Is it not possible to approach this from a more technical perspective rather than requiring a test vehicle? I can speak for myself but I certainly wouldn't want to be the guinea pig for springs.
Shouldn't this be more about understanding the spring rates on the stock Q4 system and seeing if these lowering springs are actually applicable? I imagine these lowering springs can be installed (hope this isn't an incorrect assumption) but the concern is what is the impact to ride quality in soft and firm on the adaptive dampers.
With the spring rates / numbers I would hope we could speculate what the ride quality would be like.
Our MADNESS springs are manufactured in Germany and have been engineered to pass strict T.U.V. certifications for safety.
These springs were designed to fit the 2.0L model and should work well on all 2.0 models. We also have a specific set up for the Quadrifoglio Model as well.
Each one of these springs is different in design and have different rates and lowering thresholds. The springs for the non Quadrifoglio models lower the vehicle approx 35mm. The springs we are releasing for the Quadrifoglio Model drops the vehicle approx 25 mm. Both were designed to work properly in each application or else they would not pass T.U.V. certification.
Any time you are installing lowering springs on a vehicle ride quality will be slightly compromised. However, with this kind of a drop and the design of the Giulia suspension, ride quality is really not that big of an issue.
To give you an idea we are currently running prototype springs with a set of 20" Custom Vossen Wheels. We have 30 series tires in the front and 25 series tires in the rear and the ride quality is still good with no complaints from those that have driven the car or the numerous passengers that have ridden in it in the front and back!
Hope this answers most of your questions and concerns and as we get more of these springs installed we will post additional pictures and feedback!
On a related issue with Q4: what about fitting lowering springs, then installing an Airlift 1000 kit inside the springs in order to be able to lift the vehicle up when the snow gets deep? Will the springs tolerate being "stretched" that way? With this heavier than optimum system the air pressure can be used to determine suspension height and there is no chance of a suspension collapse due to an air leak and there shouldn't be a significant change in spring rates.
Hey Lockem
We don't really encounter too much snow down here in TX!
That sounds like something that is much more custom then a simple bolt on set of lowering springs.
If that is something you would be interested in doing give us a shout and we would be more than happy to work with you on it.
We have a custom Toyota Sienna Minivan as the family hauler here at the shop and we have designed and installed a fully custom airbag suspension on it controllable by your phone. It is a daily driver and has logged in over two years of service with zero issues!
This spring set up is a pretty common, easy upgrade that should work very well for most. For the few that want something really custom we can certainly go much further. We do custom project vehicles pretty regularly at our two locations. Maybe we will post up a separate thread sometime in the near future giving some an idea of some other custom rides that we have had some fun with.
