Jumpy cars on banked corners

[Toyauto]

Hello,

I have this problem that when I go highspeed through banked corners like Highspeed Ring or Speed Valley my cars start to jump all over the place, this problem is especially true with racecars.
I can solve it by setting up the car as a boat (loose shocks and springs and maximum rideheight) but I was hoping there would be a better way to solve it.
This is my first post here, though this problem is not just exclusive to GT1 but also GT2 (and perhaps other too) but I didn't know where else to post this.

it also happened on GT2. i noticed it when driving my Clio Sport 24V on High Speed Ring (which actually doesn't look like a ring at all to me) and at the last corner my car start to jump here and there and then i hit a MR2 because my car spinned out i don't know if there is other solution other than max ride height
