Ricardo,
They are the same size as the China gauges.
Kirk actually sent the Brazilian gauges to China to be copied. A copy of a copy if you will. I love the back-lit look of the China gauges, but, well... you know the rest.
The VDOs are what we use in the speedster, spyder, and s-90. Unfortunately, they are becoming harder to get. VDO is very good about making sure I have enough for my builds, but not on "extras". I am currently backordered on 60+ sets :-/
