Will these fit on a narrow body 996? 19 x 8.5 front and 19 x 11 rear

FRONT: Offset: 53mm, Backspacing: 6.92", Bolt Pattern: 5-130, Rec. Tire Size:235/35-19, Weight: 23.0lbs.

REAR: OFFSET: 60mm Backspacing: 8.39", Bolt Pattern: 5-130, Rec. Tire Size:295/30-19, Weight: 24.4lbs. These wheels came off an 09 911S

 

That's the same setup I run on my narrowbody...with a 14mm spacer on the front.

 

Check out this site

http://www.1010tires.com/WheelOffsetCalculator.asp

It is an offset calculator which will show you how much the wheels will move in or out relative to your current wheels. The other variable in the equation is the size of the tire you run. If you look at Fly996's pictures, particularly the rear wheels you can see how close the wheels/tires are to the body. You don't wnat them to rub/hit the body.

You can also roll hte fenders/lips, which I did on my car to get more clearance. Here is the site where I rented the equipment to roll my fenders

also, what year is your car? I think the 02+ have a little more room on the rear...
