I wish I had kept track of it! I did not, but lesson learned. I'm writing heat cycles in grease pen on the sidewalls of the ECFs (which is currently only one from a break-in cycle). I think I maybe got 5 days on the trofeos, but I honestly don't know.

So I was doing some experimenting. On the windshield is my iPhone running TrackAddict Pro. It's capturing the footage that you see after the transition. It's capturing data from the OBDII port via a bluetooth device, but the update rate feels pretty slow. GPS data is pretty poor as well. As far...

Hot and hotter! I don't remember exactly but I think cylinder head >270 and same for oil. Next time I'm out I'll be paying much closer attention, because the car was pulling major timing for the final lap or so of my sessions. I did the two day at Charlotte as well. I've been to several racing...

Do you know what the difference in volume is? I may need better cooling if the GT4 program's radiator shroud modification doesn't produce meaningful temperature differences. From your testing, have you collected any data on differences in temperatures?

How does your unit compare to the one that comes on the Dark Horse?

Hi everyone! I'm trying my hand at capturing and editing some more interesting track footage. This is some old footage from October, but I had two in-cabin views and thought I'd give it a shot. I've never edited a video in my life, so this is pretty terrible, but nonetheless it was a great time...

I have about -2.8 if I recall correctly. My toe is completely neutral in the front and just a smidge of toe in in the rear. I just keep it that way all the time; the car isn’t my daily. I’m shredding my tires up in track and they die from heat cycling before I lose enough tread to make them useless.

100% - I’m relying on the naked eye here, so definitely not scientific.

Yes, still have them. I don’t intend to replace any of them until I can feel something off or the wheel/tire combinations fail to balance out with standard tape weights. I would love to verify, maybe I’ll buy the appropriate instrumentation and give it a shot the next time I have the car jacked up.

@Apex Wheels are you guys seeing any confirmed 18” fitments or interested in testing for such a fitment?

I suspect not as my car is configured. However, I think with a little more camber and the right suspension components, maybe? I know with -2.5 deg front camber an 11” wide wheel will fit with appropriate offsets/spacers. I agree - would love to be able to go with 18” wheels. Tires for 19s are a...

This was super educational!

Based on watching the balancer rotating said wheels. It would be nice to watch them on another machine but so far that’s all I’ve got.

I had this exact same thought - I was watching this video from Vorshlag the other day that went over that. None that I felt. I think 4 full days and ~3000 road miles. So probably 12-16 heat cycles? I did find that in my last two sessions, which were at about 85 degrees F ambient at...

Good morning everyone. I finally killed off the Pirelli Trofeo RS 180 TW tires that came on my car. 1 heat cycle too many - the center tread delaminated on one of them. So I went to get the tires unmounted and put PS4s tires on the OEM handling package wheels. I found that 3 out of 4 were...

That’s interesting. I haven’t actually measured, but I definitely feel like the PS4S sidewall is softer, so maybe that’s partially just from compression. I’ll typically run the PS4S at 36-38 PSI hot, but the Trofeo RS I’ll run at 32 psi hot. For what they are, the PS4S feel great. They’re...

I was using a square Conti extreme contact setup, but upgraded to wider Michelin PS4S setup. I use them for street, autocross, and wet track.

The Trofeo RS tires are absolutely out of this world. They say 180 TW but they drive like a slick. Mine live in the garage and only come out for track days.

Why is it that a naturally aspirated engine doesn’t have any caught oil on the driver side?
