Front suspension difference (318ti vs 323ti)
 

Hey all,
I was wondering if anyone could tell me the difference between front suspension (shock absorbers and springs) from a 323ti and a 316i/318ti M sport suspension. There doesnt seem to be a M sport option for 323ti.
Are 323ti OEM shocks shorter that the 316i/318ti ones?
According to realoem.com, 31311090715 is the part number for front left shock M sport for 318ti and 31311091269 is the part number for front left shock from a 323ti (only option available).
Thanks in advance!!
