Customer Reviews
Consistent quality as always
This was my third order from Grand Garage Tuning, this time for a Carbon Fiber Trunk Spoiler. Like my previous purchases (a shift knob trim and some fender vents), the quality was excellent. It arrived well-packaged and the finish was flawless. I appreciate that their products always fit well, it saves a lot of hassle during installation. Delivery used to be a little quicker, this one took 6 days to get to me in California, but it's still reliable. It's why I keep coming back; I know what to expect.
Nice Carbon Fiber Mirror Caps
I got the Carbon Fiber Mirror Caps for my car. They look really good! Installation was pretty straightforward. Took about 4 days to reach my place in Texas. Happy with how they turned out.
Good product, minor shipping delay
Ordered a Carbon Fiber Front Lip Spoiler. The part itself felt solid and looked like real carbon fiber, which is always a plus. Fitment was decent, no major headaches there. Shipping took about a week, a bit longer than I hoped for, but it arrived safely. I think they could improve the estimated delivery times on the checkout page. Overall, a decent purchase for the price.

Anyone ordered from Grand Garage Tuning before? What's the shipping like to California? Trying to figure out if I'll get my stuff before a track day next month.
Hey, thinking about grabbing a carbon fiber spoiler from here. Anyone know if their parts are, like, actual real carbon fiber or just some hydro-dipped plastic stuff?
