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?

L Lisa J. 2 months ago

Most of the carbon fiber stuff is just clear coated, not painted. Plastic parts are usually matte black unless specified.

L Laura Y. 2 months ago

I got a splitter in 'gloss black' and it came painted. Just check the description for the part you want, it usually says.

hey, was looking at a front splitter for my C7. how long does shipping usually take to like, Miami?

P Phil 1 month ago

Mine took about a week to get to Orlando, so Miami should be similar, maybe a day or two more.

C Cleo 1 month ago

i think it depends on the part. carbon fiber stuff sometimes takes longer to ship out. mine was like 10 days to texas.

what's the deal with returns if something doesn't fit right? is it a hassle?

T Troy Carter 2 months ago

I returned a side skirt because I ordered the wrong one. It wasn't too bad, just had to pay return shipping.

E Elena 2 months ago

Yeah, returns were easy, did it last month. Just make sure you keep the original packaging.

are extreme online store parts actually good quality? like, compared to other brands? i've seen some mixed stuff online.

M Mia Reyes 1 month ago

Yeah, they're pretty solid for the price. I got a spoiler from them and it's held up great. Fitment was decent.

N Nina Kim 1 month ago

I'd say they're better than some of the cheaper stuff on Amazon but maybe not quite Anderson Composites level. Good middle ground.

do their front splitters typically come with all the mounting hardware, or do I need to buy bolts separately?

C Colin Ito 1 month ago

Mine came with everything I needed. Pretty sure it's standard for most of their aero parts.

P Phil Y. 1 month ago

Yeah, all the hardware was in the box for my diffuser. You should be good.

thinking about getting that 10% off for first orders. can i combine that with like, a black friday deal later in the year?

A Alex Whitfield 1 month ago

Nah, usually you can only use one code at a time. Learned that the hard way lol.

N Nina Ito 1 month ago

Most places don't let you stack coupons, EOS is probably the same. You'll have to pick the better discount.
