best cars for cheap/realistic drift-missile builds are E36 M3, toyobarus, FC3S RX-7, mk3 supra, any MX5, and the good ol' memecars 240 and 86. I find the Zs to be too heavy (don't really like the ol "forza weight reduction", **** is that -600 lbs bull****? what are we removing, the chassis?)
turbo k20 swapping the 86 is one of my favorite drift builds. VtEc yO
can't go wrong with any 2JZ drift build either as long as you're not pushing 900+ HP in a 2400 lb BRZ like every forza player ever
