"High Quality Corvette Upgrades with Excellent Fit"

Jim Hubert

| |

Ontario, Canada

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!

Wow, thank you for the detailed review! We're delighted to hear of your satisfaction with our products, it means a lot coming from a seasoned auto technician. We're sorry to hear about the trouble with setting up an account on our site, but we're glad you'll still be returning for more of our product. Thanks again!

Great Products, Straightforward Installs!

Luke Brophy

Pennsylvania, United States

As a regular dealer/vendor of ACS products I cannot recommend them enough. My customers love the look & fitment, my technicians love the straightforward installs using mostly GM components, and the proper hardware needed. Only downsides are the shipping costs & international fee, neither of which are ACS's issue, simply a factor of the industry.
