With the ratios, what version are you using lite or expert? Some screen shots of your issue will help me to understand how to assist.
Ride height is car and track specific, every car/track has a sweet spot. Race cars generally can be lowered maximum for flat and fast tracks, road cars would need around 10-20mm above min. I like to add a little rake (5-15mm) on most cars for added turn in and rotation.
I have the expert V3.0. I noticed with the SR3 Radical. I could setup everything besides the first gear. It showed me 1.4xx and the minimum was 2.122
