the body roll actually reduced quite a lot, when normal driving, body roll reduced around 40% i think.
when car over bumps i feel firmer, and actually that is improved too.
so for performance side, it really improved
but the problem is when driving on normal road or high way, the car never stop "shaking" or very soft little jumping, which i said like "on boat feeling" and dizzy. in the other word, it's feeling 10 times more road feeling. same on the uneven road, bumping up and down. or feel like the spring rate too high that shocks can't control it. but i think the f sport shocks should be enough?
which i didn't expect that..i just want to improve the ride comfort.. i don't like the factory setting as they are too soft i feel. i just want to firm up a bit (feeling similar to european car) and also reduce the body roll. so i'm thinking maybe the spring/shock set isn't good? because maybe different technology or something? i'm quite comfusing now. have you tried f sport spring+shock set? is that feeling more like a european car or somthing else?
oh and one more thing, when normally close the door (not hard pushing), i can obviously see the car shaking.
