    Yeh I know it sounds strange, but I am over the bottoming out. Our roads just are not suitable here for a lowered 430. The diffuser and front valance have had a beating.
    So is it possible to crank the height up while the coil overs are still in the car?
    I know they come out to lower, but thought I would ask.
    I'm thinking maybe 15/20mm.
    TIA

    Yes, there is a spec range from the factory per model. At least on the F355 that I’m more familiar with Ferrari gives about 2cm of “in spec” ride heights.

    If everything is well balanced on your car you should be able to adjust each corner with the same number of turns and keep balance at a higher ride height.

    Thanks, while the springs are still in the car?

    Provided you're on OEM springs, they are coilovers. You should be able to spin the bases upwards with some grease and the proper base gripping tool with spring on (no load on tire).

    Helps if you have a spring compression tool to take the load off and, yes, while they are on the car.

    I may do the same, here in the UK they are putting speed bumps everywhere!
    I'd be interested to know how many turns of the adjusting screw equates to 1cm of extra height.

    Bear in mind you will have to adjust the camber and geometry as well

    Yeh once I have done this I'll have it all realigned.

    I'll take a note of how many turns and let you know. I am going for 15/20 mm.

    You may need to change the shim behind the lower arm, from what i am told the shock adjustment can be seized

    Do you bottom out if your in "Race" mode? I have found that makes a difference. If the suspension is "firmer" there is less of a chance of bottoming out. My GT3 at stock height but with an RS splitter is much lower than my F430 at stock height, but the suspension is much firmer on the Porsche and doesn't bottom out as often around town. My F430 really bottoms out in "Sport" so I never use it, but in Race mode is acceptable if I'm careful to take speed bumps at an angle, just not as good as the firmer and lower GT3.

    No it bottoms out in Sport as well. But having said that, our roads really are bad, especially the back roads anyway.
    If I drive like a nana I'll never have a problem. But this is a Ferrari and not a Camry!

    I've done mine as it was a pain in the ass in standard 16M spec. I've kept within the Ferrari rake spec and raised 5mm at each end. The F+R ratio is close but slightly different so I had less turns at one end to raise by an equal amount. I calculated the turns and it turned out nearly mm perfect.

    I have the luxury of 16M/Scuderia Delrin spring perches which are adjustable in-situ with a bit of lubricating oil. The F430 has rubber and they are a no-go without a compressor.

    I got tired of ruining expensive carbon undertrays and rear diffusers. Drive them properly and they bottom out at triple figures.

    What's the compressor for? I was hoping this was as easy and putting my car on my hoist and adjusting the springs with the proper adjuster tool.
    Maybe not.

    That's the crux of it, but if it has rubber spring seats then you must take the load off of them otherwise the spring perch will not turn. That's where the spring compressor comes in.

    Ahh. I'm half asleep, because I thought you meant air compressor!
    It's Friday....

    I recently raised my 360 and yes, I had to use spring compressors and the compressor hook tips had to be ground down to avoid galling the strut thread. The "hooks" were too long. Info on how many turns it takes for a given raise or drop is in the shop manual but using a ruler works just fine. Initially my cars tire tops were a little up inside the wheel well( sort of a hood slammed look) and now and have roughly about 11/2 finger gap between tire and wheel well margin. Clean the threads real well before turning up the springs and lube them with PB Blaster and/or spray lube. WD40 is not a penetrating fluid by the way. No more bottoming out.

    Thanks for this. I'll use a ruler and see if I can do this without wrecking anything. Are you saying it's OK to use WD40?

    He's saying that you need to remove the crud from between the threads and WD40 isn't up to it. He recommends PB Blaster and a spray lubricant..

    To clean the strut threads, I first sprayed them with 409, scrubbed them with a 1/2" round paint brush to free up the dirt and grit, sprayed with water and blew all the stuff off with compressed air. Then used brake cleaner(might have been carb cleaner) liberally on the threads and again blew the dry with compressed air. Then sprayed on penetrating fluid and something like Boeshield T9. The shocks and perches are aluminum so you do not want to risk galling the threads. I used two different size spring perch wrenches but you can just tap them loose with a brass punch and hammer but you will leave tell tale dents in the perch collars and anyone that sees it will assume that a dumb gorilla worked on your car. I used a small file to clean off the tell tale signs and then sprayed with black paint to disguise the gorilla work. Moving the perches without compressing the springs on a 360 is NOT the way to do it. Be very careful with the spring compressors. They can twist and pop off the springs so wear heavy gloves and watch the spring perch claws carefully to prevent them from popping off the springs. Good luck. You will love the ride once the car is lifted back to where it should be for driving on the street.

    Thanks man, and I really appreciate the tips. I hate using spring compressors because they always feel like they are going to slip.
    I might modify mine and try to get them to seat better. In the past I have used these compressors and they were OK, but the coil overs were off the car.
    Thanks again. I'll try to hide the inevitable lol

    You don't have to use a punch to turn the perch nuts. Ricambi sells the correct tool: https://www.ricambiamerica.com/lns-02-lock-nut-wrench-spanner.html

    That is the tool for the lock ring only. A larger version is needed for the larger spring perch. A couple of my perches were jammed together and using the Ricambi tool and a one tooth spring perch tool would not pop the perch nuts loose with out hitting the large perch with a punch. If a large version of the Ricambi tool was used on the big nut while using the small tool on the lock nut, tap one or the other with a hammer and pop the nuts apart with no dings. Soaking the nuts for a day with PB Blaster usually helps but who wants to wait a day for it to work?
