No pissing contest here, but you are hitting the jounce bumpers, you might not be maxing them out and running out of shock travel, but at -1.25" you are there.
To add to this post, a while later.
I have had the enjoyment to have a few conversations with several team members about this very topic, and many pros and cons. Probably much to their dismay I keep some notes to myself, because I really enjoy the dialog. So here are some facts from the people that built and designed these cars that we love.
The car with 2 people at 175lbs each, has 40mm before hitting the beginning of the stop (1.57"). So using this, with occupants in the car, there is approx. 5/16" left before the beginning of the bump stop. Note the bump stop is not a bottom out, and a clunk. There is a non linear compression. Initially its about 3 times the spring rate, then rises to 5-10 times, before bottoming out to solid.
Also your spring rates are not changed, the lowering kits simply change the perch, and reducing available travel.
There is nothing wrong with the lowering perches. The give a great option to lower the car and the look desired for a modest price. My only point in participating in this thread, is to provide my experiences, and to now provide info on the trade offs on a lowering kit.
