ACS Composite C7 Corvette ZR1, Z06 & Grand Sport Rear Quarter Extensions

One of the biggest complaints we get from Z06 and Grand Sport owners is the lack of a matching fender extension for the rear wheel. Inspired by the front z06 fender extensions, we answered the call and ported over the extensions to the rear of the C7 Corvette. Note: Will not fit C7 Stingray

The ACS C7 ZR1, Z06, & Grand Sport Rear Quarter Extensions fulfill that missing void on your back wheel. The extensions will provide that missing protection along the inside paint surfaces. Now, you will have cohesive coverage and aesthetics front to back!

The ACS Rear Quarter Extensions come pre-painted in Carbon Flash Black ideal for anyone that have previously upgraded their fronts to the carbon flash version.


How it's made 

Parts are digitally designed to ensure a specific fit to the Corvette. There is nothing universal about an ACS product. Our engineered parts are made in a PC Composite plastic via injection and painted ‘Carbon Flash Black’ specifically in order to match the Corvette's other trim parts, including the diffuser, fender inserts, bumper grill,  and hood insert. fitted, you will wonder why it wasn’t always there. Once fitted, you will wonder why it wasn’t always there.
