Great Quality Items From ACS.
All the products I have received from ACS are top quality in my opinion. I ordered from other suppliers because they were cheaper , but the fit and finish was garbage. Lesson learned. I will order any future products from ASC.
"High-Quality ACS Products with Easy Install"
I can only recommend the products of acs. High quality and easy to install. The only negative point is the high delivery fee from fedex 1000$ for an initial 3500$ order

"Great Products, Service, & Shipping"
I learned about ACS products from youtubers who have their beautiful corvettes upgraded, and I felt some products are actually useful as well as good in appearance. The service is good that pre-communication being very responsive and quick, even in Covid-19, shipping was super fast, installation with videos can be found on Youtube being easy, products being well protected and in great condition even further shipped across the ocean. And definitely looks beautiful after installed. Hope to see more interesting items and also for C8 in the future.

Outstanding Functionality and Visually Flawless.
Once again, ACS Composite has provided me with mods for my 2016, Z51 C7 Corvette Stingray coupe that are functionally and visually outstanding! The rear dual diffuser fins, rear fascia extensions, and jacking pucks all arrived fast and the installation of these high quality items was a perfect fit and finish. Highly satisfied and highly recommended

"Perfect Match for Z06 Stingray"
Excellent product. The way the z06 should have come. Diffusers match perfectly
Top-Notch Product for Corvette.
Absolutely A1! The best parts I have ever put on my Corvette. I don't put cheap overseas mods on my $90k vette.
"Outstanding Quality, Patience Required"
I have a 2019 Corvette Grand Sport that received considerable damage to the stock passenger side rocker. This was really bad news, but the ACS Composite Z06 side rocker kit fixed the problem with the result of an improved appearance vs. the stock parts. I also installed the ACS rear diffuser fins while I had the Corvette elevated on jack stands. Bottom line: both parts kits (side rockers and diffuser fins) are of outstanding quality and they look great on the Corvette. However, be patient and deliberate with your installation actions. Some screw mounting holes (stamped outline on the side rockers) required drilling for mounting on the Grand Sport. The drilled holes do not line up perfectly with the stock threaded inserts; it is necessary to elongate the holes for a proper fit. Be careful when elongating the holes with a drill bit because a shallow insertion could allow the drill bit to slip out and damage the finished surface of the side rockers. The diffuser fins also require careful work because of the limited clearance available to insert the screws and to thread screws into the fins. This challenge can be mitigated considerably by removing the three diffuser panel screws on each outboard side of the diffuser panel. Screw removal will allow you to pull the diffuser panel down for better access to thread the mounting screws into the fins. I have an exceptionally well equipped shop and decades of serious automotive work experience. These projects (side rockers and diffuser fins) required extensive application of the subtle tricks that I have learned over the years. Patience and careful, deliberate procedures will eventually give you the results that you want. Expect these projects to require much more time than you anticipate, but the results will be worth it.
Great Product, Currency Issue.
ACS makes very high end add ons for my C7 Stingray.Would purchase more except paying in U.S funds is holding me and other Canadians back.Always have to wait for the sales that are few and far between.
"Easy install, great addition."
Great product, easy to install, looks great.
Great Purchase Experience.
Very happy, would purchase again.
Excellent C7 Corvette Diffuser Fins.
Great products!
"High Quality Corvette Upgrades with Excellent Fit"
Product is of excellent quality and design. The fit and finish is OEM or better. I purchased the front splitter, side rockers and rear diffusers for my C7. Along with the shelf behind the touchscreen and the rear license plate bracket. The product came in carbon flash metallic which perfectly matches the factory carbon flash metallic already on my Corvette. Product was packaged well to avoid damage . Product came in a timely manner. Installation instructions were good as were the online videos from the website Website was good to shop from, however it had trouble when I tried to set up my account, so I just ordered the product. This worked just fine. You get what you pay for. I've seen the cheap, ill fitting, poor finish, plastic junk on other vehicles that have come into my shop. I would definitely recommend your products to others. I plan to purchase more. I am a licensed auto technician and own my own shop. I expect quality. You delivered!
