threshold braking is just braking as hard as you can BEFORE ABS kicks in, so right at the threshold before the wheels lock up.

trail braking is just a term describing braking while you have steering still inputted into the car. example: as you begin to add steering while entering the turn you can 'trail' off the brakes to overlap your inputs rather than doing all your braking in a straight line, then turning the wheel to the APEX. Saves time and keeps some cars balanced better.

google will give you more info, but that is it in a nutsheel.

Nailed it. Be careful with trail braking though. While it can help balance a car out, it can also unbalance the car. I'm not saying NOT to do it, because it can be very helpful, but work your way into it in a safe environment.

Btw can we use clutch kick beside down shifting when entering a corner on mid speed say 120kmh?

A clutch kick would be used to upset the balance of the car intentionally. Useful sometimes I suppose, but unpredictable and hard on the drivetrain. Probably not something I'd suggest for a normal line, but it might help get you out of a bad line.

Trail braking can help rotate the car on the entry of the corner. Or it can take you into a spin pretty easily too. It definitely takes some practice to get it right, but it's pretty helpful on cars that have trouble rotating at low speeds.

I wouldnt recommend "clutch kicking" on the stock Evo drivetrain, that wont help with longevity Im sure. Learn the trail braking technique and you should be good

Adding to the discussion, Im a firm believer the Evo (when setup with an upgraded rear diff) is not a car that needs to be trail braked.

I want to be at > 0 acceleration (In other words, not decelerating in any way) at corner entry. So brake straight, use rear rebound settings to dial in corner entry rotation, and throttle through the corner.

It became abundantly clear when I put the torsen in the front of the talon that when decelerating the torsen increases understeer off throttle. Being at "Zero" acceleration (again, enough throttle to not accelerate or decelerate), the car had the best bite on turn in.
