Fun day out at Thunderhill. This car continues to survive through the continuous beatings I give it. Tires are still shit and the brakes are near impossible to modulate due to the lack of front grip. I made a change from dtc70 to dtc60 pads and it did help a little. Still need to change the front spring rate, still too stiff and getting bouncing behavior around turn2. Understeer is still very much a problem that needs to be solved, but will stay as is for now.
