The 35 profile don't look perfect although I found out a few years ago that size perfectly corrects the standard speedo reading (they're usually 5% out)
Do they supply 275 section in 30 profile? If so, wouldn't those work?
I've been told by GT3 drivers that the Cup 2 is an improvement but I wonder if they mean over the Cup+, which is crap.
I will stay with Cups. Well enough proven, the only tyre for the CSL.
