ok, I need some help understanding what happen.
It really has me confused, since I do not want to have it happen again.
The Basics
Tires -Falken AZENIS RT660 - 275/35 18
Wheels - ENKEI RPF1 18X10.5 +15
Tires were new as to start of the year.
Tires had 10 1/2 hours of track time
Trips to cleveland oh and Pittsburgh
Drive to the track on the tires, do not change
Alignment Before
Left Front Camber -2.6 / Caster 6.1 / Toe - 0.0
RIGHT Camber -2.6 / Caster 6.1 / Toe - 0.0
Front Total Toe 0 / Steer Ahead 0
Left Rear Camber -2.3 / Toe .03
Left Rear Camber -2.4 / Toe -.01
I have run this Alignment for 2 events before this one.
Check tires after each event, before this event everything looked ok
Tire pressures - always aim for when I come off the track F36/R34
so the starting pressure varies, from session to session
Front starting can be 31-32
rear starting can be 28-30
Last track day when this occurred last 2 sessions starting was
LF 31 RF 20 LR 29 RR 28
The new Alignment starting now:
Left Front Camber -2.2 / Caster 6.3 / Toe - .11
RIGHT Camber -2.1 / Caster 6.2 / Toe - 0.08
Front Total Toe .2 / Steer Ahead 0.01
Left Rear Camber -2.5 / Toe .06
Right Rear Camber -2.6 / Toe -.02
Rear Total Toe .08 / Thrust Angle 0.02
Going to stay with the current tire pressures.
