Interchangeability between models

Was playing around on eurospares & scuderia parts website. It's wild how many parts are interchangeable between the models. For example 299933 is the rear hub and it's shared between 458 series cars, FF, Cali and F12 series cars (this means SP1/SP2 as well).

259687 is the P/N for the rear upper control arm and it's shared amongst the above models AND the 296 & Roma as well.

In retrospect it makes sense given the low production of Ferrari that you'd parts share as much as you can between models and across time but it's still wild how the same part is used across nearly 5 generations worth of cars (depends on how you're counting generations but from an 08 California to a brand new 296/SF90 I'm counting that as 5 generations)

 

It's wild how much the boxster/cayman shares with the 911 since inception and yet the general public and even enthusiasts still believe the boxster/cayman is somehow "less than" the 911... from the firewall forwards the cars are effectively mechanically identical and even from firewall rearwards there's a lot of parts sharing and compatability

There's really nothing "wrong" with parts sharing when looking at a company like Ferrari which makes historically less than 10,000 cars per year. If all the cars have double wishbones and multilink suspensions ...why not share the arms/hubs given all the cars are roughly the same size/dimensions. A good camber curve is a good camber curve and you can fine tune that on the subframe mounting points while retaining the arms/bushings/hubs across models. You then tune the damping rates and spring rates to suit whichever car. Clean and efficient.

On porsche it feels a bit more lazy though given how many 911s and boxster/caymans get sold every year. You'd think at that scale, model specific design would be a given but nope, there's as much parts sharing in the 992/982 generation as there was with the 996/986 generation. I guess that just makes the boxster/cayman extremely good value given you're ACTUALLY getting more or less 911 stuff at a steep discount.
