MSR Houston is my home track too.

I could also take you out as a passenger too if you want but my CCW lap times in the past have been slower than CW so far.
My personal best at MSR Houston CW in my manual SS 1LE with 3Rs on ZLE wheels is 1:42.17 from a few years back on a cool day with stock brakes. (I don't recommend stock pads for 3Rs...I could smell them overheating and was doing cool down laps because of that. I still had the stock ABS module (EBCM) which was holding me back because I had to brake earlier (and lighter initially) to avoid "ice mode" sending me off into the grass. I figured a 1:40.9 was possible with perfect weather/driving and the 2019+ ABS module that I've installed since then on 3Rs after looking at PDR data/video in Cosworth Toolbox but I haven't had the chance to try yet; maybe this fall/winter on a cool day. Also the track felt more bumpy to me last year so it might not be possible to go that fast anymore.
It is interesting to read that 3Rs grip better when new as the grip is already excellent in my experience when used but I've only ever driven on takeoff sets that already had some street mileage on them.
I was going to upgrade to ZL1 brakes but changed my mind and just got track pads for the stock brakes in case I go to 18" wheels in the future to run takeoff slicks because the ZL1 caliper clearance is reportedly very small with 18s.
If you have PDR, we can exchange videos/data through private messages on here to compare our laps if you want!
These are the 220tw Supercar 3 PB laps I already have uploaded to YouTube. This was the only set of brand new tires I've ever bought for the car; I think it was the 3rd track heat cycle for these tires (plus a few hundred street miles) if I remember correctly:

I have actually already watched your videos several times. I am a member at MSR Houston, so if you ever want to come out, let me know. I would come out on the 12-13th, but I'm going camping with my family. I will probably be out there sometime next week if you are available. I will DM you my number
I have a few videos on YouTube as well, but only my first track day with the SS 1LE when it was 100% stock.
