What to do about coilovers?

[LargeOrangeFont]

In the front the ratio goes from .5:1 to .9 to one, which I explained above. That's why you run a 375 up front instead of 600 and it still feels stiffer. But the rear is somewhere between .5..:1 and that goes to .6:1 with an IRS. Just to clarify what LargeOrange was saying.
To expand on another topic Orange brought up, mounting ears are a big deal. Maybe not so much on the sport dampers (reinforced to resist bending), but the MM2 and MM3 actually relocate the ears higher on the body of the shock as well as reinforcing them. This means more bump travel, and that's a good thing.

Yes I forgot that they (MM) lower the damper a bit as well with their housings. Generally speaking it is not an issue unless you have a really low car. If you are not bottoming out your stock struts, you won't bottom a revalved strut if everything else is equal.

Even still, fabbing a set up of front strut mounts is not a huge cost.
