What is the 7Design Rear Diffuser for LB634 Lamborghini Temerario made from?

The ARIA Rear Diffuser for LB634 Temerario is laid up from pre-preg carbon fiber against tooling made by 7Design and built in the USA. Twill carbon is the standard finish, with forged carbon and tinted twill carbon offered as paid options. All three share the same structural layup, so the finish is chosen on surface character.

What does the rear diffuser actually do?

It manages the air leaving the Temerario underbody, which is what settles the rear of a mid-engined car as speed rises. 7Design developed the ARIA diffuser in computational fluid dynamics rather than styling it alone, and the firm describes the intent as measurable aerodynamic results rather than appearance.

Does the ARIA diffuser fit around the factory exhaust?

It is designed around the standard rear end of the LB634 Temerario and locates on the factory mounting points. 7Design has not published clearances for aftermarket exhaust systems, so owners running a non-standard rear section should confirm fitment with the team before ordering rather than assume the cut-outs line up.

Is the diffuser a direct replacement for the factory part?

It fits the Temerario rear valance on the existing mounting points and needs no cutting or drilling. 7Design has not published a factory part number the ARIA diffuser supersedes, so no such claim is made here; the installing shop should confirm what is removed on a specific car before work begins.

How difficult is installation?

Level-2 install difficulty. The diffuser locates on the existing Temerario rear mounting points and needs no cutting, though it sits low and wide and its alignment against the rear valance is visible from behind, so a shop that fits carbon aero regularly is worth the booking. Hardware and final alignment sit with the installing shop.

Description

7Design ARIA Carbon Fiber Rear Diffuser for LB634 Lamborghini Temerario

7Design’s ARIA Carbon Fiber Rear Diffuser for LB634 Lamborghini works where almost nobody looks and everybody feels it, managing the air leaving the underside of the Temerario to steady the car as speed builds. The sculpted form carries the ARIA design language into the rear architecture so completely that it reads as original equipment, with strake edges sharp enough to reward a second look. Pre-preg carbon over 7Design’s tooling, built in the USA, in twill, forged or tinted finish. For the owner who wants the rear of the car resolved rather than merely decorated.

Design and Performance

A diffuser is the least visible aerodynamic component on a mid-engined car and among the most consequential, because it decides how cleanly air leaves the underbody and therefore how planted the rear feels as speed rises. 7Design developed this one in computational fluid dynamics and then spent the design effort on making it look like it belongs, pulling the ARIA language down into the rear valance so the transition from factory bodywork to carbon is difficult to find. The strakes are finished with edges crisp enough to hold up under the close inspection this car attracts. Fitted, the ARIA Rear Diffuser for LB634 Temerario resolves the lower rear in a way the factory valance never quite manages.

Built in the USA

Applications

Lamborghini Temerario: LB634 | 2025-present | 4.0L Twin-Turbo V8 Hybrid

Notes

Sold individually
Offered in twill carbon fiber as standard, with forged carbon and tinted twill carbon available as options (both priced above the standard twill finish)
Each ARIA component is laid up to order in the USA, so it is listed on backorder and the team confirms build time at the point of order

About 7Design

7Design is a design house based in New York that fuses carbon, art and performance for a short list of the world’s most desirable cars. Every ARIA component begins as a digital model refined over thousands of hours, with proportions, aerodynamic validation and panel integration settled before a mold is cut. Development runs in computational fluid dynamics, so the aero surfaces do measurable work rather than merely suggesting it, and every piece is built in the USA from the finest carbon fiber the firm can source. Twill, forged and tinted carbon are offered across the range, each treated as a considered choice rather than an afterthought.

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.
