Size of front brake rotor
 

Does anyone know the correct size offhand of the front disc on an '01 SSEi?

Is it 10.93 or 11.93"?

For an SSE/SSEi it would be whats commonly referred to as 12 inches, but yes its 11.9 something.

For an SE its 10.9something also known as "11 inches"

The SSE/SSEi difference only applies to the 00+ models.
