As a result of the discussion on the Toyota conversion a short time back I
started reexamining the underlying equations.
My conclusion is that the Toyota calipers are NOT superior to the TR6 calipers
and that the testing methodologies were flawed.
The following is the e-mail that I sent to VTR informing them of the problem.
I apologize for any inconvenience that I might have caused the Triumph
community.
