Love teh phots Grant. Silver suits that car!
I get 4-5 days from Cup2s. 5 days would be an absolute max. Often I change them after 4. They are heat cycled before the end of day 3. I do around 60-70 laps a day. 5-6 x 15-20 min sessions.
From many years of using the Cup2 on three gens of GT3 and collecting AIM data Ive come to conclusion they fall off after 14-18 heat cycles.
My observations on track with guys I know who had the car delivered on the Goodyears is those tyres last longer but are fractionally slower. The lap time delta is so small I think it warrants the longer life/lower cost.
Cup2 for 992 GT3 getting expensive in our market now. Around 2000 USD a set so 4-500 USD a day.
Just my opinions from personal experience.
