Just an FYI...

I just took a look at my old 99 Taco calipers...

The 199mm/231mm measurements must be for the length of the caliper body...Thats the only measurement that even came close on my old calipers.

My calipers measured aboot 8 5/8" (219mm).

That means the Tundra calipers SHOULD be:

199mm = 7.83"
231mm = 9.09"

Also, my Taco calipers are stamped S12WN.

Anyway, this makes me wonder what the difference is between the 199mm Tundra calipers and the stock 219mm Tacoma calipers... Are the 199mm REALLY an upgrade over the stock Tacoma calipers?

AND if there isnt really an upgrade between the 199mm and 219mm's, its no wonder Toyota had to upgrade the brakes on the Tundras...
