Also a reason the factory program only allows up to 25-30 MPH is... you’re out of alignment when you do this.I used the GAP tool to lower my 2011 RRS SC recently and it was a soft and bouncy as hell. Had to raise it again so not sure about the theories I am reading here.
What is the result (however slight) of the suspension geometry squatting, specifically when it is lowered? Does it appear stanced at all, if it were aligned at Normal height and subsequently dropped 20 mm?When lowered it is true that alignment is changed a little - HOWEVER - it is still within the standard tolerances.
When I last got my car aligned at -20mm before the alignment to suspension was still well within tolerances.
