Custom Carbon Fiber

We are able to make most parts in carbon fiber. We are interested in custom jobs in the form of special orders without minimum quantity requirement. Any new production product recommantion is welcome. If you would like to obtain more information, you can email to racingproudctgroup@gmail.com.



Sponsorship

Yes we do offer sponsorships. Please email your written sponsorship proposals and recent photos of your car to racingproductgroup@gmail.com. We do have requirements.We will need to know how you can help us promo RPG brand and must carry RPG stickers on the car, need you to provide sponsored product install photos, put RPG as your sponsor on the IG front page introduction and each post. We will be happy to review your qualifications.



Product Made with Carbon Fiber

Carbon fiber material is a piece of cloth that needed support to form any shape. We use fiberglass backing to construct the support skeleton.



Quality of Carbon Product

We use all different production procedure and progress among all RPG products. - Product made with one-piece carbon sheet - Product made with multiple sheets - carbon sheet wrapped around the skeleton - carbon sheet integrated into the mold It depends not only on the product but regard to the optoins of your preference. We integrate and make sure we brought to you with the best finish proudct possible. All of our products use clear coat finish. Clear coats are shiny and durable, and they give you the nice “wet” look as opposed to a duller look from gel coats. All products are made to order to fulfill different requirement and guarantee the freshness of the materials.



Warranty

We provide 6-month limited clear coat warranty. We modeling and test fitting all parts before molding for production. We guarantee fitment for all US-modeled vehicles, unless we specifically indicate otherwise. But customers need to understand that no after-market body parts will fit exactly like OEM. It is normal and you are expected to do minor adjustments for a good fit. We are trying to best quality possible aerodynamic parts to our customer and improve ourselves overtime. Our warranty extends only to vehicles that have not had any bodywork done. As a precaution, test fit all parts before you cut/paint/drill the items.



Maintain

Carbon fiber product is durable and strict, but still needs care and maintenance to stay in condition. More specifically, keep the products clean, minimize exposure to the sun, and wax when necessary.



Carbon Weave Pattern

1 x 1 Plain Weave

Plain Weave, also known as plain weave. Its over-under pattern is the pretty standard pattern. Not the strongest of weave but is solid. Easiest to handle without making the fibers on the ends too messed up. Other weaves fall part incredibly fast, but make up for this is some cool patterns and more strength in the direction of the weave. It is the tightest weave. RPG Carbon’s products are made standard with this pattern, unless otherwise select in product option.



2 x 2 Twill Weave

This pattern has grown immensely in popularity. It represents the diagonals that are synchronized. Is braid over-over-under-under. Most popular pattern that many carbon fiber factories use to make details. This pattern is elastic and it is good for use with complex shapes because its weave is looser. Some believe twill weave is easier to work with than straight weave. This is partially true as the weave is not as tightly woven as with straight weave fabric. However, twill weave can be easily distorted because of its complexity.



12K 10 x 10 Plain Weave

Take Plain Weave Carbon to the Next Level. This brawny, 12K carbon fiber is a bold, hardworking version of traditional plain weave, with every thick yarn of fabric like a glossy brush stroke. Its high-contrast surface features both brilliant highlights and contrasting deep, dark shadows. Perfect for the fender, hood and trunk.



3K 12x18 HoneyComb Weave

Add a Honeycomb Look to Carbon Fiber. This hexagon pattern almost slithers across the fabric surface like a reptile, lending itself to a variety of interesting applications. Patterned styles, like this interlocking honeycomb, not only create a unique look, but help to maximize the inherent strength properties of the carbon fibers from which they're made. Its pattern will not affect the ultimate tensile strength or stiffness.



Kevlar / Carbon Hybrid (Yellow) Weave

Impact Resistance and Carbon Strength Combined. By combining the properties of both materials in each layer, this fabric delivers a high strength-to-weight ratio, high conformability, impact resistance, abrasion resistance, dimensional stability, and fatigue resistance.



Prodcut Option

FRP Finish Color

Available in your selection of painted "Primer White" or "Primer Black" for your purchase made for FRP product.



Inside Laid with Pre-Weaving Fiber

For certain product, the backside(inside in this case) is presented with flberglass finish. Fiberglass are work as skeleton support of carbon fiber layers. Please see below left picture for example. With option of "Inside Laid with Pre-Weaving Fiber" which will cover the fiberglass skeleton from exposure. Pre-weaving fiber are shown in the below right picture.



Clear Coating

Carbon Fiber clear coating is available in your preference of Gloss or Matte finish.



Carbon Fiber Weave Pattern

Please see above "Carbon Fiber Weave Patter" category.
