Having just done a track day at NCM in my ‘23 with iron brakes, I feel like the main thing holding me back is outright cornering grip. So many corners, I was having to hold back to avoid shredding the front PS4Ss. I didn’t feel like the chassis was a problem—with the track alignment, the car was playful yet predictable, as opposed to with the stock alignment where it seems to tend towards understeer and not have much interest in rotating on demand.
To be fair, my skill level and knowledge of the track (this was my first time there) were also holding me back, but I’m confident that grippier tires would have shaved a tiny but not insignificant bit from my lap times.
Also, I owe something like $60k on my 2023. I can’t justify multiplying that by 2.5, adding 2 years to my loan, and at least several hundred dollars to my monthly payment, in order to drop a couple seconds from the lap times.
I do regret the iron brakes, but only from a dust standpoint—they held up to NCM just fine. I found a vendor that makes custom CCBs and is getting me a set with pads for $7500 shipped.
Here’s my last and best session at NCM. Following a Porsche 997 early on. Skip ahead to 26 minutes to see me tailing a 911 Turbo S and a Cayman GTS for multiple laps.
