The Grip and Corner's flutteriness suited me.
I used it in Tsukuba Circuit only, but it didn't slide at all at lap time 8 seconds, but it started to spin after about 4 hours.
The reduction in the Edge section was limited.
The Center was a BALI mountain, with some Mustache left in place.
It could still be used on the road in general.
It was an exchange from α13 and I felt the fluttering was much better.
I feel like the deceleration is shorter too.
Maybe it's depleting faster than SUPERCORSA? I...
