VASL R1-Style Pre-Preg Carbon Fiber Rear Diffuser for 2014–2019 Corvette C7
Transform the rear profile of your Corvette C7 with the VASL R1-Style Pre-Preg Carbon Fiber Rear Diffuser.
Designed for Corvette C7 Stingray, Z06, Grand Sport, and ZR1 models, this one-piece replacement diffuser replaces the factory lower rear valance while adding a deeper, wider, and more aggressive multi-fin appearance.
The diffuser features an integrated center quad-exhaust opening, a defined license-plate mounting area, and multiple vertical fins across the left and right lower sections. Together, these details create a more purposeful rear profile while retaining the recognizable center-exhaust layout of the C7 Corvette.
Each diffuser is manufactured from pre-preg 2x2 3K carbon fiber and finished with a gloss UV-resistant clear coat that highlights the depth and consistency of the twill weave.
This product is a complete one-piece replacement rear diffuser and lower rear valance. It is not a tape-on overlay, diffuser-fin add-on kit, or complete rear bumper assembly.

7. Confirm alignment around the exhaust opening, outer bumper edges, license-plate area, and upper mounting locations.
8. Transfer and reuse factory hardware or components where required. Obtain additional clips or hardware if necessary.
9. Assess any mounting-tab modifications or minor adjustments only after full test fitting has been completed.
10. Install the mounting hardware without fully tightening each mounting point.

Important:
⚠ Do not drill, cut, trim, or modify the product before completing a full test fit
