What is a close ratio gear kit and why would I want one?

A close ratio gear kit features gear ratios that are spaced more closely together than stock. This allows your engine to stay within its peak powerband more consistently during acceleration, leading to improved responsiveness and faster lap times on a track.

Does this gear kit include everything needed for installation?

This kit includes the specific gears required for the close ratio setup. However, it is an internal transmission modification, and you will need to consult with a professional installer regarding any additional seals, bearings, or hardware that may be necessary for the complete transmission rebuild.

What kind of performance difference can I expect with this kit?

You can expect a significant improvement in acceleration. The engine will rev more quickly through the gears, making the car feel much more potent and responsive, especially in situations where rapid acceleration is needed, like track driving or spirited road use.
