Hello!

My name is Mike Carpenter and for the last couple months I've been building a 2009 MT 370z for competition in SCCA Solo STR Class. In this thread I'll post progress, lessons learned, and results from events I attend.

Just like any race build, things take time. From what I've seen, with the exception of Stock Class builds, there's really no data available in regards to STR or SP prep for the 370z. The goal of this thread is to fix that. Hopefully, you folks will find my posts helpful.

CURRENT SETUP

Suspension:
BC Racing ER Coilovers / Custom Valving BC NA
14k Front / 12k Rear
Whiteline Front Sway Bar Full Stiff
Whiteline Rear Sway Bar Full Soft
SPL Front Endlinks
SPC Front Camber Arms
SPC Rear Lower Camber Arms

Alignment:
-3.3 degrees front / ".25" Toe Out
-2.6 degrees rear / ".25" Toe In

Drivetrain:
Cusco RS Differential / 60% Lock
Whiteline Rear Differential Bushings
Redline MT Transmission Fluid
Royal Purple 75w140 Rear Differential Fluid

Engine:
Berk HFC Cats
3" Custom Single Exhaust (Saved 35lbs over stock exhaust)
4lb Shorai Lithium Battery

Interior:
Recaro SPG Seats
Bride FO Rails (rails are too heavy... but these are the only option with sliders that will fit me at this point... Total weight with seat is 35lbs. STR minimum is 25lbs. I could potentially save 10lbs a seat!)

Wheels:
TSW Nurburgring 18x9 +35 18.3lbs
Mustang Cobra R 18x9 +25 26lbs....

Tires:
Federal RSR?? (Probably switching to Yokohama ADO8R's for next year).

Current Curb Weight = 3134 with 1/2 tank of gas.
