    • Definitely the best option even compared to the OEM!

Review Image by Manuel De León Manuel De León
Now these are some goodies! I’ve been looking for a good, reliable and cost-effective option for a suspension kit for my 06 Civic. I’ve seen good reviews on YouTube and Amazon about these Rev9. Let me tell you guys that (in my personal case) these are as good as they seem and more! I use my car for daily drive, for work (20-25 kilometers everyday) on highway and city, sometimes I take hill roads with some bumps and I carry my family with me, and for every situation these work as a charm! They’re precise, comfortable, adjustable to my needs in height, durable, easy to set up and guess what, they cost almost as much as a new OEM kit for my Civic! Definitely the best investment I’ve made so far. 08/08/24 Update: 2 years running on these goodies and they still rock like the first day! No regrets at all! I hit a pothole some months ago so bad that it broke my front right strut mount. I called Rev9 and explained the situation and I got 2 new replacement mounts. I replaced them myself (I'm not a mechanic or sorts), installed them back and just as new! I love these and would definitely buy again. Thanks Rev9! ... show more

    • Mixed review - seems good value but some issues to resolve
Size: 2006-2011 Civic all trims
Review Image by Lee S Lee S
The car is a 2010 FD2 Honda Civic Type R (Asian market). I am a club race car driver with some expereince with many coilovers. This is my first time trying Rev9. These bolt up for the most part but there are issues: Cons: the lower bolt holes are small but fixable and the car ends up with a serious negative camber as seen in the image. IT is fixable with a camber plate (not supplied) but the vendor is not responsive after. I am not satisfied with the product support. pros: On the plus side, the ride feel is good. Compared to stock suspension, this is a bit softer but that is not a bad thing. I will test the adjustable rebound settings if the vendor solves the camber issue. the shock absorbers are height adjustable independent of the ride height. This is an excellent design feature. This product is capable of 5 start especially for value if the issues were resolved. ... show more

    • Good coilovers
Size: 2006-2011 Civic all trims
Overall these are great for the price. I ran into a few issues during the install. First, these came with absolutely zero instructions. While I don’t need step by step instructions on how to take my car apart a set of instructions on how to set preload and a general measurement for ride height would have been helpful. Next was the front coilover assembly. Since these were already fully assembled I figured all I needed to do was set the ride height. After I took it for a test run I noticed something up front sounded loose. The nut holding the assembly together was only finger tight. Maybe this was my fault for not checking but I guess I didn’t think to check since it was already fully assembled. After all that I still think the Rev9 coilovers are one of the best value coilovers on the market. ... show more
