    • Double check the preload!!!! If set up right they feel great! Ride great
Size: 2012-2013 SI ONLY
Review Image by Jeff. D Jeff. D
9th gen Si sedan /Don’t be an idiot like some other people and have the damping set all the way up for normal street driving with pot holes. Smooth track only. It’s plenty Steph around 15-20 clicks for every day driving And you won’t blow the shocks. Do some research and learn how to set these up before you put them on. There was sticker one each strut saying that front struts are preloaded from the factory, mine were completely different like a big difference. Also check the studs mine were sliding out. Other than that I have no complaints for what I paid there’s nothing out there like this quality for the money. 60 day review, still ride great no leaking struts or shocks. Very happy. 1.5 years later, blew the left shock. Over loaded the trunk with weight and had the rear to stiff. The front still going great. Replaced the rear shocks and still has great ride quality. Very pleased with these coil overs for what I paid and it’s my fault the shock blew in the back. ... show more

Got them installed today. A little tough to get the height right but worth the time. Replaced an old set of Skunk 2 shocks and springs and the ride is night and day. Less road noise and no creaking or clunking. Ride is a little bouncy but nothing I can't handle. Rears don't go as low as the front but I guess that's to be expected. Overall a nice setup for the price. ... show more

The media could not be loaded. Ok I was a little worried when I bought these there weren’t any reviews. But they looked bette then the competition and affordable enough to not brake the bank. The reason these caught my eye was the notch that holds the strut on the tower brace. As you can see the old ones I had didn’t and they slipped threw. I have them set at OEM ride height right now until I can fix another issue on the car but these boys can SLAM!!!! I had a picture of the new ones compared to the old side by side but I can’t find it. The picture showed that even in the front they can go by far lower then any eBay coil over. I ride my with full hard dampening and it feels like a brand new car. I couldn’t be happier with them. So far haven’t given me any trouble but I’ve only been on them for about a week. In my opinion they are solid ... show more

    • Budget coilovers, failure at 50,000 miles
Size: 1996-2000 All
Ordered these in April 2022, installed in May 2022 for a 99 EJ6 (4door ek). Pre load needed adjustment because none of them were the same out of the box. Adjustability of these are nice and they do ride quite well. After roughly 15,000 miles I was getting a clunking noise from one coilover in cold weather. I found the top nut was backing out, so I had to tighten that nut to rid the noise. Now approximately 50,000 miles and 2.25 years later one of the coilovers started getting a harsh clunk, upon investigation I found that same strut is now blown out and oil is leaking everywhere out of it. I'm sure there is no warranty so I'm just stuck with having to replace them on my own dime now. I was curious how much life I could get out of a sub $500 set and I found out. They fit the vehicle appropriately but Maybe I shouldn't expect so much out of aftermarket parts. Update, after removing the suspected failed coilover it appears the failure is caused from the shock canister coming apart internally. Which is what I was hearing before I would tighten the top nut. So this failure is a result from poor assembly quality. FYI, a new canister is $175 or a new coilover assembly is $275, not worth it. ... show more

Within a month they were completely blown. Cheap parts quality wise, not cost though. I expected a lot better paying the price I did, and will never recommend or buy them again.
