How does the Rear Diffuser for Ferrari SF90 differ from the factory part?

The Rear Diffuser for Ferrari SF90 was shown on the RYFT build as a redesigned unit with larger fins than the factory diffuser, finished in exposed carbon fiber with a one by one weave. RYFT and the press described it as stabilizing airflow at the rear. Bulletproof Automotive confirms the mounting with RYFT before ordering.

Does the RYFT diffuser work with the RYFT titanium exhaust?

Yes. RYFT built its own SF90 with both the diffuser and its titanium race exhaust, which exits through dual oval tips. Ferrari places the SF90 tailpipes high on the rear, above the diffuser, so the two parts occupy different areas of the tail. Both are sold separately by RYFT.

Which SF90 versions is the RYFT diffuser listed for?

RYFT lists it for the SF90 in a collection covering the Stradale and the Spider, without restricting it. Ferrari carried the Stradale aero package over to the Spider unchanged. The SF90 XX versions use a redeveloped trimaran tail and their own diffuser, so the RYFT part is not listed for them.

Is the RYFT diffuser worth it without the rear wing?

Yes, for an owner who wants a carbon rear without changing the shut-off Gurney. The diffuser alone transforms the lower rear, and it can be joined by either RYFT wing later. For a car used on track, we would pair it with the RYFT Type 1 active wing for balance.

How should a carbon diffuser be kept clean?

A diffuser sits under the tail where road film and brake dust collect. Rinse it thoroughly, wash with a pH neutral shampoo and a soft brush between the fins, and dry by hand. A UV stable ceramic coating makes grime easier to remove and protects the clear finish from fading.

Description

RYFT Carbon Fiber Rear Diffuser for Ferrari SF90

The RYFT Rear Diffuser for Ferrari SF90 is the most expensive carbon part RYFT makes for the car, and it has the most visual weight of anything below the bumper line. RYFT showed it on its SF90 build as a redesigned diffuser with larger fins, said to steady the airflow leaving the underbody. Because Ferrari mounts the SF90 tailpipes high, the diffuser has the lower rear almost to itself, which is why we rank it the strongest single RYFT piece for the rear view.

Design

Ferrari kept the SF90 tail sleek by lowering the powertrain, replaced round tail lights with horizontal light rings and raised the exhaust outlets, leaving clean space below. RYFT fills that space with deeper fins than the factory part and lays the diffuser up in the 1×1 carbon weave it lists for the SF90. It matches the RYFT wings above it and the RYFT titanium race exhaust that exits over it.

Features

Redesigned diffuser with larger fins, as shown on the RYFT build
Carbon fiber in the 1×1 weave RYFT specifies
Fills the clean lower rear left by the high-mounted SF90 exhausts

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.
