I have internal and external temp sensors. Unfortunately, VBOX only allows 100 channels.

Thanks for the info on the Bridgestones. I’ve run them on my GR86 and am familiar with center wear. Now I know why it looked like that! I usually start very low (24/25) since I get the tires hot fast and don’t want to waste the first session. Will try to take it easy first few laps.

I'll be at COTA next weekend as well. Still have some life left on a set of SC3's from last year. They've been my favorite tire but since they're on backorder maybe I'll try the RE71RS once I'm ready for some 2023 tires.

Nice, would love to meet up. If you’re looking for a garage spot, we have space.

Appreciate the offer but I've got a spot lined up. Would be great to meet up. I'll be in the gentian blue cayman #111 that's just trying to point everyone by quickly. What car number are you?

i have one track weekend on mine and liked them very much. Much improved lap times over the r888r’s I was using when the Bridgestones were not available. Hope you like yours.

Wow. This is unnerving. Thanks for all the info. So 32-34 max hot pressure and bring them in slowly? The latter part just for the first few heat cycles on a new set of tires, or each and every session? Thanks!

More so don't abuse them when cold especially before a couple of heat cycles. 32/34 psi is minimum pressure not maximum.

Thanks for the clarification. I misunderstood. Any idea what target hot would be?
