These are really nice! The drivers side mat bolts to the seat rail on the right side and also has the floor clip on the left side.
These are bigger and provide more floor coverage than the mats that came with my 05 STi, especially the rear mats.
The paperwork that came with the mats reads "2006 STI, SCI440B202, BLACK, 4 PIECE SET, MADE IN CANADA" These mats fit my 05 Sti very well and look to be high quality.
