HOW MUCH FASTER ARE THEY? Yokohama AD08R Vs Yokohama A050

Lap comparison between two of Yokohamas flagship tyres.
The AD08R and A050. Clearly the A050 is a much faster tyre being a proper race tyre verses the AD08R which is a performance street tyre, and the difference on track really showed.
Both sets of tyres were 245/45R17. The A050s were medium compound.
Both laps are the fastest laps I managed to achieve on each tyre but were on different days.
Towards the end of the AD08R's life, times had dropped about 1.5 - 2 seconds. The tyres never wore out but did blister and go hard through heat cycles and constantly got slower.
The A050's stayed fairly fast throughout there life. I managed to equal the quickest time I'd done even after several track days. They did wear out completely with no tread depth left by the end.
