Customer photo review of 2014-19 Cadillac CTS Wickerbill Rear Spoiler

Cliff J.

I’ve ordered several items in the past. The quality is always excellent, shipping and handling is always free and packaging is very good. This was fairly easy to install with the linked video from Jet Fuel Only. I installed it on a 2016 Cadillac CTS VSport. It makes the car look more aggressive.

This is my second purchase with Extreme Online Store. Great products, best pricing and fast free shipping. Parts always come very well packaged and fully protected. The splitter goes perfectly with the factory performance pack front lip. It was a super easy 10 min install and fitment is 10/10, highly recommend!!

Customer photo review of 2022-Up Cadillac CT5-V Blackwing DRY Carbon Fiber Replacement Front Engine Cover

Dean B.

Perfect fit ! Just transferred the rubber mount bushings off the factory cover installed it and it looks awesome. Probably get an emblem for it in the future. I purchased one for my Gen 3 CTS-V a few years back from Extreme Online store and had to get one for a 26 CT5V Blackwing. Thanks for putting out great products at great prices.

Gary N.

It looks fantastic on my '17 GT. I assembled it inside in the a/c and my wife and I installed it this morning in about 30 minutes. The worst part is getting the old mounting tape off of the original wing. Get yourself a drill mounted adhesive eraser from Autozone. It's $40 well spent.

Great upgrade to the Sti with rocker side skirts. Really good quality and good fit. Really helps give the car a more aggression and wider stance profile. Happy with the results!

I'm 69 years old and installed these defuser fins in less than 4 hours. Pretty simple to install. Three of the 12 bolts a little hard to get to but I made it. They look great. Well worth the time and effort to install. They were installed in my garage with basic tools

Customer photo review of 2023-Up Acura Integra Extended Rear Spoiler

Alan A.

I didn’t know how I was going to like the new carbon fiber spoiler because I had bought the from Acura 2 1/2 years ago and it was smaller. The reason I bought the new one was because the one from Acura, the clear coat was chipping and peeling. And I wasn’t going to pay another $900 for a new one. Why would I if it was possible it may do the same thing again in a few years. Took it to a friend of mine to have it installed today. When I went to pick up my car, I was very happy. This spoiler is 100...

Matches perfectly! All of the holes lined up, no adjustments needed. The three pieces came together as advertised. So far my two modifications from EOS have been top notch. In the end you get what you pay for. Thanks EOS!

Customer photo review of 2005-13 Corvette C6 Z06 ZR1 Extended DRY CARBON FIBER Rear Splash Guard Mud Flaps

Rodney J.

I just added these mud guards! Very nice product! We had to cut a small plastic piece in the inside to get them to mount, but no biggie! I added these mudguards, a Splitter, side skirts, spoiler and rear diffuser. All EOS products for my 2012 C6 Grand Sport. I love it all! We took our time and did it all in like 3 hours.

Customer photo review of 2005-13 Corvette C6 Rear Trunk Lid Wing Spoiler

Stanley O.

This the best looking spoiler for the C6s IMHO. It matches all the body lines really well. The fit and finish of this product is great. They also includes 3M VHB tape for those who elect not to drill the outer holes, which is what I chose to do. The end product turned out so well. Highly recommend this for anyone thinking about adding it to their C6.

Customer photo review of 2015-21 Subaru WRX | STi Window Visors Wind Deflectors Rain Guards

Tom V.

Found a good video on YouTube to help with the install that shows how to put the clips in instead of the one on the product page which does not show how to put them in correctly. Definitely remember to put the clips in first! I forgot on the third one and it’s a giant pain to do after it is in, but still possible. :). They were shipped very well packaged and protected and look fantastic! A couple of extra bits and bobs included in case you drop one in the grass like me…. :)

Install was straight forward. I used screws on the outer parts of diffuser. Was easier than trying to thread the bolt with no space. Fit is great and love the aggressive look.

Side skirts fit perfectly, the screws sent were way too long so don’t use them!! Other than that the cf looked great. They were thinner than I expected, wish they popped out more.

Customer photo review of Corvette C8 Stingray XL Extended Splash Guard

Milton B.

I love the Black Metallic Finish. The fit is perfect. Installed was very simple. Delivery by USPS was a disappointment. I literally watched my box sit in Hayward, CA for days, once it started to move it sat in St Paul, MN forever. Order was placed on June 20, 2026 and finally arrived the evening of July 8, 2026. I would have paid for better shipping. The product is definitely A1.

This diffuser looks so good, the quality is amazing, install is fairly easy with two people but it just looks so freaking sick! If you’re on the edge about it just do it!

#16656 E.

I purchased the Z06 side skirts for the C8 stingray and was very impressed at the quality and the fit on my stingray. The install was very easy. My car had the stock side skirts and there is no comparison to the Z06 style skirts. This is the side rockers that it should have come from the factory. The price is very affordable and great customer service! I highly recommend them!!!

Jorge C.

I didn’t have the button in that part I of my c8 and every I look at it is like something missing. Dpi I order this part in carbon fiber and I think that it looks really nice. Very quality part.

The fit was very good, finish of the ABS was smooth and it installed easily. I recommend this product. Carbon fiber is nice, but overkill for use on a daily driver.

