Installed the grills today couldn't be happier. Really improved the front end
J.W.
Both the grille and downpipes were great fitment and quality. Best bang for your buck. Service was great. Downpipes cannot go wrong for the price look and fit great. The car with the new downpipes sound amazing, truly opened up the already amazing sound of the car. Had it tuned and it drives and sounds amazing.

Great product and very helpful staff! Cleans the look of the car.
Ronald Lorek Jr.
The wheels came out amazing. Was a little hesitant because of the lack of photos of different finishes and such, but the guys at GCA were super helpful and I got a rendering of the wheels before they started building them. I went eith the premium matte brushed 19x9.5+25. They were built to my exact spec for my S5. Not a bad deal at all for the price/quality, and you1re getting a wheel that pretty much no one else has. They also gave me the upgraded center caps at no cost which was a nice bonus.

Engineered with a performance-first mindset, GCA Performance ECU tuning redefines how your vehicle responds, pulls, and accelerates. This isn’t just added power—it’s a complete transformation in drivability. Throttle input becomes immediate, torque delivery is stronger and more consistent, and the entire powerband feels sharper and more responsive. From the mid-range surge to top-end pull, every part of the rev range is optimized to keep the car pushing harder, longer, and more efficiently. GCA Performance securely saves your factory ECU data, allowing you to revert your vehicle back to the stock settings at any time.
