Hi everyone! i want to know the difference between rear bilstein b6 dampers for xsara, zx and 306, the code should be 24-060608 for the xsara, 24-016247 for the zx, and 24-020749 for the 306. i read that standard zx/xsara dampers should be harder than 306 but i can't find any info for the bilstein. if possible i want to know also if there is difference length between the three dampers or there is only a different setup.
