Cheap products from China. They could be good, or they could fail spectacularly. I know I wouldn't take that chance.

You gotta be careful when they are so drastically priced that you can't even get half of a standard coilover kit for that price.

There is a slight chance that these are ok coilovers. A lot of the parts are made in china and ripping off some ones production run is pretty common now. Some of the normal brand coilovers are actually made at the same plant and just badged differently.

It's up to you.
Personally I wouldn't touch them since I actually track my car and having a coilover break while racing wouldn't be a fun experience.

Someone who never had coilovers before may get them, and will tell you those are the best coilovers in the world.. Someone who never liked coilovers, will tell you all coilovers are crap.

I say go for Megans as the bottom of the barrel coilovers.

I'd save for good ones. If you absolutely need suspension... Try them. Give us a review, and don't forget to mention when they break on you.

If the pic is an accurate representation then these are twin tube dampers, also there's no mention on what materials they use. Monotone are better for track and if the brackets are made of regular steel you'll never adjust them after they rust.

Megans are ok, I personally like Ksport Kontrol Pro coilovers, about the same price but they have an actual motorsports background. Just my $0.02

Monotube dampers use a larger piston design than what is shown here, I'd be real careful because it doesn't look like they're accurately representing the product. I could be wrong, but that's what it looks like.

All of the Chinese and Korean coilovers are crap. If you just want something cheap so that you can tell your friends that you have coilovers, then they should work fine. If you want actual performance then see this link:
http://farnorthracing.com/autocross_secrets6.html

Common entry-level competition-grade coilovers for our cars are the Koni/Eibach ERS kits from Mazdaspeed Motorsports Development and Ground Control, or the Bilstein kit from ISC Racing. Both are suitable for SCCA IT and EP events.

Only thing I don't like about ground control setups is that you can't adjust ride height without affecting travel, which is important. They're great for meeting class specs for certain race sanctioning bodies, but that doesn't make them the "end all be all" of suspensions.

My personal experience is as an owner of 1Gen and 2Gen RX-7s equipped with Mazda-sponsored racing coilover setups for over 14 years. While I may not be much of an automotive engineer, I did have help from professional Mazda race drivers and mechanics, none of which recommend that I put Chinese or Korean crap on my car. The ISC Racing setup is sold by a former Mazda IMSA Camel Lights driver who has multiple SCCA championship wins, and is one of the most respected Mazda IT/EP car builders in the country. The author of the "Autocross to Win" link earned multiple autocross wins and was the 1998 Grassroots Motorsports Magazine ProSolo Rookie of the Year. What is your personal experience?

Well please do us the favor of buying these for your car. Let us know how your experience works out.

I'm plenty content with my Stance GR+ and would recommend them to anybody looking for a entry level coilover. I would not, however, recommend buying no name suspension products regardless of how cheap they are. As they are load bearing components a failure at speed could put the driver's life, and others on the road, at risk. Not worth saving a few hundred dollars in my humble opinion.

These are MDU coilovers which are copies of Form And Function brand. No need to buy them to test them out just read here: http://g35driver.com/forums/brakes-s...coils-get.html
