Customer Reviews
Fast shipping, good product
I ordered a front splitter for my Camaro. It arrived quickly, took about 4 days. The part fit perfectly. No issues with installation.
Amazing front bumper lip
I just received my new front bumper lip and I'm so happy with it! It completely transformed the look of my car. The quality is fantastic, feels very solid. It was easy to install too, which was a huge plus. My car looks so aggressive now. I will absolutely shop here again for more parts. This store is awesome!
Carbon fiber spoiler review
I purchased a carbon fiber rear spoiler. The quality of the carbon fiber was impressive for the price, and it looked great right out of the box. Shipping was a bit slower than I expected, took 9 days to reach Denver, but it was well-packaged so no damage. The fitment was mostly good, though one of the mounting points needed a little persuasion to line up perfectly. Customer service was responsive when I inquired about the shipping delay, which I appreciated. Value for money is definitely there, just be prepared for a potential slight delay and minor fitment adjustments.
Decent side skirts
Got some side skirts for my car from here, and they're pretty good. The installation wasn't too bad, just took a bit of time. They look sharp once they're on. Kinda wish they had more color options, but the black works. Overall, I'm happy with them, made my ride look a lot better.

Trying to get a new spoiler and a diffuser, can I use two different coupon codes at checkout? Got one for signing up and another for a holiday sale.
Hey, thinking about grabbing a splitter for my Challenger. How's the fitment usually on these EOS parts? Worried about gaps or having to modify stuff.
Looking at their front splitter guard. Is it really worth it or just cosmetic? Does it actually protect the splitter from scrapes?
How long does shipping usually take from Extreme Online Store to like, New York? Need a splitter for a show in a couple weeks.
Anyone know if EOS parts are actual carbon fiber or that fake stuff? The prices seem a bit too good for real CF sometimes.
