S class X-Bow tune for Circuit de catalunya school circuit

Im trying to tune a s class x-bow for catalunya school circuit,ive been working on it for hours now and im getting a little frustrated,

The 3rd corner on the circuit has a little lump to it which is causng my car to have negative to positive to negative G-force which is causing my car to wash out and skate at the rear,im wondering if theres anything i can do to lessen the g-force effects and make my car more stable over the mn bump ?

The track is the normal circuit not reverse.
Any help pleaseeeeeeeeee its annoying me

Thanks.
