It has been discussed in various threads, track pads will likely be needed with the iron rotors for any serious tracking.
Interesting stuff indeed, and I do appreciate the input. However nonetheless, the rotors were measured and confirmed warped, both mathematically and visually.

The brakes are just the tip of the iceberg too; I could go into a whole thread about the let downs this car has provided from one track day...but quite simply, I do not have the time.

Massive disapointment in many ways.

At least it's a really fast street car which at least looks like it could handle a racetrack...
