Nah its like when the find the "biting point" in clutch control it can squeek when you let the clutch out.
When i bought the car it said it had an uprated clutch but maybe because its an advance it has an LSD? any way of checking without taking it all apart lol
you mean too check for a lsd ? jack one wheel up off of the floor and try turning it .
or jack both sides of the car up and turn one front wheel . if the opposite wheels turns in the opposite direction of which your turning it , it has no lsd if they both turn the same way it has a lsd .
LSD's were an option throughout the Starlet GT range.
