so does this mean these springs by H&R are good for normal/aggressive street driving and a lower look without having to mess w the dampers at all? or is this more of the usual putting a band aid on something that really needs stitches?

I test drove a new F30 328i over the weekend and still find the compression damping to be too much and rebound damping lacking. Installing sport springs only is not an upgrade, but rather a down grade performance wise. Coming from 14+ years in BMW suspension tuning...If going with springs only, struts and shocks with better valving is a must. Coilovers are usually match in terms of spring rates and valving so not only you get the looks you are after, the performance doesn't suffer either. |

Sport springs with oem struts and shocks are not a good combo. |

Springs are mostly for cosmetic and in some applications have some mild performance gains in handling. Doing a full coilover setup or matched springs with more aggressive dampers will always outperform stock shocks with springs

Sport (more modest lowering).

may be i'm too much of a skeptic ... but BMW develops F30 suspension for years including the friggin Ring ... and HR makes springs for it in 1 month? What are the chances this is half baked.. i'll bet it's gonna have a bouncy ride and most people will say "get coilovers instead"
EDIT: people above are already saying that...

But, if you do care about performance or the feel of your car through corners, swapping springs without touching anything else is not a great idea. |

People who can only afford to spend $1300 a month on a car. I can't speak for all, but most people in NYC drive cars worth well over $100K who wouldn't dare to even spend $600 on a single, affective performance modification so instead they spend $100 at a time getting typical modifications (black tails, tints, black grilles, black emblems, etc.) you see on every other "modified car" in NYC.

^lol
I'm sure all they need to know is whether the spring will fit the strut cup/plates, and the numbers are based on some formula from previous testing with older vehicles to calculate the spring rates. The improved handing statement is simply based on lower vehicle height, granted it's only improved to the point an amateur driver will notice. Ok that was all a technical guess |

Seriously?
It's funny how the same arguments happen every year for decades. We old guys figured out years ago that lowering springs alone ruin a car. Any theoretical handling gains from a lower center of gravity are far more than outweighed by the lack of stability when the dampers (struts, shocks, whatever you call them) don't have the ability to control vehicle motions in extreme situations. And then there's the overall increase in risk of bottoming out, which is a very real problem in the Midwest and Northeast. If you can't afford a matched set of springs and dampers and a proper alignment when you're done, for God's sake just leave well enough alone. BMW spent millions perfecting the F30's handling, and it's best-in-class. Why F with it? So you can creep around at 10 mph on your way to the mall? Go buy an SUV if that's your goal.

Nice! Can't wait until we get our hands on an F30!

looks great lowered. F30 just looked stunning in AW.
