Customer Reviews
Detailed review of rear diffuser
I purchased a rear diffuser for my vehicle. The ordering process on the website was straightforward, and I received an email confirmation right away. Shipping took about a week, which was reasonable. It arrived well-packaged with all the necessary hardware included. The quality of the ABS plastic was good, and it seemed durable. Installation was a bit tricky in some spots, mainly aligning all the mounting points, but it ultimately fit well. It definitely changed the car's aesthetic in a positive way. No issues with customer support as I didn't need to contact them.
Good front splitter
Got a front splitter for my car. It arrived quickly and was easy to install. Fitment was spot on. Happy with the purchase, made the car look better.
Ordered a front lip
I ordered a front lip spoiler last week. It shipped out pretty fast, got it in about five days. Installation wasn't too bad, mostly just bolted right up. Looks good on the car, gives it a more aggressive vibe. Overall, a decent experience.
Love my new rear spoiler!
Just installed my new rear spoiler and it looks amazing! The carbon fiber finish is perfect. It totally transformed the back of my car. I'm so happy with it. Will definitely be ordering from here again!
Consistent quality with side rockers
This isn't my first time ordering from Extreme Online Store. I've bought a front splitter and a rear wing from them before. This time I got some side rockers. Just like my previous orders, the quality is consistent. They arrived on time, actually a day earlier than the tracking said. The fitment was as expected, no surprises there. It's why I keep coming back; I know what I'm getting.
Great value on side skirts
I was looking for some side skirts and found them here. The price was really good compared to other places I checked. Felt like I got a solid deal, especially for the quality. First time buying, and it was worth it.
Extreme Online Store Community Discussion
Share tips, ask questions & help fellow shoppers save more
Anyone know if I can use more than one discount code? Like a first-time buyer one and a Black Friday code?
How do Extreme Online Store splitters compare to, say, ZL1 Addons? Is the quality similar or better?
Saw a 10% off code, but I also want to get a bundled aero kit that's already discounted. Can I stack the 10% on top of the kit deal?
Do their front splitters usually come with all the mounting hardware, or do I need to buy that separately?
Is this Extreme Online Store place legit? Like, real company, not some drop shipper with fake parts?
