What does Nitron's Ferrari 308 NTR-R1 Coilover Kit adjust?

Each corner has one control that changes compression and rebound together. That keeps the 308 NTR-R1 simple to set up, and you can change how the car feels with one setting per damper.

Does this Ferrari 308 NTR-R1 keep the OEM rear suspension?

Yes. The kit is built for the OEM rear suspension type, so the rear keeps the original layout and the Nitron spring and damper take the place of the factory parts.

Can I change the ride height with this kit?

Yes. The Ferrari 308 NTR-R1 has adjustable spring perches, so you can set ride height and corner balance to suit how the car is used.

Does the Ferrari 308 NTR-R1 have remote reservoirs?

No. The NTR-R1 uses an internal reservoir, so there are no hoses to route or reservoirs to mount. That keeps the installation tidy, which helps in a car with limited space around the suspension.

Can I order different spring rates for the 308?

Yes. Custom spring rates are available by contacting us directly, which is worth doing if your car is set up for mostly road or mostly track use.

Do I need an alignment after fitting the kit?

Yes. A professional alignment is required after installation so ride height and geometry are set correctly.

Description

Nitron NTR-R1 Coilover Kit for Ferrari 308 GTB / GTS

The Nitron Ferrari 308 NTR-R1 Coilover Kit is for 308 GTB and GTS owners who want modern, adjustable damping on a car whose original dampers were designed decades ago. The Ferrari 308 NTR-R1 replaces the spring and damper at each corner with a passive nitrogen-pressurized monotube that has one combined compression and rebound adjustment, so you can tighten or relax the car’s behavior with a single setting. Adjustable spring perches set ride height, race springs come with the kit, and the rear keeps the OEM suspension type. For a mid-engine V8 car that gets driven on winding roads, at track days, or both, the Ferrari 308 NTR-R1 is a direct way to put control back into the suspension.

Unique Technology

A mid-engined, rear-drive car like the 308 rewards good damping, because the weight sitting behind the seats decides how the car turns in, how it settles mid-corner, and how it puts the power down on exit. Each Ferrari 308 NTR-R1 damper has an internal reservoir, so there are no remote hoses and nothing extra to find room for around the wishbones. One control per corner changes compression and rebound together, which keeps the setup simple. Start in the middle, drive the car, and move the settings a little at a time until the body movement suits the roads you use.
- 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 hand assembles every kit to order in the UK, and builds the Ferrari 308 NTR-R1 around the GTB and GTS, which use unequal-length wishbones with a coil spring over a telescopic damper at each corner. The kit keeps that arrangement, including the OEM rear suspension type, so the car’s original geometry stays in place. Race springs and adjustable perches let you set ride height and balance the car the way you want it.

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.
