Hi I was wondering if I could use H&R Sport springs on my stock shocks for my 2007 e90 328xi thanks, I just want it to look a little lowered

Be patient (if you don't have the funds right now), wait a little longer and save the $$$ to get shocks along with the springs. Or do a LOT of research on here (there are hundreds of threads) and read about every setup. Suspension is not something you want to sacrifice with this car. Trust me, you'll be sorry if you just change the springs and not get shocks at the same time. And you don't want to have to go back and do them later. Get it done right the first time.

And don't let someone do this for you. It's not complicated AT ALL. And if you're not happy with it or you end up with anything loose, you can do something about it yourself.

I'm on my 3rd suspension with this car and I'm far from a mechanic. I can't believe I EVER let anyone do this for me.

Thanks you are absolutely right. Thanks for the advice

I would strongly advise against just changing springs as well. The suspension is a system of parts working together .... the shocks need to be paired with the correct springs otherwise you throw it out of balance. I cringe at all the cars on this board 'dropped' on just springs.
Also read up on the XI suspension, it is not the same as the standard or sport suspensions on the RWD cars. Especially when it comes to upgrades.

OP states he just wants it lowered... so yes. HR springs on stock shocks will do the job.

I just did Tein S springs on stock struts, rides fine. It is apprx 20-25% stiffer but its fine. Just watch out for huge bumps like you would anyway. Got my Tein s used for $110 shipped and it sits PERFECT.

But FYI it will look more then just a "little" lowered. If you want a small drop and your not already on stock sport springs, either get a set of sport springs, or get Eibach springs. H&R and Tein will lower it a good amount.

Yes, the H&R sport springs will work with your stock shocks. However, paring up an aftermarket spring with more aggressive spring rates will cause your OEM non-sport or sport shocks to wear out over time. This is due to the fact that OEM shocks are simply not meant to handle the more aggressive spring rates. Think of it this way, you're putting a shorter spring with a longer shock body. The shorter springs will cause the shocks to compress to its maximum setting every time you hit a bump due to the longer travel distance. What this can cause is what's known as bump steer and jarring of the ride. This is what for the most part affects ride quality.

Let's break this down in terms of cost. You'll spend about $230-300 bucks for aftermarket springs, another $250-300 for an installation, and another $65-$125 for an alignment. When your OEM sport or non-sport shocks blow your going to have to spend another $700-800 on shocks, another installation fee, and another alignment. If you calculate that all together, you would saved a whole lot more mone5y doing it right the first time around. A coilver system is definitely going to improve the overall stance, aesthetics, and handling characteristics of the car.

As gizmo335i mentioned he himself had to go through this three times before he got it right. The XI models have it tough as there aren't as many choices available for suspension mods as the RWD models. One of the most popular choices is the KW V1 XI coilovers.
