    Hi guys,

    This is long over due, but here goes.

    I saw a deal for a budget coilover from a company called Rev9 for the crackhead price of $476 shipped from Redline360, a vendor here on the forum. There didn’t seem to be any reviews online for the 10th Gen Civic so I decided to take a gamble.

    If you want to know if these are worth the price, I’ll get straight to the point: These coilovers are exactly what you would expect for the price. They’re pretty stiff, the fronts won’t drop the car as you would expect from any other coilover, and the finish quality is very lackluster.

    The verdict is this: If you’re not looking to slam your car, and are okay with a very stiff ride over stock, I’d say these aren’t a bad buy.

    Update 4/9/19:
    Don't buy these. Rear shocks blew already. Waste of time to try and get any kind of warranty or your money back, see my post below for more details.

    That’s the short answer.

    If you’re sticking around for the full review, let’s start from the top…

    I’ve gambled on coilovers before. When Megans first came out, I bought them. I felt they were fine. I’ve had D2’s before anyone was really rockin ‘em, they too were fine. I've had even the most basic Teins and they were also acceptable.

    I’d rank these coilovers just right below everything I’ve mentioned and right above Raceland, and any other eBay coilover.

    First off, out the box the powder coat was already chipping.

    This means that over time, the finish is probably gonna wear off faster and rust or corrosion can be an issue if you ever need to adjust these things later. They’ll probably get stuck.

    Next, (and this is my major issue) these don’t really give you the ability to lower your car all that much. In fact, when I first got them, with the pre-load adjusted properly and the shock body set to the absolute lowest setting, it was STILL ALMOST AT STOCK HEIGHT.

    For comparison, this is the vehicle when I purchased it at stock height:

    Here it is with the proper preload set at the LOWEST setting up front:

    That’s just not acceptable for a coilover, especially when they claim that it’ll lower the car up to 3 inches. That’s just not true.

    You can technically get it lower if you bottom out the spring collars as well, but the ride would just be so unbearably bouncy and unstable that you'd be a road hazard.

    I sent this info to Redline360 who graciously worked with Rev9 to get me a shorter shock body. The one they ended up sending me still wasn’t much shorter than the previous one...but an improvement. Furthermore, based on that feedback Rev9 said they would be pairing the shorter shock body for every 10th Gen Civic coilover they produce going forward. Here's a comparison for what they sent:

    So at least that’s better for anyone making that purchase going forward. Being completely honest, I still think it could be at least one inch shorter and that would be perfect.

    Anyway, with what they sent me I was at LEAST able to set the pre-load correctly so I wasn’t bouncing all over the place while allowing my car 1 finger gap from tire to fender all around. I imagine that’s about similar to the Eibach Prokit springs. For the record, my plan never really was to slam my car, but when buying a coilover you SHOULD have the option to.

    Here's where I ended up:

    The last thing, as I stated before is the ride quality. The spring rates are a little on the high side so that’s just going to result in a much stiffer ride. You can set the dampening of the shock to be softer, but the ride doesn’t really bother me that much.

    The bright side to all of this is the perches ARE pillowball mounts, so that does put them a cut above a lot of the most basic eBay brands, and the price is...well, it’s cheap. Personally, I don't think the gamble paid off for me and I will most likely be upgrading to another coilover within the year. They just don't drop low enough for me.

    Hopefully this review was helpful.

    Here's an interesting follow up. From the time I wrote this post until now, the rear shocks blew completely. I had to go back to the OEM shocks, which was fine since they are separated. The car rides much better now, actually.

    Upon contact with Rev9 through Redline360, Rev9 won't warranty, replace, or refund anything despite the horrible experience I've had with these coilovers thus far. They did offer me better pricing on a replacement, but why would I bother to throw money at a problem that was created by the way this product was designed?

    They said that I adjusted the shock body on the rears way too low, which is why they blew. You can see them from the unboxing in the photo above -- thats how they came out of the box.

    I don't remember reading any specifics in their instructions on the proper setting for my application, and last: Why would you even add an adjustment on the shock to begin with if you know any setting beyond a specific point will blow the shock?

    My guess is because they just have a bunch of random parts that come together to create a product for a specific application. Which is understandable in how they can cost so little.

    I'm going to eat the cost on this little science experiment and let you guys know: Don't buy these.
