riptide GP: Renegade - Definitive Guide
Just grind the first races over and over for $1,000 per win, plus the money you get from leveling up, which increases by $500 per level. At the final post-race screen you can hit to do the race over again. This is a great way to earn money and XP quickly since you save some time in the menus.
Hydrojets are unlocked as you progress through the game and beat the different bosses. Each hydrojet has four parameters which you can upgrade: acceleration, top speed, handling and boost. You can choose to upgrade the first one if you want to. However, you must fully upgrade the best hydrojet in order to be able to get three stars in the last events so there is no reason to worry about this trophy.
All you have to do is upgrade one out of the nine hydrojets to the max with the cash you earn from winning the events. There are four things to upgrade acceleration, top speed, handling and boost. You do have to upgrade the last hydrojet in order to get three stars so you will get it soon or later.
