According to EBC catalog:
Slotted/dimpled rotors are now available.
Different high performance pads.
Interestingly, the pads (D906) are same as 2004+ Sienna's (front) even though Tacoma's rotors are smaller (10.8" vs. 11.7").
I got hold of a 2004 Sienna and found front pads are fully interchangable. The only difference is relief cut (Sienna is angled and Tacoma is vertical). Not sure of thickness since Sienna's almost worn out.
