Wet handling number is very bad: 1.36,6 (about 7s slower than regular GT3, they say the tires behave differently... which also explains most of the track performance in the dry Smiley)

Were they cup N1 s ? Smiley

 Yes Smiley Front tires are a bit wider in case of the GT3 RS (245) compared to the regular GT3 (235).
