How in the world do I drive f4

I just to f4 after some brutal months of trying to get safety rating in rookies. I’m not a half bad driver but I just can’t for the life of me drive the f4. Like I’m decent but it understeers so much and the brake bias is so sensitive. I really need help on how to develop a good driving style for this car. Here’s what I have learned from watching the top 5 in my races, brake straight, trail into the corner, coast it through the corner, then get on the gas when you know for a fact that you aren’t gonna slide out. Help me please🙏🏻
