I’ve fitted lowering springs to the following:
Peugeot 309 gti -just springs ran for 2 years no issues (still running now after 15 years)
Saab 9-5 - just springs ran for 3 years no issues.
Saab 9-5 aero - springs, shocks, stiffer anti roll bars no issues in 3 years of ownership.
Alfa 159 - springs and poly bushes no issues for 5 years of ownership
Lotus esprit - pro tech springs and shocks absolute rubbish. Then lotus sport 300 springs on avo shocks absolutely brilliant. Most difference made by the springs.
ghilbli -springs wheels and tyre dimensions no issues to date.
Lowered springs will change the at rest point in the shock however they also have a different spring rate which shortens the travel. I personally wouldn’t consider changing the shocks if lowering between 20 and 30mm. More than that and you have to decide whether to go further. My ghibli is on the H&R 35mm lower springs and needed larger wheels and tyres to stop it from scrapping (original wheels were only 18”).
Car will need the tracking checking and realigning depending upon the amount lowered. I personally don’t think that any part will fail any earlier than it would of in the first place.
To mod or not to mod is the same argument in every car forum. There are equally as many people that are advocates for it as there are nay sayers. Usually modifications only go badly when they are done excessively cheaply or by people who don’t know what they are doing (DIY and some garages). If in doubt either take it to a reputable garage for their opinion or don’t do it.
My ghibli is a 65 plate and was scrapping speed bumps on the original suspension and 18” wheels plus I was sick of it wallowing around corners and so from my perspective it was worth changing the springs and alloys. I class shocks and bushes in the same category as brakes and tyres (service items) If I need to replace bushes or shocks in the future then so be it as at least the car handles and looks the way I want it to and from what I can tell Maserati parts are not always the most reliable even on a good day.
Other considerations are warranty, insurance, value, lease options etc. which I would argue are more important and likely to cause bigger issues than the mechanical aspects.
If you are thinking about doing anything to your stelvio then I’d recommend talking to Ned at autolusso. He is based in Houghton Regis in Dunstable, Bedfordshire and will be able to give you impartial professional advice, options and costs.
Well put.
I think I've only owned 3 cars in my life that I haven't lowered. Nissan GTR (it just didn't need it), and two GranTurismos. The first I think needed it visually, but I know I would have regularly scraped on my local roads. The second (current) one, has the MC-handling pack (Strad suspension) so is a little lower and Stiffer from the factory, so is just about OK visually and manages to still not scrape much and handles very well for such a big car.
I would say with lowering springs, that are generally a bit stiffer, you may wear your bushings a little quicker, but whether it be by a noticeable amount, is just guesswork.
Lowering springs on standard shocks wouldn't worry me at all. As said about it just moves the working position a little, and a shock is designed to work over its full travel.
Lowering by 20-30mm is no different to having a couple of passengers on board.
If it'll make you enjoy your car more, just do it.
Just get the geo set up afterwards, or you'll wear the insides of your tyres quicker.
