Yes. The hard compounds get grippy like regular tires after a warm up period. In our case, 2-3 laps. You will see folks swerving in the out laps to try to heat tire.
I don’t know that I’ve ever overheated a rental tire. Once the grip comes in it stays the same throughout the race. Dont feel drop-off.
Nice track and nice quality rentals. I do a fair bit of rental racing. The rental karts can get a nasty hop that appears to be weight related. It seems that if you ask too much of the kart in terms of how much you load up the kart laterally, there’s a breaking point. The kart then violently hops mid turn. Can be severe (I hurt myself, once).
So, for the corner in question, I rounded the entry and made the braking less late. Hop goes away.
