If your budget is tight then springs are the way to go. Even though most people i know eventually end up either changing out the shocks as well or go with coilovers.

Everyone here will say save until you can afford coilovers. It'll save you money on labor.

However I lowered my car with springs first and later found a great deal on used set of Koni Yellow.

Best inexpensive mod: Koni FSD's.

Shocks / springs must be matched or your ride will be degraded - FSD's are designed for stock springs. Figure ~$1k - DIY install not diff.

If you buy coils with camber plates that come preinstalled already, then DIY install will be simple, just a matter of remove and replace.

Can the FSD's me matched up to the stock non-sport springs?

For a daily driver that gets driven in snow/salt, I've heard that coilovers can corrode.

The video embedded below should help with your decision on if you can handle the DIY or not. Honestly suspension work isn't that difficult as long as you have all the tools and plenty of time.

Well yes and no. Coilovers such as the V1s, V2s, V3s from KW or the Stainless Series from FK are made of materials such as stainless steel which is resistant to corrosion from the elements. Your entry level coilovers such as STs don't hold up quiet as well in heavily salted areas due to the materials they are made of.

But how many companies out there make a complete strut assembly that doesn't require you to transfer the top hat on the front suspension? Name a couple please..haven't really seen one yet.

Thanks for the clarification. Also, thank you so much for the DIY video. The last time I changed springs/shocks myself was on my 1987 Mustang 5.0 back in 1997. I've got the tools and the will, now with the video I have the information to do my 330i myself. Save me money and quite frankly gain a sense of pride. Thanks again.

I was one of the ones that went springs (B&G) > lower springs (H&R Race) > coils (K-Sport). All springs will work with your factory struts but the lowering height levels will determine how the ride quality is. The ride quality with B&G was GREAT

Jumping inside this discussion. It seems that when changing shocks, one has to buy new bump stops, and a variety of other small hardware. Since a good set of coils+shocks is marginally less expensive than entry coilovers, a set of ST (as an example) may be the money conscious choice ?

mainly, the $1000 price ranged coilovers: Megan, BC, D2 etc.
