Does the Nitron Zenos E10 NTR-R1 kit fit both the E10 and the E10 S?

Yes. The Nitron Zenos E10 NTR-R1 coilover kit is built for both the E10 and the E10 S. Because every kit is sprung and valved to order, Nitron can tailor the setup to each car’s specification and how the owner drives it, whether that’s mostly on the road, at track days or in sprint events.

Does the Nitron E10 NTR-R1 change the suspension layout?

No. The Nitron E10 NTR-R1 bolts into the factory mounting points of the E10’s all-round double wishbone suspension and uses an OEM-type rear layout. The geometry Zenos developed stays as it is, which keeps the install simple and keeps the car’s balance familiar while the Nitron dampers give you far more control over how it moves.

Why does damper quality matter so much on a lightweight car like the Zenos E10?

With so little weight on each corner, the Zenos E10 is very sensitive to damper friction and control. The Nitron E10 NTR-R1 uses low-friction internals that react to small inputs. That keeps the tires following uneven surfaces instead of skipping over them, which shows up as more grip and a calmer, more confident car.

How do you adjust the damping on the Nitron NTR-R1?

Each Nitron NTR-R1 damper has a single adjuster that changes bump and rebound together along a curve Nitron sets for the car. Turning it firmer stiffens both directions at once, and turning it softer relaxes both. Switching between a road setting and a track setting takes a few clicks per corner, with no separate circuits to balance.

Can the Nitron Zenos E10 NTR-R1 be serviced and rebuilt?

Yes. Every Nitron Zenos E10 NTR-R1 damper is fully serviceable, so it can be rebuilt, revalved or fitted with different springs as needed. For a low-volume car like the E10, that means the suspension can be kept in top condition long term instead of being replaced.

Description

Nitron NTR-R1 Coilover Kit for Zenos E10 / E10 S

Zenos built very few E10s, and today every owner is responsible for keeping theirs sharp, often without a dealer network to lean on. Nitron backs a car like this properly. The Nitron Zenos E10 NTR-R1 coilover kit fits both the E10 and the E10 S. It gives these featherweight roadsters a damper that has more in common with a race car than with the components they left the factory with. On a car this light, small differences in damper friction and control show up immediately through the steering and the seat. A sticky damper makes the chassis feel nervous over patched tarmac. A well-controlled one lets it flow. One adjuster per corner sets bump and rebound together, so you can tune the car for a cross-country blast or a track day in a few clicks. The rear follows the OEM suspension layout, so the Nitron E10 NTR-R1 bolts into the factory mounting points of the all-round double wishbone suspension without changing the geometry Zenos developed.

Unique Technology

The Nitron NTR-R1 comes out of Nitron’s race program and shares much of its internal hardware with the NTR-R3 used in international motorsport. Leaving off the remote canister keeps each unit compact and the install simple. On an open car with exposed suspension and little room between the wishbones, that matters more than it would on most cars. Very low internal friction lets the Nitron E10 NTR-R1 respond the instant a wheel starts to move. With so little mass resting on each corner, that responsiveness keeps the tires in contact over rough, uneven surfaces where a stiffer, stickier damper would let them skip. The damping also resists fade, so the balance you set on the first lap of a session is still there when the checkered flag comes out.
- Basic Damper Design:
  1. End Eye / Top Mount
  2. Damper Piston & Shim Stack
  3. Shaft / Rod
  4. Floating / Separator Piston
  5. Suspension Oil
  6. Compressed Nitrogen Gas

Bespoke Engineering

Each Nitron Zenos E10 NTR-R1 kit is assembled by hand after the order is placed. Springs and valving are chosen for how that particular car is driven, whether that’s an E10 used for weekend road trips, an E10 S that splits its time between the road and track days, or a car set up for sprints and hillclimbs. Hard-anodized and titanium-finish components keep weight down on a chassis designed around low mass, and they resist corrosion on a car that sees more weather than most because it has no roof. Keeping an independent British sports car on the road for the long term also means using parts that can be maintained. Every Nitron NTR-R1 damper can be fully serviced and revalved, so the kit can be rebuilt and adjusted to suit the car for years.

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.
