    So with the last few lowering threads it got me thinking about a question I really haven’t gotten a good answer to before.

    If you use lowering springs which are not linear like the H&R springs will you actually prevent the front from scraping because the suspension will not compress as much and the car will actually raise more when going over a bump in the real world?

    I know when I had my Boxster S way back when (20 years ago) and I put on lowering springs the car actually scraped less in the real world. Are the 360 and f430 like that? I know people say the Scuderia scrapes less than the f430, could that be more about the stiffer suspension than the slightly different bumper?

    Just looking for some real world experiences.

    Thanks,
    Cheers,
    Corey

    My 360 spider was lowered by a previous owner. Looks nice but I do bottom out more frequently than others.....its funny when people running behind me, say the car blew sparks or something...I just grin.. the cost of hauling a$$. I've replaced the bottom pan once just because a friend got a new one and gave me his which was in somewhat better condition than mine. I have also had the front fenders rolled as they were catching on the tires....HTH

    Do you know if the car was just lowered on the stock springs or were progressive lowering springs put in?

    I don't consider my car lowered, I consider the delivery height 'raised' or lifted.
    Ferraris heritage is race cars, that's how they were designed and engineered... See the 430 challenge.
    Unfortunately, they are lifted as a compromise for street use... Not even specific to your area but likely the upper average of all roads/ramps.
    I returned my car to the Ferrari designed height (or as close as I can practically drive in my area.) The roads are great we're I live in fl

    I have not scraped, but I am very used to low cars. There are many places you simply can't go. Even shallow ramps have to be taken at a diagonal.

    But it's more than worth it over the compromised 4x4 height IMO

    Don't know if any universal unit will work.

    Won't work without modifying the coilovers (due to OEM design), and will need a airtank and noisy aircompressor that takes up half of the front compartment.
    Hydraulic is almost silent and takes less space.

    Stock ride height = less head aches.

    I think most everyone is not getting the point of my original question.

    If you lowered your car with progressive lowering springs do you bottom out less than just lowering the car with stock linear springs and simply lowering the coil overs from original height?

    Bottoming out under what conditions? Going over speedhumps/driveways/etc? I’d say no it’s not gonna to make much (any) difference. The chances of scraping will be simply based on how low the car is.

    I lowered mine with shorter springs. Still bottomed out and bent the shock flan blocks. Replaced the stock springs and raised it back up to Challenge height and now not bottoming out. Ride seems less harsh as well. I suppose I am getting old and the lowered look is no longer important.

    I’m pretty sure progressive rate springs are softer k factor for first x% of compression then progressively higher k factor ie stiffer… so I suspect you will bottom out more often w progressive.

    If you have fixed k factor stiff springs.. it will take more force to begin compression.


    This assumes things like ride height and rates being equal.

    Are they add on lifters? I was under the impression they were entire suspension setups to replace the factory

    Yes.. They have a kit for OEM coilovers and they have a kit for their own coilovers for F430.

    I installed air cups on top of my oem coilvers. It gives me 2.5" of lift, which is just enough for steep driveways, etc. I also upgraded to Swift Springs with a slightly higher spring rate. Zero complaints.

    Could you elaborate on your air cup setup?
