2 totally different things dude - why not get both ? hydro e brake is sick for 100+ km drifting, and a line lock is for burnouts and such, dropping the clutch at 8000 rpm and hoping on the brake isn’t great for the car , it holds fluid in the front brakes locking them so you don’t have to, and its easy to install on our cars too - it makes it a lot easier to do 2nd and 3rd gear burnouts if you choose to do so lol
