The car has coilovers as standard, so absolutely no need for lowering springs. The platform also suffers from a lack of wheel travel so be careful. Stiffer springs would make sense but at the same compressed length as stock.
My local dealership couldn't adjust stock coil overs so looking at other options…. When you say “platform also suffers from a lack of wheel travel so be careful” you recommend not lowering? Just trying to eliminate wheel gap Thx CKN
The 360 and F430 can be tricky to adjust because of the rubber spring pads. The trick is to carefully clean the threads of the damper bodies, and if they are really stubborn then you may need to take some pressure off of the adjusters by slightly compressing the springs (I did this off of the car). Use plenty of lubricant. Regarding wheel travel: yes, it's very easy to get to a point where the car bottoms out. It really depends on the roads in your area and any obstacles or inclines you need to drive over. The standard springs are very soft which makes the problem worse.
Well, if your local dealer couldn't adjust the stock coil overs then they certainly cannot install the springs for you if you were to get them. You can lower the car the same amounts with stock coil overs, or aftermarket springs. The ride however will not be as good with the stock springs. I do not recommend lowering the car and keeping the stock springs. Yes, they are adjustable, but the springs were not meant to be adjusted to lower it that much, small amount yes, but to get rid of wheel gap and give a lowered look, no. Can you? yes, just not ideal.
Always compress the springs before turning the spring perches or risk tearing up the threads on the shocks. If your dealer cannot lower your Ferrari with OEM coil-overs, find another dealer. Boardwalk can do it.
One would need to remove the shock/spring assembly when doing it, and compress the springs properly and do it off the car... It takes 10 -15 min to remove a shock...
I've had a good experience with H&R springs on my own ride. KW is another solid option worth considering.
