Both equally road as bad and both felt like riding on a board. After talking to them I get that these are used in the vw scene alot just to get the stance but even they stated they ride fucking horrible. So you don't need to believe me and there obviously not going to post on here considering they both drive golfs. But go in vortech or whatever forum that vw guys regularly use ad they all love them cause there cheap and they go low.
not taking to heart at all I must have missed the part where you said it was a golf.

im just saying for verification, i have no problem giving an e90post member a ride if they are interested. Im hoping these dont ride like that lol i just hope the springs matched up with these dampers arent to rough, bouncy ride would be annoying of course. Im guessing the rebound on the dampers wouldnt be to great for daily but we will see.
Oh no worries dude for the price your lucky if they are built solid and don't break definitely can't expect good ride quality. I just hope for how much more solid are cars are the ride isn't that awful and atleast somewhat bearable. Good luck dude

I had BC coilovers on my STi... and as much as it was a pain in the ass to get them set up properly (hard to do on an inferior coilover), at the end of the day for a street car, they were not too bad.

However, for my sport package 335i, I think i'll let the stock sport suspension die.... then I'll spend the right money on a good set of coilovers.

Like stated earlier in this thread... anything that has a direct influence on the dynamics on the vehicle.... you do not want to fuck with.

Doing so just puts everyone else on the road at the same time as you at risk....

I don't know how the FSDs (or any other aftermarket shocks/struts that are meant for lowering springs) will work with the OEM non-sport springs. OEM sport springs are shorter than non-sport springs ( your car will sit ~1/2 lower with OEM sport springs) and are probably a better match. The drop is minimal and you will feel an improvement in the handling of the car.
Thanks Guys. I would have responded earlier, but have been having expensive car troubles since last week. My battery and IBS sensor went out last week, leaving me stranded and scratching my head because the car wouldn't start. Then, the day before my windshield wipers stopped working mid-drive in rain on the highway. After 2 days of grueling digging to see what is wrong, we found out it was the wiper switch and relay. Battery + Sensor + labor = $860. Wiper switch assembly = $540.

Wesley, thanks, I will consider your advice. I have seen certain sites that sell one's that are specific for sport and non-sport though.

going with koni fsd with zsp springs is a great option. it will absorb bumps better than oem yet sharper handleing. service life is around 40-50k miles and koni can be rebuilt. there is a reason why you dont see many koni products on for sale section and if they do show up, they get sold rather quickly. if you havent got rid of your run flat tires, that will change your comfort level day n night
Gotcha. I'll check out ZSP.

I really don't like the internal valving design of Koni FSD's and personally think they are a bit of a marketing product.

The theory sounds ok, but to obtain the ride comfort the damping is compromised in respect that the rebound damping in my opinion is too soft.

I've used Koni yellows and Eibach springs before on an E91and with the Koni's damping set at the midway position, the ride comfort was excellent. Really, really nice, on our bumpy roads!

Another advantage of the yellows is the ability to tailor the setup to your preference. If you fit the FSD's and find them underdamped, you're buggered, with the yellows, you can adjust until you're happy.

The yellows have also been around a long time and are a reliable well proven design which will last years. Again, if after say 5 years the damping softens slightly, you can re-adjust back to how it was.
I'll have to look into the price of yellows, thanks.

I'd be concerned with the integrity of the materials from a safety stand point. Good metal is not cheap. I've seen some no-name overseas spring kits and coilovers just crack in half.

What are the specs on the spring rates? Progressive? Ride Height Adjustments? Materials?

Honestly, for this much money you could have got a nice set of H&R spring and saved yourself the risk and money. (really not trying to hate but I really wouldn't trust those on my personal car).

I would just like to add. If these cheap coilover break or fall apart, it could damage your car, costing you possibly in the thousands to repair, especially on a BMW. Just something to consider.

Safety standpoint?

What exactly do you think can go wrong? Ive never seen a coilover crack in half. Maybe from an improper installation, but even the better coilovers have the same issues

Not only do many people use these, vendors who are more popular such as ECS sell these coilovers. Many group buys for other forums such as bimmerfest and vwvortex with no real issue and no casualties.

These are cheap, but you must have missed the point of not wanting springs. Ive had race springs ready to install but decided against it. springs are bouncy. yes they lower the car (non adjustable), but ride like crap and will sooner or later destroy my struts. No one has given me a real reason why these are "dangerous" or im putting my self at "risk". The coilover will blow before they explode . For 350, would i pick springs on 70k mile struts or these coils? id pick the coilovers. maybe i should have said 600 dollar coilovers.

i will check on spring rates as i would think they would be pretty high, linear springs it looks like, which coilovers aren't ride height adjustable?, im not too sure. they also come with a two year warranty!

Come on dude your so defensive your really saying what can go wrong and how unsafe can it really be besides a strut blowing. Man I won't even go into it about ride quality cause already have and I assume that really doesn't bother you but I did a quick search on the net and where they actually bolt up is has shitty welds and has actually just cracked right off while people were driving. Just looking at yours and the mounting point brackets they use they look cheap weak and are welded on not the best that's for sure

Bro... you praise these coils. you seriously would recommend them after seeing these? Also BC are made in taiwan, if anyone cares.

Thats just BC coils. Keep talking about how BC coils are the best. Even the best coilovers have their issues. With no experience with them how can you keep saying these are dangerous? Stop it. i can keep posting more. Koni coils, KW, etc. Just because you have a good experience doesnt mean everyone will. at the same time, if someone had a bad experience doesnt mean the product sucks.

Lol dude you are so defensive like you made these coils yourself or something. Never said BC were the best kid, but bang for buck they probably are and they don't ride like shit or clunk or creek around. You cannot even compare JOM coilovers to even any of the cheaper coilovers on the market so if you think BC KW etc are bad then the JOM are complete garbage. Like I said in the past here I hope everything goes fine for you with these coils good luck


I could do the exact same as you post 100 threads on JOM coilovers as well but I didn't see it necessary in this argument.

riding on a set of extreme drop kit bc coilovers with an additional 20mm shortened fronts and the swift spring upgrade for 12k miles now with zero issues and very oem like riding quality.

Also worth mention them i got them lightly used for under $800 with the damper extenders and new sway bar links and a few other extras, so as he said for money they are the best option. I may save the money on things like lips, spoilers, lights etc but never in a component as important and vital to your safety as suspension.

Thats great, but brakes and wheel & tire are more vital IMO. unless there is utter failure and i die; which i doubt will happen, i will document it.

these coils arent for everyone. Just like raceland dp, ebay intercoolers, replica wheels, china LEDs, ebay spoilers, etc.

If these coils provide a perfect ride height with a livable ride comfort ill be happy. I guess im the guinea pig for durability. Ill take them off if the ride is horrible or if see the coilover seized/rusts.

Im not saying these are the best at all, but why bash it? anyone can post bad and good reviews for products. No way am i saying kw or bc are a bad choice, but there are safety concerns with any suspension parts. saying these will just break is kinda crazy to me. These arent the only budget coils in the market or that e90post members use. megans have been used and like, but people still bash it because its not KW/ast/etc.

These are the JOM brand I believe, they are used by the VW crowd and I have read some pretty good reviews on them. Not the most comfortable from what I read but they work and will last as long as you dont dump the car. I guess the more you drop it the harsher the ride good luck dude.. i will be waiting on your results to pick me up a set!

Jesus Christ, Let the guy do whatever the hell he wants. At the end of the day him using cheap coil overs doesn't affect you at all. I just read 6 pages of non-sense...
