"im sure people will complain about the caster been too low 3.4 degree and ffb is too light, and i dont have other choice cuz all info ive added to the car suspension and values are from irl manual ae86. and i like to keep things realistic"
I love that statement and the full stock 86.
TBH low caster isn't the problem if someone drive smooth and don't rely on self align torque (I mean hold and steer urself instead of leting it go like drifters do). There's a hot rot (T-Bucket) with 1° caster and I was able to slide it without problem.
If piece of crap driver like me can do it so everyone should be able to do without complain. For me it's just fun thing to drive challenging cars.
