Sorry, just my misunderstanding, front and rear drop are exchanged. Now I'm reading all your suggestions.

p.s ok, I've read, but I don't know why you suggest a wider front width, 0.5 or 1.0 at the moment doesn't matter, why wider?
A narrower front will give more steering and more reactivity, in all corners parts, so I moved into that direction.
I'll follow other suggestions but please help me to understand why a wider front. Thank you so much.