Kit looks great and fit perfect! The paint job on the pieces was very good and the carbon flash matched the GM carbon flash damn near perfect. Everything lined up how it was supposed to. Couldn’t recommend it enough

Love the gloss black, as it matches the rest of the vehicle and looks much better than the stock "faded" look. Had my detailer install in around 45 minutes and he said it was easy. A+.

Customer photo review of 2023-Up Toyota GR Corolla Carbon Fiber Front Lip Splitter

Johnson W.

- Product fitting was about 95% perfect, there is a corner on passenger side had a little gap after installation. - The installation was pretty simple, but I felt the additional crews that was given can be better so it really serves the purpose of adding on top of the manufacturer screws. I end up buying my own set of Stainless Steel screws, plus washier and nuts to fully tighten the additional screws besides the manufacturer screws. - Price was reasonable, so I really have no complaints for ...

Jackson K.

I wasn’t really expecting much when ordering this lip but i was pleasantly surprised when it arrived and it fit so well it lines up with factory holes in the front bumper (if you install with bumper removed) i was able to just nut and bolt install this rather than 3m tape or self tappers. i’ve had this exact design front lip but made by a different company but it was out of stock when it came time to replace it with a new one due to damage to the first one and i was worried about the weave of th...

Jeizome F.

Great meeting these guys at Corvettes at Carlisle. Had a good time chopping it up with them. My extended splash guards added a nice look to my C8 Z06. They are very well made and very easy to install. No need to remove the wheels at all. Will definitely shop with these guys again.

Brandon P.

Installation was easy and the wicker matched up perfectly with my OEM spoiler. Looks good and feels high quality. Worth the price. I did have to order new, slightly longer bolts to mate this with my spoiler.

Customer photo review of 2020-25 Corvette C8 | DRY CARBON FIBER Replacement Upper Dash Instrument Panel

William B.

I was having issues with the glue on my factory dash so I chose to do a full replacement of the drivers side with this beauty and it was well worth the money. Easily removed the factory piece with a trim removal tool and popped the carbon fiber piece in. It looks amazing and now my C8 stands out from others as you have a great look at it from the outside! Would recommend to fellow C8 owners who want something different

Christian E.

First off, I want to say Extreme Online is a complete pleasure to work with. I originally ordered the gloss black set & it didn't match the paint on my car at all (quality was excellent, it just didn't match as well as I wanted it to). So, I went through the return process to exchange them for the unpainted version. It was fast & super easy, Thanks Extreme! The quality is excellent & fitment pretty good. Price is cheap enough I ordered a spare set for when the day comes that I damage one or mor...

Customer photo review of 2005-13 Corvette C6 | ZR1 Front Side Wide Body Fender Pair

Nathaniel K.

Pretty nice upgrade, I installed them in about 3 hrs and took a grand total of 5 hrs to get the best figment on my C6 Grandsport. There is a tiny little nick on my passenger side near the headlight. I think it’s just a small defect, but unless your headlights are like mine you won’t even see it. I’ve never installed fenders before and found it pretty easy to do. Probably could’ve done it faster if I didn’t start at 8pm lol. Carbon looks stunning at night or in the morning and makes the body line...

My experience with EOS was great. It was a slight shipping communication where I was sent 2 of the the same headlights and they instantly sent me a replacement back in no time. I WILL be shopping here for the rest of my vette parts.

Customer photo review of Corvette C8 Models Z06 EOS Performance Track Style Side Skirts

Nick F.

I installed my new side rockers in my garage without a lift unfortunately. Installation was very easy and one person can do it alone. Everything lined up perfectly. Little apprehensive about drilling holes in my new car but they're located below the sight line, so no problem. The full length of these new rockers will hopefully protect the sides of my Eray for years to come. They look great in the carbon flash look.

Tail lights showed up much sooner that I thought they would so thumbs up for that. That packaging was perfect and the tail lights looked fantastic just in the box. Went on easily and when lit, they just look great. Such an upgrade from the standard lights they replaced. Would recommend to anyone wanting a more modern look.

Garrett M.

Install was much easier than expected, it fit perfect. Had an extra set of hands and it was done in 30 minutes. The gloss black is pretty much a perfect match for the oem black. Came with everything you need, but I bought a better quality 3m vhb for the install to be safe

This carbon fiber piece I ordered for my 2025 F150 Tremor fits my truck perfectly. The quality of this piece is extraordinary. Well worth the price and time it took. Makes the interior look and feel like a very expensive truck.

Chad U.

The spoiler looks great. I do think it would be nice to include a drilling template for accurate hole location. I also think different hardware would be nice the button head screws a difficult to use. I actually got my own hardware and got socket head bolts. Overall I'm very pleased with the finished product

Perfect fit. Got different tape (3M 5952). Can’t use the OEM hardware but that’s ok. 4 supplies bolt/nut and some 3M tape and doesn’t move an inch. Love it

I had a local shop install it for me. Took about 2 hours. Everything went smoothly. There was a chip in on the winglet . But nothing a little nail polish can't handle. Looks great, aggressive, and totally changed the look of my camaro. loving it so far.
