Evening all, just researching some stuff on suspension. I've got 2.8 Bilstein front legs on my capri, but i fancie upgrading them, so i've been looking at getting either some 260/60 or 300/70 inserts, now their Group 4 fitments. What's the difference between group 4 and the capri legs? If i.m right the diameter of the insert as it goes into the top mount is larger, but is that all?
Thanks
