Spring rates for Euro 328

Haven't come across any printed 328 spring rate specs myself, but I have noted that, not only are they different part numbers for US vs euro 328, they are different part numbers for 328GTB vs 328GTS -- so you are going to have to get even more specific about B or S

 

The parts book indicates that springs were the same for all markets but were changed with the new suspension VIN#76626. Shocks were changed with the new suspension and then again with VIN#78613 which roughly translates to 89's again same for all markets. Early GTS US cars have a spacer. The later cars have a spacer for US, Swiss and Saudi cars apparently both S's and B's. No indication of spring rates but anyone who owns a 328 knows they are pretty soft.

Really? -- Then how do you explain this SPC data from Ricambi that shows different front spring PNs for US vs euro non-ABS 328:

I don't know. I'm just quoting from Ferrari's own publication which often has different parts for different markets but most parts are universal.

Which "publication"? Is it a publication restricted to a single-market?

I'm sure that the spring differences aren't large, and, later in time, F will often substitute a common part for parts that used to be different; however, even the later '89 328 SPC still shows a difference between the US and euro non-abs 328 front springs (even though the B vs S distinction has been dropped):

Spare Parts Catalog 1988 (although there are 1989 parts in it). The book itself is part # 95990259. It is in multiple languages and includes parts for all markets. Mine is a Mar Parts reprint of the original factory publication. There are errors in it. One of the more glaring is a listing and illustration of parts for a hydraulic clutch for 1989 cars but none ever had it.

I believe the (1988) abs 328 SPC at Ricambi is the same publication. Does your Table (Page 42) not show multiple market entries for the front spring like this?:

What PN does it show for the spring?

My guess would be that the US-version springs result in a slightly higher ride height just to meet some minimum headlight-to-ground US-required spec.

 

My bad. I was looking at the rear suspension and didn't check the front. I think your theory about ride height is a good one but the springs are the same from 76626 up and no spacers in the front while US cars have spacers in the rear.
