Why retain the OEM top mounts rather than replacing them?

The P13's factory top mounts are engineered to isolate noise and vibration at a level that aftermarket alternatives typically compromise. Retaining them means the RS kit delivers meaningful suspension improvement without introducing NVH trade-offs that would make the car less livable on the road. For a car that gets driven regularly, that matters.

How does the RS differ from the RS3 on the P13?

The RS uses a single combined adjuster controlling compression and rebound simultaneously across 24 clicks. The RS3 separates high and low speed compression into independent circuits, giving more precise control over specific handling characteristics. The RS is the better starting point for road-focused drivers who want straightforward setup; the RS3 suits drivers who want the range to develop a setup across different circuits and conditions.

Description

Nitron RS Coilover Kit for P13 McLaren 540C, 570GT, 570S, and 600LT

The Nitron RS Coilover Kit for the P13 McLaren 540C, 570GT, 570S, and 600LT gives road-focused drivers a wide range of effective, easy to use damping control without departing from what makes the P13 platform work as a daily driver. The kit retains the McLaren’s OEM top mounts, preserving the factory noise and comfort characteristics while delivering suspension performance well beyond what the stock setup offers. Every RS kit is custom built, custom sprung, and hand-built with ultra-low friction components using titanium and hard-anodised materials that resist corrosion, hold damping fade-resistant through extended road and track use, and hold up through winter driving season after season. Fully serviceable, no remote canister required.

Unique Technology

Nitron builds every shock around precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the room to develop each application properly on its own terms, without cutting corners on part quality or how components work together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; quality control isn’t a final step here, it runs through the entire process. New materials, finishes, and processes are validated extensively before they’re brought into production, with proprietary Nitron technologies woven throughout to produce shocks that hold up against the competition on both road and track. That level of engineering discipline is what the brand has been built on.
- 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 doesn’t start with a generic damper and work backward from there. Every application is developed from the ground up, with components, spring rates, and damping characteristics determined by the specific platform rather than borrowed from something adjacent. The geometry, weight distribution, and suspension travel of the P13 McLaren shape the design from the start, not as corrections added later. That’s what separates a kit engineered for this car from one that was simply made to fit it.

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. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. 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.
