You will physically have to measure your discs to get the correct answer.

Spare parts systems will say 280mm with 15" wheels, 300mm for 16" wheels.

My i30 came with 16" wheels and 280mm discs  :crazy1:

Have you tried searching on www.partsouq.com (http://www.partsouq.com) using vehicle VIN number? This will provide the OEM part number, and if you search using that number you should plenty of links to alternative parts which would tell you what the diameter is. Failing that, take the wheel off and measure it. I thought the bigger discs were for the versions with higher power engines. My 2015 1.6 diesel has 15" wheels and the 280mm discs but I think I read somewhere that at some point Hyundai started using the 300mm discs on all models and it was not possible to have 15" wheels because they wouldn't fit over the larger caliper.

According to hyundai, my 16 inch wheels have 280mm discs.
