Hi rotary maniac. S5 rotary motor has been modified with Toyota W58 tranny and Hoosier drag slick size (26.0X9X15 D05). What's the rear end gear ratio suit for above setup. Example 3.9, 4.1, 4.3, 4.55, 4.87 or 5.1.



Sorry the w58 tranny ratio 1st:3.285 2nd:1.894 3rd:1.275 4th:1.000 5th:0.783



Hope can get from your advice. Thanks
