Which cars do the Street Zero-A Coilovers for GZEA14H fit?

Cusco USA lists part number 1H1 61N CN for the Toyota GR Corolla (GZEA14H, 2023-2026). The Street Zero-A Coilovers for GZEA14H replace the factory dampers and springs on the cars listed under Applications. Check the model and trim against the notes before ordering.

Why twin-tube dampers?

A twin-tube damper has an outer tube that holds a large reserve of oil around the working cylinder. That gives a smooth, quiet ride on rough roads and keeps the damper consistent in everyday use. Monotube dampers suit sustained track use better, while twin-tube designs suit a road car.

How is the ride height adjusted?

The damper bodies are threaded along their full length, so height is set by turning the body in its lower mount. Spring preload and damper stroke stay the same as the car is lowered, so ride quality holds up. An alignment is needed after any change.

Can the spring rates be changed?

Cusco offers optional spring rates for this kit when it is ordered, and springs can be changed later as well. The standard rates are chosen for road use on these cars, so most owners keep them. Contact us before ordering if a different rate is wanted.

Is it comfortable enough for daily driving?

Yes. Cusco designs its street coilover lines for road use, and matches the damping to the supplied springs. The ride is firmer than stock and body roll is reduced, and the damping can be softened for the commute. Pillowball mounts add some road noise.

Description

Cusco Street Zero-A Coilovers for GZEA14H Toyota GR Corolla

Cusco’s Street Zero-A Coilovers for GZEA14H Toyota GR Corolla replace the factory dampers and springs with twin-tube dampers of Cusco’s New Quiet design, with 40-step damping adjustment front and rear, and 7 kg/mm front and 8 kg/mm rear springs. The bodies are threaded along their full length, so ride height is set without changing spring preload or damper stroke. Cusco builds the Street Zero-A line for street driving, so the kit suits a car that is lowered for looks and handling and still driven every day.

Design and Performance

A twin-tube damper keeps a large oil volume around the working cylinder, which helps ride comfort and keeps the damper quiet on broken roads. The adjusters let the damping be firmed up for a canyon drive or a track day and softened again for the commute. The Street Zero-A Coilovers for GZEA14H run pillowball upper mounts, which sharpen steering response at the cost of a little more noise in the cabin.

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.
