Which cars does the Close-Ratio Gear Set for ZN6 fit?

Cusco USA lists part number 965 028 A for the Toyota 86 (ZN6, 2017-2021), the Subaru BRZ (ZC6, 2013-2021) and the Scion FR-S (ZN6, 2013-2016). The Close-Ratio Gear Set for ZN6 goes inside the factory manual gearbox, so the gearbox has to come out and be stripped to fit it. Check the model and gearbox against the Applications list before ordering.

What does a close-ratio gear set change?

It narrows the gaps between gears, so the revs drop less on each upshift and the engine stays closer to the rpm where it makes its best power. On a circuit or a hill climb that means stronger drive out of every corner. The trade-off is a busier gearbox on the road, with more shifts needed to reach cruising speed.

Will it make pulling away harder?

Yes, a little. First gear on this set is taller than the factory first gear, so the car needs more revs and more clutch slip to pull away, especially on a hill or with a passenger. Most competition drivers accept this because first is rarely used once the car is moving.

Is it suitable for a road car?

It works on the road, but it is designed for competition. Closer ratios mean more shifts in town, and gear whine can be more noticeable than with factory gears. Owners who mostly drive on the road usually get more from a limited-slip differential or a final drive change first.

A transmission specialist. The gearbox has to come out of the car and be stripped down, and the shafts, bearings and synchronizers need to be inspected and set up correctly when it is rebuilt. It is efficient to fit a limited-slip differential or a new final drive at the same time.

Cusco Close-Ratio Gear Set for ZN6 Toyota 86, ZC6 Subaru BRZ and ZN6 Scion FR-S

Cusco’s Close-Ratio Gear Set for ZN6 Toyota 86, ZC6 Subaru BRZ and ZN6 Scion FR-S replaces 1st and 2nd gears in the factory manual gearbox, along with the counter shaft they run on, with ratios chosen to close the gaps between gears. Raising the lower gears closer to the upper ones means a smaller drop in rpm on each upshift, so the engine stays nearer its power peak through a corner sequence or a sprint stage. It suits a car built for circuit, hill climb, gymkhana or rally use, where the car lives in the middle of the rev range.

Design and Performance

Gear ratios set how far the revs fall when the driver changes up. Factory ratios are spread to suit everything from pulling away on a hill to quiet highway cruising, which leaves big steps that drop a tuned engine below its best rpm. The Close-Ratio Gear Set for ZN6 narrows those steps. The trade-off is a taller first gear than stock, so pulling away needs a little more clutch and revs, which matters most on the road and on a standing start.

Close-ratio replacement for 1st and 2nd gears
Smaller rpm drop on each upshift

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
