Been a lot of yrs since i did wheel alignments but
hunting to me has usually been a toe in/toe out issue , excessive of either ,in this case i agree with Sparky , some tow out to compensate for "pulling the car along between the wheels "
the other influence this yr is the salt condition, it was soft and possibly getting differing traction conditions from one side to the other as you ran , i want to say it will feel light on one side or the other but its not quite the right description and will feel less regular than hunting from toe in
but all influences interact
Karl our busa was "hunting " too about 2-4 times a second ...., that i can do without
maj/Greg (same as OzBooster, yes?)
The possibility of differing L-R traction causing hunting didn't occur to me at WOS but afterwards the possibility was suggested.
One would think if the hunting was due to L-R accel/traction differences, hunting would stop during decel
So i just looked at my 5 mi log.
Last pass, 3rd gear / 205mph I got spooked by the hunting and briefly went to about 50% throttle, 199mph.
In my mind i think the hunting must have stopped bc I got back on the gas hard.
But the logs show 1-2.5 degree heading changes even during that brief decel.
I don't understand what's going on, but I LOVE this stuff.
And, i love the Racepak logging system. I am a dumb-azero at set up and use, but with the help of my vendor (Greg Kelly), and help at WOS (Donny Cummins), i am inching up the learning curve...
I feel your pain about dealing with a twitchy Busa on the salt, you KNOW I do
