XRAY - Model racing cars

Had a problem with the high speed sweeper at the track. Was told to use the -.75 roll center in the front suspension. Will this work? What else could I try?
Someone else said that if the rear diff was too tight that it would cause lack of steering.

This thread had a similar question and the replies helped cure what your describing as well.

Hello,

-0.75 roll center will give you more steering into the corner but does not solve on power push. If you want to increase cornering speed, lay down rear shocks into second position from bottom, use 1.3 rear anti roll bar, put 2.8 springs into rear shock, and rise the rear roll center by +0.75. All these set up changes will give you better cornering speed and solve problem with on power push.

Will this make the rear of the car loose

Yes, little, always when you want to increase on power steering, you decrease rear traction. I would try all these combinations to find balance between steering and traction
