That same day as my new personal best, I developed an oil leak in the OE oil cooler. The Pfadt headers run close to the oil cooler and I think the sustained high heat of the track compromised the cooler. I looked up the cooler and they are made by Dana which is a Tier 1 supplier to the OEMs.

Dana uses a proprietary method to fuse the stacks together. It is a cold solder process. I believe the high heat from the headers was causing the stacked plates to separate from the mounting plate. It developed a crack right at the solder joint and the oil started to leak out. It dripped down onto my driver side header. Fortunately I saw the smoke and the oil did not catch fire. I made a deflector shield from some plastic in my tool box and I was able to make the 100 mile drive home. It did make a mess under the car and the rear bumper and trunk lid had oil all over them.
I bought and installed another cooler hoping it was just a defect since I did make it thru 3 or 4 track days since the header install. But at the next track day at the end of August, the new cooler started leaking. GM did replace that cooler since it was within their new parts warranty period.
I then bought a Mishimoto cooler for the Gen 5 Camaros. It's a nice kit but the sandwich adapter at the oil filter is quite thick. This pushed the oil filter down below the subframe crossmember. I have the ZL1 belly pan and that will help protect the oil filter. I am going to look for a shorter oil filter too.
