Will this work for rear on a narrow body 996?

By my calculations it would stick out about and inch more than stock 18" x 10" with 65mm offset (26.7mm to be exact). Probably too much What do you think?

 

Employ this tool.

I have 19" x 11" rims with ET60 on my 996 C2 2002. That is the absolute minimum ET you need with a rim that wide. You have 18" rims but I cannot see that would make any difference. I would say that the rims will not fit your car.

They will stick out a little with that offset (6mm more narrow than turbo wheels). If you lower the car, they will tuck under the fenders.

 

I ended up with Victor Innsbruck in 18 x 10.5 w/55mm offset as I felt the 11" stuck out too far.

 

the lower the number the wider hence 51 sounds like a wide body fitment,factory fitment for narrow body carerra is 18 inch x 10 wheel with a 65et.although i believe gt3 is slightly diff.
