What are the four adjustments on each damper?

Each corner has high speed compression, low speed compression, high speed rebound, and low speed rebound. The low speed settings shape how the car pitches, rolls, and settles, and the high speed settings shape how it deals with curbs and sharp bumps.

How does the kit fit with the OEM rear suspension?

The rear keeps its original OEM suspension layout. The kit is built to suit that arrangement, so the Nitron spring and damper replace the factory parts in the same place.

Does the rear of the car need any hoses?

No. The rear uses piggyback reservoirs that mount directly on the dampers, so there are no hoses to route at the back. Only the front reservoirs connect by hose.

Can I order other spring rates for the Supercopa?

Yes. Custom spring rates are available by contacting us directly, which is worth considering if you run a particular circuit or tire often or have changed the car’s weight.

Do I need an alignment after fitting the kit?

Yes. Adjustable top plates are included, and a professional alignment is required after installation so the new ride height and any camber changes are set correctly. The Nitron Supercopa NTR-R3 gives you more to adjust, so a proper setup session is worth the time.

Description

Nitron NTR-R3 Coilover Kit for MK2 SEAT León Supercopa

The Nitron MK2 León Supercopa NTR-R3 Coilover Kit is for owners who need to set the car up for each circuit and not rely on one fixed compromise. The Supercopa is a purpose-built race car that SEAT Sport builds from a bare shell, with a turbocharged 2.0-liter TFSI driving the front wheels, and the Nitron Supercopa NTR-R3 gives each corner four independent adjustments, high speed and low speed for both compression and rebound. That lets you control how the car pitches, rolls, and settles separately from how it takes a curb or a bump. Hose-connected reservoirs are used at the front and piggyback reservoirs at the rear, adjustable spring perches set ride height and corner weights, and the OEM rear suspension type is retained. For a car that already lives on track, the Supercopa NTR-R3 gives you the control to tune it properly.

Specialized Bi-Axis Hose Fittings

The front dampers connect to their remote reservoirs by hose, so the way each hose leaves the damper affects how clean and safe the installation is. Nitron fits Bi-Axis connectors that rotate 720 degrees on two axes, which lets you turn each hose toward its reservoir before you secure it. That gives every front line a short, natural route with no tight bends or tension on the fitting, which is worth having on a car that sees hard use. The rear needs none of this, because the piggyback reservoirs sit directly on the dampers.

Unique Technology

Racing a front-drive car means managing weight transfer lap after lap, and the NTR-R3 separates that job from the job of absorbing bumps. Low speed compression and rebound govern body movement, so they decide how the car dives under braking, rolls into a corner, and squats as the power comes on. High speed compression and rebound govern sharp inputs such as a curb, a bump at the apex, or a ripple on the exit, so they decide how well the tires stay on the surface. Each of the four settings is independent, which means you can adjust one without disturbing the others. The dampers are passive nitrogen-pressurized monotubes with remote reservoirs, hand assembled to order in the UK and fitted with race springs.
- 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

Nitron builds the Supercopa NTR-R3 around the MK2 León Supercopa, with damper length, stroke, hose length, and perch positions chosen for the car and not cut down from a universal part. The rear stays as the OEM suspension type, and the Nitron spring and damper package fits into that layout. The factory geometry is left in place, and the car gains a level of damping control that is built for circuit use.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California.

That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.

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.
