Perfect
These are hands down thee!! Best budget coilovers. I’ve purchased many different brands for my drift/daily cars and the only other good ones were TruHart. These are still on my cars today 7-8 years later zero issues in WI through all seasons. Great quality and a great value. They fit perfectly and are very durable.

Excellent Bang for the Buck
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.

Budget coilovers, failure at 50,000 miles
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.

Camber plates are painted and won't hold camber.
I mean, look at this camber plate. It is painted, and that means the washer head is going to dig into the paint. It will never hold unless you remove that thick green paint. The oil pressure dropped in one week, so put them higher than expected for the first two weeks. Check your camber plates after installation and driving. I noticed mine after a week. The camber dropped me lower aswell, so, be careful with those two things. I'd recommend getting your own camber plates and coils, and choosing a strut to put them on, recycle the old springs you'd like. However, getting your own camber plates on top of a 60 to 100 dollar strut with stock or lowering springs seem to be the be the solid choice. Painted, f'ing, camber plates.

First to review??
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

Dites-vous que ce quitte est une aventure. Mais peut-être pas une bonne aventure. Déjà le manque d’instruction, l’omission de dire qu’il va falloir absolument un camber arrière, Ça parler de trois ajustements sur quatre qui ne fonctionnait pas à l’arrivée . Vraiment, faites vos devoirs avant d’acheter
