Introduction
In replacing the differential final which ATS discontinued a few years ago, ATS has released a new mission final for S2000. By changing the secondary drive gear only, the ATS mission final can provide the same impact as the shorter differential final with a lower price.

Price
Model # R7A23-02     Price $480.00
(The price includes the EMS air shipping from ATS Japan)

Gear Ratio
The teeth number 23 (stock AP1 - 25 & stock AP2 - 24) produces a secondary final gear ratio of 1.261. The gear ratio is shortened by 8.7% for AP1 and by 4.3 % for AP2, which is equivalent to 4.46 and 4.28 for AP1 and AP2 respectively in the differential final.

Note:
1) For AP1, the secondary shaft for AP2 is required to install ATS mission final. (please refer to the diagram below)

2) In exchange for a faster acceleration, the vehicle top speed is reduced according to the shorter gear ratio.

3) Your speedometer will indicate 8.7 % (AP1) and 4.2 % (AP2) faster value than the actual.
