Some of you have read my Koni + Gymkhana thread and appreciated the measurements and photos I provided.
I am going to do the same now, but I'm going to open an entirely different can of worms...(You can click on all images for larger versions).
When I was building the setup, I took the time to measure the bump stops, and amount of strut travel you would have before you encountered them. The front bump stops measured 2.25" and available strut travel was 4.25":
I went out today and measured my static ride height (F/R: 14.375"/13.370").
I then used the distance in between the rim and the fender to get an accurate measurement of how much droop travel I have (5.125" static, 9.125" at full droop = 4" of droop travel):
So looking at the amount of strut travel available at full droop (4.25") and the amount of droop I have from static height (4"), you would assume that I have .25" of travel before I hit the bump stops...that's close, but not quite.
Because the wheel is mounted at the end of a lever (your control arm), and the strut is mounted farther in, 1" of wheel movement only equals about .97" of strut movement (Note: .97 is the only ratio I could find online, if you have something more accurate, please supply it!). For my 4" of droop travel, this is only ~3.88" of travel at the strut. And 4.25" - 3.88" = .37" of travel before the strut hits the bumpstops.
At least I am on Konis and can add an inch of bump travel easily:

This is not too bad, but what about folks that are lower?
JdmGary is on P1 springs, and noted yesterday that his ride height was F/R 13.75"/13.25"
This makes his droop travel 4.625" and inner strut travel 4.48" meaning that his car is always sitting ~0.23" on the bump stops, or basically...just touching them.
This leads me to believe that most lowering springs are really acting as helper springs for the bump stops and that the bump stops are really doing all of the work...
I don't think this a good thing... Are these springs designed with this in mind?
I know that the stock suspension is dependent on the bumpstops as an integral part of it's function, but I'm not sure these bump stops were designed to do more work than the actual springs that are installed...
