Customer Reviews
Got my new side skirts
Just got the side skirts for my car and they look pretty good. Installation was straightforward enough, even for me. Shipping was quick, got them in about 4 days. Happy with how they turned out, car looks cooler now.
Good deal on mud flaps
I was looking for some mud flaps and saw Extreme Online Store had a decent price. Ended up getting a set. The cost was fair for what they are, and they feel pretty durable. It felt like a good value purchase for sure. Saved some cash compared to other sites I checked. They did the job.
Good rear spoiler, slow shipping
I ordered a rear spoiler for my Camaro and the quality is solid, really impressed with the finish. It bolted right up without any major issues, which was a relief. My only complaint was the shipping speed; it took almost two weeks to get here. Not terrible, but I've definitely had faster deliveries from other car parts sites. Overall, a good product for the price.
Detailed review of my carbon fiber mirror caps
I recently purchased the carbon fiber mirror caps for my vehicle from Extreme Online Store. The ordering process was smooth, I found the product easily on their website and the checkout was quick. They shipped via FedEx, and I received them in 6 business days here in California, which was within their estimated timeframe. The packaging was robust; the caps were well-protected in foam and a sturdy box, arriving without a scratch. Installation was relatively simple, requiring removal of the old caps and snapping these into place. All the necessary clips were present and strong. The quality of the carbon fiber weave is consistent and has a nice clear coat finish, providing a significant aesthetic upgrade. They fit snugly, with no gaps or loose points once installed. I had a quick question about cleaning the carbon fiber, and their customer service responded to my email within 24 hours, providing helpful tips. Overall, I'm very satisfied with both the product and the purchasing experience.

anyone know if extreme online store parts are pre-painted or if it's all just raw carbon/unpainted plastic?
hey, was looking at a front splitter for my C7. how long does shipping usually take to like, Miami?
what's the deal with returns if something doesn't fit right? is it a hassle?
are extreme online store parts actually good quality? like, compared to other brands? i've seen some mixed stuff online.
do their front splitters typically come with all the mounting hardware, or do I need to buy bolts separately?
