The subject line says it all. This will be the 430's first track day and my first time on track in a street car (all track experience to date in the Skip Barber formula cars). A few questions: Should I mount some more track-focused tires for the event? I'm currently running a set of Michelin Pilot Sport 4S tires with about 800 miles on them. If I use the 4S tires, should I expect them to be trash after the session and plan to replace them directly? Is it worth switching to track-optimized brake pads (steel rotors)? Is it worth switching to track-optimized brake fluid or simply flushing with more of the DOT4 usual? Is anyone else concerned about running at speed with only a street-config, 3-point inertial reel seatbelt or do folks just make a decision to accept the increased risk of not having a proper five or six point harness? I'm already going to feel exposed without my Hans... What else should I be considering?
