Need opinion Springs or coilver

Hi. I am thinking about drop my e93 335i (non sport pakage, 19" wheels). I dont know which way is better for me. Do i need to get just springs or coilover? If i just change springs, it may damage to OE suspension?
i drive my car every day for work only, no race. I want to lower my car just 1~1.5 inch.

if you're not going to track your car, springs are fine. they won't ruin your OE shocks...

Waste of money if you get coilovers and use it for just every day driving.

Coilovers are not necessary, but they do offer you the ability to adjust your height whenever you want. If you went with springs only you're stuck with the height you get, so make sure you get the right ones.

Koni Yellows are shocks that some people decide to use with the after-market springs of their choice. Koni yellows are some of the best. This would assure that you don't blow one of your stock shocks, as they are designed for use with after-market springs. Usually cost about 500.

If you want a drop of 1-1.5 inches I would look at the H&R sport springs or the Eibach Pro Kit, both of these springs are used by a lot of members. If you want closer to a 2 inch drop I would go with H&R race springs.

If I had coilovers, I would be adjusting them all the time.
My wife already gives me crap for the time I spend on the car.
I could only imagine if I had coilovers.

Coilovers are great if you need the adjustability and regularly track the car but for someone that mainly uses their car for street use and is just looking for improved handling and a lowered ride height, I would do a spring/shock combo like the H&R Cup Kit. If you have the budget, coilovers can be worth it due to their flexibility but for most, this adjustment is overkill. You would be better off saving the extra amount you pay for coilovers and going with a spring/shock combo.

for a daily driver, springs are fine.

I've never put coilovers on any of my cars, mainly because i don't track them often, don't need the adjustability and extra expense - just make sure you don't get too aggressive because with the lack of adjustment, if you want to change you'll be swapping the springs out.

I ordered a set of H&R Sports for my e92, the Race Springs give it a wicked drop, but for daily driving it's a bit too low imho.

You might also consider Koni FSDs for a more comfortable ride.

I disagree on going just springs.

Honestly if you are on a lease fine - get yourself some springs - because you are going to turn in your car in with some blown shocks at the end right, at $200 its a cheap solution to get your car lowered. (H&R sports springs would be my personal choice).

Now if you own the car, lets think about it - you buy springs about what $200 and install another $300-$350 what about the install that costs money right. Then 8 Months down the line (this all depends on the driver - I am considering a non track person who if he owns a BMW probably drives is spiritedly from time to time)- your suspension starts to feel stiffer and your shocks get worn down.

So now you have to get shocks $700-$800 (Koni FSD or Koni Yellows would be my choice) - to compliment those springs - again your out paying for the install another $300-$350. And are the shocks complimentary(in terms of valving) to the springs, not really. So you spent about - $900 on the springs and shock and $600 or so on install after that year, total of $1500.

I don't know your call but I think why not get a coilover like KW its the same money if you really put it into perspective (unless you do your install all this void). But one can pick up an ST coilover for $975 - and it comes with a lifetime warranty! It's springs and shocks are made to work with one another, you are getting proper arm length, so bump steer is in affect.

So thats my 2 cents on it, Lease = why not just get some Springs. Purchase - coilovers - enjoy your car and get yourself a great suspension setup.

How about coilovers? once i get coilover, is it no problem during few years or need to change something in time period?

Coilovers would be a complete spring and shock replacement and most coils are covered by a lifetime warranty so you would not need to replace the components later on. Let me know if you need assistance with a setup appropriate for your car

Does this warranty cover rebuilding the coilovers? I would give any coilover set about 15-20K miles before having to be rebuilt on a street car.

I recommend going with a set of KW V1s or KW V2s. The V2s will allow you to adjust the height and stiffness of the shock so you can really dial in the settings you are after.

Here is the link for more info on both setups: KW Coilover System for the E9X
