Can you tell my how they fit under Integra Type R 1999?

Do I need do roll my finders and buy camber kit to let them fit without rubbing?

Post pictures if you have some

 

You will need to roll, and depending on tire size, you will rub. Camber kit isn't needed if you're low enough, but if not, it's going to look funny.

 

They don't really "fit" without a fair amount of work.

And to answer your second question, in short... yes, you would need a camber kit and your fenders/quarter panels rolled to clear those wheels with properly sized tires.

 

If you are looking for the "concave face" on the grid's, they will have to be 9 inches wide or bigger too. I know that's what got my attention on the grid's, till i figured out I can't even get close to a 9inch wide wheel.

 

widest we can guarantee is 16x7.5 @ ET38, so you're outside the comfort range to be sure....as mentioned both a camber kit and fender roll/pull would be expected

 

Here is a picture of a 16x8 +20 with a 205/40/16 on a 4 door. Not my car, and I will take down at owners request. But please DO NOT kill a ITR like that. Get yourself a good 16x7 or 16x7.5 +30, +35.
