I have 3.73 ratio in mine.


The speedo in mine is out about 15%, but with the 18s on, its only about 10%


You can get them corrected for about $140 for a level 1 or 2 dash, or about 200 i think it was for a level 3.
And if you have a VS Speedo like i do, expect to pay $340



No clue about 1/4 times sorry.
