Sport springs on stock strut.

Already searched if you guys are concerned and only found h&r and stock strut.

Is it possible for me to put OEM BMW sport springs (my car is the basic version) on my non-sport strut.

And also what is the difference between shock and strut. And what does BMW have?

In theory you can do that but why not lower it with H&R. Nothing will happen just wear out your shocks faster.

Honestly don't make the mistake go with coilovers. I have H&R sports on oem shocks and they are stiff. Ride quality especially with the 19s I have is horrible. I have 18s for winters and those are awesome. I had 20s and lets say that wasn't a smart idea.

Truthfully, I hate lowered cars. I like it stock out of the factory but I want the sport because of the little more stiffness.

If you don't want low I'd go with BMW Performance suspension or dinan suspension. Very minimal drop with great handling improvements.

Why is that? A "tastefully" lowered car I think enhances the look, with some minimal ride degradation (if done right). I'm talking about say, just over an inch. "Stanced" cars on the other hand...well that's an acquired taste. At a car show they're interesting and look kinda cool, but on the road? What's the point in having a performance car that you can't go over 60 with? I lowered mine about 1.4" and it's a bit stiff, but not a board. Just my 2 cents man.

OP if looking for a nice suspension for that sport feel go with H&R sport springs you'll enjoy the feel and the lowering isn't that noticeable unless your a bmw enthusiast. I just did mine and it feels great car looks way more aggressive and feels way sportier.

Actually if you are not interested in lowering, but areinterested in better handling, you should be upgrading the struts/shocks instead.

In your shoes, I might try it if:

my dampers already had some miles...say, over 50k.
I bought the springs used at a great price.
I do the work myself...and can take them off myself if the ride doesn't seem to work out.
if this is the case,
if your dampers wear out a little earlier it's not a big deal...and you will already have the springs when you change out to a sport strut / koni / etc.

Edit
to answer your last question, BMW has McPherson strut up front and a shock in the rear. Spring goes over the strut, in the rear, the spring is separate from the shock.

If you or someone else are doing the work, it's less labor to do both front strut and related spring at the same time. Not much difference for the rear.

I'm guessing, since you asked this question, you won't be doing it yourself...you might be better off doing both struts / shocks / springs at the same time.

h&r sport for the win! you can use stock shocks with any springs, just a matter of how long they will last till you need new ones.
