It’s been a hot minute but the car is down to 2815lbs … and it might be a little lighter than that but the game continues…

Probably the greddy twin kit and went to the custom front mount. Went from 20ft to 25ft of stainless steel & aluminum headers/downpipes/Ypipe/midpipe/muffler to a crazy header and about 2ft of 4” stainless. Charge pipe setup was drastically reduced. Probably a net zero gain on turbo weight, Greddy’s intercooler was relatively heavy compared to the treadston 1245 and I went from that pretty large C&R Racing radiator to a much smaller unit.

finally pulled the trigger on a dry carbon hatch and found a set of (used) fiberglass/cf doors.

Also fell in love with a set of V1 Track Wheels … still cant believe how much I like them

Nice- any idea of what static weight balance is for your Z currently?

Not 100% but with the lighter turbo setup (although it's sitting in front of the engine) I moved the battery, radiator, and water meth to the hatch ... I need to find some corner scales
