I guess I'll share some of my 2019 PBs so far, which I think are quite decent for a street car and stock power. (no weight reduction)
Sonoma Raceway 1:51.59
Start at 1:51
Stock power, stock full fat weight, 275 square NT01, JRZ RS One 550/800 suspension, Rotora BBK w/PMU 999 pads, Dinan FCAB monoballs + front sway bar
Thunderhill East (bypass) 2:00.066
Start @ 15:18
Stock power, stock full fat weight, 275 square NT01, JRZ RS One 550/800 suspension, Rotora BBK w/PMU 999 pads, Dinan FCAB monoballs + front sway bar
Laguna Seca 1:42.39
Stock power, stock full fat weight, 275 square NT01, JRZ RS One 550/800 suspension, Rotora BBK w/PMU 999 pads, Dinan FCAB monoballs + front sway bar, replica GTS front lip + rear wing
Was less than a tenth of a second faster than prior PB that was without the GTS bits.
