Hi enthusiasts!

I am about to widen my NA wheels inwards from the 9" stock to the widest possible.
does anyone have the possibility to measure how much space I have until I will touch any of the suspension parts..? It is like so much snow here so it is difficult to raise the car and check. I have put my hand in and it feels like I have about 5 cm before the rim will hit something. Going from 9" to 11" inwards is 5 cm ...
