Quick question for anyone that might know. I am planning to install the STB on my 2005 FX45 as soon as grubbs gets more in stock, and I have just started looking at installing the eibach springs as well. My first question is does the STB raise the COG on the FX at all? I take corners pretty hard and and would like to know if this is the case. I know the springs lower it, which leads me to my second question. I plan to take the FX on road trips and might max out the cargo space, would installing the springs mean that the car would be riding on the rear bump stop with a moderate load in it? Thanks!
