This was our first race in GT-1 trim. While there is still some work to do, mostly around weight reduction and engine prep, this was a good opportunity to get out there.
We took 1st place in Saturday championship race, and 2nd on Sunday. Special thanks to Jon of Viper Parts Rack for helping out with replacement hardware on Saturday.
Reviewing the data from the weekend, I was surprised how much difference 2 piece rotor design makes, when it comes to managing on track temps. We had RB Performance’s newer design hat and open slot rotor on the left side, and Brembo ACR-X hat with older, traditional slot ring on the right. You can see the difference extra airflow through RB hat and rotor makes. Temperatures are in C! :dropdev:
Right side rotor cracked at the end of the race…
We were testing water injection for cooling the brakes, and while it had some effect, it was not quite enough to control the temperatures, next step is increasing the flow.

On Sunday we ran with identical setups left-right, and it was a lot closer side-to-side, confirming that the differences from previous day are due to rotor configuration, rather than track-specific conditions.
Anyhow, fun weekend. Some minor car-to-car contact, but the car has proven to be very resilient to taking bumps 🙂
