Hi Everyone, Can someone please confirm the spring rates for the F430 ? There are 2 tables which I found on the internet, and one of them is from StefVan (the table on the right) The Left table with spring rates circled in yellow OR the right table with spring rates circled in red ? Please click on the image below (it takes awhile to load the image, be patient): https://imgur.com/a/fWL5ZEd This is so misleading as I'm about to order shortened springs with uprated spring rates for my F430 Also, for your info, you may want to consider getting "SWIFT" springs as they are extremely popular as a spring upgrade for many aftermarket expensive suspension solutions. It is not so popular among the exotic car community for some reason. These benefits of these springs are: 1. The most consistent spring rate throughout the stroke 2. The largest amount of stroke 3. The highest durability against loss of spring height 4. The lightest in weight You can look up at more info from here: Advantage | Swift Springs USA I'm not promoting these brand, but I have used them on my other cars and they have transformed my cars totally.
Ferrari springs are grouped by spring rate when received from the manufacturer and marked with colors (red, yellow, white) to tell you which ones you have. Red is the stiffest grouping. I helped Stef with some of the calculations in the table. If you look at your springs, they will be marked with paint or colored tape to tell you which group they are. Ferrari fits springs of the same color group on each axle or car.
Assuming mine is marked with white. Can you tell me which table is correct ? The left table with spring rates circled in yellow or right table circled in red ? https://imgur.com/a/fWL5ZEd Left Table shows yellow spring rate is: 5.38kg/mm (FRONT) / 10.26kg/mm (REAR) Right Table shows yellow spring rate is: 10.2kg/mm (FRONT) / 14.41kg/mm (REAR) As you can see... the differences is a lot. One of the table is in correct. Anyone ?
I spent a fair amount of time researching this as I wanted to lower/stiffen my springs. I also came across the discrepancies in the tables above and after much digging created my own table - see below. I can't guarantee these are correct but I checked multiple sources. I was going to have titanium springs custom made to Scud spec by a specialist engineering shop but ultimately went for Novitec lowering springs. They are designed for the car and work within the shock absorber tolerances, they retain some of the compliance needed for the bumpy roads we have here in the UK, and they are progressive springs and so stiffen up under compression and thus limit roll on cornering as well as preventing the car from bottoming out on the road. Progressive springs are a compromise but these are a good one in my opinion. Image Unavailable, Please Login
