GT86 improvement build

Hi drifters I made a drift build on a gt86 an I know it needs some improvement to it so could I get some suggestions from some people the build is called improvment build it has 607hp

may want to drop the 7 horsepower out of it. i believe the cap for the production drift lobby (sorry not sure if thats what its actually called is 600hp. will open yourself up to more options with it and the ability to download if you dont restrict it from that category.
