E89 Lowering Springs
I have been thinking of doing some suspension work this spring as well as a custom tune and I was wondering if I could get some feedback from members that have just a set of springs on their car. I am leaning towards Eibachs at this point, but curious about H&Rs and others as well. I have thought about coilovers and matched suspension sets, and while I haven't entirely ruled them out, mainly looking at just springs right now. Thanks!

Just gave in H+R sport springs for adaptive chassis. They fit, the car body got very slightly dropped. Cannot share any (first) driving impressions as I havenīt ridden it yet (and wonīt do until April, though)

See my DIY Post-
DIY H and R Lowering Springs For 2009 35i Z4 This is springs only- No coil overs. Driving Experience: Better handling is an absolute benefit. Less body roll, feels tighter in slalom type, tight turns. Slightly harsher over rough roads running on my OEM Run Flats ( assumed) *Easy to install (*for someone with tools, patience and with good mechanical ability. My opinion-great DIY project LOVE the Low Look. Drawbacks: Cannot get a low profile jack under the front center jack point.- I have to now jack up the car from the side jack point to get under the front. No issues I have 2 jacks.

I really like my h&r springs. Looks and handling are improved as others have said. I would also suggest the front and rear sway bars, since you're doing the work anyways.
If track use, I'd splurge on a set of coilovers |

I've bitten my tongue and held this comment for years, but today is the day.
With no intent to criticize or disagree with another's aesthetic choice, for the life of me I do not understand the appeal of lowering the car. I certainly can see the benefit of upgrading the suspension for better handling on or off track, but the look of a roadster lower than it was designed to be confounds me. As someone with a design background, if you go through and look at iconic cars in this category like the Ferrari Daytona Spyder, BMW 507, Jaguar E-Type, or even more recent examples like the AM Vantage Roadster, Boxster or F-Type, you will notice a common, purposeful aesthetic choice amongst them all. The height at which they leave the factory is designed to create an even amount of space from the horizontal line at which the bottom of the body intersects with the tire all the way up and around the tire. In other words, if you look at the car in profile, you see an even amount of space between the tire and body throughout the tire's diameter. When you lower the car, the space between the body and the top of the tire decreases and the space between the tire and the bottom of the body increases, creating more of an 'egg' shape in that line. Every time I see it on our car or cars like ours, it sticks out like a zit on a supermodel. That's not to say I don't see the appeal on something like a '57 Impala, '32 Ford Coupe or other hot rod of that ilk, it just seems terrifically out of place on a long nose, short rear deck Euro-style roadster. Flame on. |

@ mbetoni: Sure, you got the point speaking of excessive drops (1.5" or more), but.... in my case (H+R sport springś for adaptive M-chassis) and speaking of the aestetics/optics/look - who says 0.75" of height difference?

As I said, it's all personal preference. While 3/4" may not bother some, it's something I'd notice and it would bother me. I suppose I'm picky

With apologies to Z4RIDER, and acknowledgement of his hard work (I read his write up and was impressed by the successful DIY), this is an example of a too-low-for-me drop:

Its all good.
Aesthetic appeal is all SUBJECTIVE. I KNOW SHE IS LOW. BUT as this is not my daily driver and driving experience/performance/handling/look/overall BETTER was my goal. Here are some photos of Pre H and R Lowered springs and (Pre- VMR Wheels) All due respect to the designers and various OEM measured heights as mentioned sometimes ( in my humble opinion) the designers do not always get it 100% right. Look at the tire/wheel to fender gaps F and R. The large 18 inch wheels seem to be somewhat lost in there. Do you prefer the tire to fender gap and being able to see the inside of the wheel wells or do you prefer the more closely spaced sizing of a lowered or MORE CORRECT stance to the car.

This I wholeheartedly agree with. The problem, of course, being the opening is designed to accommodate 17", 18" and 19" wheels, depending on how the car is optioned. Obviously, the 17" and 18" are going to feel more 'lost' than the 19".
I can certainly see that with a smaller wheel lowering the car is a logical attempt at minimizing that space. Makes complete sense. I have the 19" wheels and the gap between the tire and the car looks right (to me) with that size wheel. (And, as a mineral gray over red owner, please allow me to say 'I like your taste!') |
