501X cornering
 

when i take a high grip corner the inside rear wheel lifts off the ground :confused:

Sounds like you need a rear sway bar....

And the front is poss too soft, or shock oil leaked.

On high grip tracks, You can also put in some internal shock limiters. At the Belgian GP i used 6 mm in the rear and 3 mm at the front.

Picking up an inside rear view is not really an issue if the car handles. Is the handling unpredictable? If not, then I wouldn't be changing anything. Renaultsport Clio's pickup an inside rear wheel and they handle great!
