To GreyGoose006, as re: your post a while back:
No, 9C1 does NOT mean F41. 9C1 is a police car 'package', which likely includes the F40 heavy-duty suspension option --- which is DIFFERENT from the F41 sport suspension option... though there may be some common items for each of those two optional suspension packages.
This is a common misconception, unfortunately.
To renaldorae, I much prefer Delco stock, or Gabriel shocks over any Monroe.
