18inch & a drop, would car bottom out?

I have 18X9.5 on a 96. Also have a 1.25 drop. No bottoming out.

1.3" on a 98 vert. I live in Buffalo and haven't bottomed out yet (crossed fingers). Our roads suck big time, and know where to just take it easy or go into slolom mode to avoid the bottomless pot holes.

Rims will make no difference in ride height provided you go with the recommended tire size for the size you put on, but those rims are going to slow down your acceleration quite a bit.
