First time ever on this track. Definitely sloppy run, getting used to new power band on lower boost still. Will have new coilovers installed before next track weekend.

Lol and launch control is still set to low for the turbo size.

Fun weekend with many highs and lows at Blackhawk Farms Raceway!

Lots of highs and lows shaking down these two cars. Long way to go to have them completely ready.

But very proud of the team! The JM RSTI went on track on Friday for nearly 8 track sessions. Then Saturday another 4 more in the morning and standing start in the afternoon! The amount of abuse this car withstood is a statement to progress and quality.

The JM 24 WRX on the other hand had some cooling issues and will be back to the drawing board! After new ARP head studs and upgraded radiator the airflow just was not there. With the large intercooler and oil cooler we are needing some hood vents to allow more airflow. So this hood will be getting cut up and prepared for our next event for more testing!

Will post a few videos tomorrow.
