I was looking through the cooking utensil drawer and found a thin, but rigid spatula that had a beveled edge:The model indicator "s" (yours will be "gts") badge was the most difficult. The word Kizashi was the most frustrating only because the letters are broken up instead of all attached like the word Suzuki. But for the most part I was able to use my finger to start an edge and then slowly pull the badge right off. It didn't even leave a residue. I did leave the car in the sun all day first however.

It took maybe two minutes, and the rubbery glue rolled up and off the paint just like the original post said.
