[BTT 335i]

Hello guys , I have a big doubt and hope that someone could help me, I have one e92 xi with wheels 20" not sport package, I wanted to change my suspension for coilovers kw1 but many people say that I am going to lose the comfort of the car and must not place oneself in a car of daily use, others say that if only I place h&r springs with my original shock absorbers I am going to damage the shock absorbers, only I it want to lower a half inch why the wheels are very big and I want that it beats, there might place spring that they come in the sport package with the original shock absorbers and not to lose the comfort of the car but I don't know much go down.
What I wish is to lower very little and not to lose the confort of the car.
If someone can tell me which is the best.


Thank you

BnG, just installed last weekend. Non sport shocks and the ride is smooth as butter. And I'm driving on Chicago roads.

Hi, you change just the springs or you change averything, shocks too, whit thats b&g system how much did you low the car?

If you pair aftermarket springs on your stock struts/shocks, you're going to blow them and then your ride quality is really going to go down the drain. If you only want a small drop, just get some lowering perches from SupremePower. From what I've read, they don't affect the ride quality in any way.

First of all, lowering springs will not blow stock shocks. They may cause stock shocks to wear prematurely, but not significantly.

Second, the front lowering perches DO NOT WORK ON XI vehicles, so that is not an option.

OP, chances are you won't like the ride quality with lowering springs on stock shocks, I know I don't - it's too bouncy. I've ridden in a car equipped with KW V3's and the ride quality was fine to me. Going with coilovers or matching lowering springs with an aftermarket sport shock will lower the vehicle and help ride quality. Ride quality will never be as comfortable as stock because the stock xi suspension is very soft and lowering the vehicle will stiffen up the chassis.

Whoops, I missed where he said that he had an xi.

And maybe aftermarket springs won't blow the stock shocks right away, but it will happen eventually.

Can anyone who has done this setup chime in exactly how the car will handle with after-market springs on factory sport suspension. Previous post mentions it is a bouncy ride?

Springs will lower the height of the vehicle, shocks do the absorbing. This may not be the best setup but how is it terrible? I've read here in the past this setup is strongly not recommended but I just don't see how. Eibach pro will drop it roughly 1.2 but since sport pkg is already .6 lower, the end result is about .8 inches. I would assume the shocks that come with the sport package are pretty descent and should be able to handle the change in springs. I did some reading on this a while back and I think someone mentioned once the springs are installed, the factory shocks are going to be in a compressed position and will compress more then it had to with factory springs when negotiating bumps?

I've got 65km on Ingrid, I will need to replace my shocks at 100km, I'm thinking of getting the springs now, drive on them until 100km, then get koni yellows.

Why don't I just do this now? Don't have the cash right now and my car is screaming for a drop (and spacers) and I love the tucked look.

you are not really correct sir.. just by putting springs on won't make you blow out your shocks. It will cause them to wear out a little quicker and shorten the life of them by a few months or so. Not something that will be a problem for you in the near or not real distant future.

I am also riding on B&G's with stcock sprot shocks and like hajduk said "the ride is like butter".

anyway, if you keep the car long enough you will have to replace shocks eventually anyway. At that time you can get some that are more capable of handling in differences in the spring rate.

I think what you want to do makes perfect sense to me. if you are going to be replacing struts in 30k km anyway, go ahead and get the springs you won't regret it. I wouldn't rcommemnd going with spacers that are too wide because you may rub in the back, unless you get the fenders rolled..

[Boosted John]

i just noticed that you have 20"s.. how wide are your rear tires? i have 265/30/19 on the back of mine and i rub smoetimes. aslo my wheels are basically flush with my fender. I think the spacers will do more harm than good and also will make your tires stick out too far.. just my 0.02 worth..

Eibach by nature is a more conservative drop and not nearly as high of a spring rate as H&R. If you already have sport shocks, the ride probably won't be terrible. However, why pay for installation twice? It'd be one thing if install only took an hour and set you back $75. However, it's a 3-4 hour install costing at least $200-$400, plust at least $100 for an alignment each time. I know you're trying to save money but, take it from a guy who knows first hand, it's not worth it. Do it right the first time.

while were are discussing
what what about using a lowering perch with the stock sport springs, what damper/strut would be ideal?

i just don't think you would get the drop that you are might be looking for...
as far as wearing out the struts a little faster, I'm not really sure about that.

Would your opinion change if there was no installation cost? I'm lucky to have a good friend who has lowered every car he's owned and is able to do the install with me. Thanks everyone for your input, I think i'm going to proceed with this, along with spacers either 15 or 20 rear and 10 or 12 front. Hopefully I can have it done this summer.
