Can i drop a 19x9.5 inch wheel on front? What tire size is good for a 9.5 wide wheel? What about a 11" wide wheel on back? will there be any problems with rubbing or would i have to modify anything?

 

I know you can run a 17x11 in the front if you grind the knuckle off the front spindle. I have also seen 18x10s run up front so I would bet a 19x9.5 would fit.

 

19x9.5 in the front is "definetly" doable !
with the correct offset/backspacing

I am running 19x9.5's with 7 inches of backspacing on the front of my 1995 Z28 with 275/30ZR19 tires, also with Eibach "sportline" 2 inch drop springs, not a problem at all !!!!

I am also running 20x10's on the rear with 7 3/8's inches of backspacing with 285/30ZR20 tires.

20x10.5 on all 4 here

Offset / backspacing is CRITICAL like Chucky said

 

Whoa, you got new rims Paul? I can't wait to see/hear it this spring.
