I also have a G35 6 speed coupe. The original rear tires are at the tread wear indicators. Would you reccomend I get another set of the Pilot Sport or is there another brand with similar performance I should look into?

 

If you are only going to replace the rear tires I would go with the Pilot Sport. If you are looking for improved performance take a look at the Bridgestone S03. In our testing they were better handling in both wet and dry.
If you are looking for a longer wearing tire at a good price take a look at the Yoko ES100.
If I can help let me know.
Thank you
