SCCA STR 370z Progress Thread.... It can be done!

[MIKE_STR]

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.
