- Genuine Tomei
- Gearing: 3.692
- For front and rear differential
This gear setup is best suited for use with the BNR34 Getrag and Holinger transmissions for up to 500HP. When using the 3.545 final gear ratio on Fuji Speedway, the acceleration is slow which results in slower times to reach top speed. Both 3.9 and 4.1 ratios deliver great acceleration but it is not ideal for the GTR and larger tracks like Fuji Speedway. The difference of 0.153 for the ratio of 3.692 delivers a large change in the cars gearing balance. This best suites both acceleration and top speed.
