Shock Towers

[GripGreg]

Hi Guys
I know that, in some cases, the larger the number the smaller & visa versa.
In the case of the spring rates, are the springs from a '75 stiffer than on the '80 FAQ or not??
I know that Petr Frac or whatever his name is, had it in his mind to be better then the Mercedes 280.
I already found the cold air intake is better in the '75 compared to the later E12!
Also, do the springs from a '75 fit over the '80 shock towers? I'm planning to upgrade to the vented rotors of the '80.
Thanx ln advance,,,,Greg

It appears that the early E12's had very similar spring rates to the later E12's. It is in the middle (1977 to 1979) that they were stiffer. I have a 1977 and a 1980 and the 77 definitely is stiffer.
