help with heights

for elite driving but the height works the other way around, that is, the more you lower the front the more it rises because if you put like 34 40 the car slides on the curbs while if you do 33 38 for example on the curbs the car goes well? why not do a detailed guide to help us make customized setups? And never before someone answers you seems like a million dollar request
