The 550 has threaded lower spring collars that will permit a bit of lowering without changing springs. You need a shop with an acurate alignment rack and a savvy technician. I beleive the service manual even gives the motion ratios so the tech knows how many turns down on the spring collars yeilds how much chassis lowering. If one just goes down the same number of turns both front and rear, they will upset the rake of the chassis as the front and rear motion ratios are different.
For example, the Ferrari 348 front ratio is 0.70 and the rear is 0.85. So, lowering the spring collar 0.70 inch in the front and 0.85 inch rear lowers the chassis one inch and maintains the relative ride height front to rear (known as chassis rake).
The collars move 2mm for each complete turn, so in the above example, turn the front 8.9 turns and the rear 10.8 turns down.
You can measure the ratios on your car relatively easily if the manual does not have the info.
Lowering will change camber and especially toe settings, so an alignment is necessary. If you forget the number of turns you've already done on the collars and get confused, you will require a set of scales to reset corner weights. If you pay attention and take notes, you won't need the scales, assuming Ferrari set the car correctly from the factory, which they usually do. |

Isn't the suspension on the 550 quite low already? If you lower it more, aren't you going to have problems clearing car park slopes, driveways, etc. (especially in HK)? |
