When my car is handling really well, but traction rolling, or on the verge of traction rolling, I try and remember what turns it happens at and slow a little more at that corner.
I would hate to compromise the handling to make it so I wouldn't have to slow down at the end of the straight, etc.
Now, if your rolling over in 3 or 4 turns, then it is time to look at chassis tuning, or radio settings. You can lower the car, lower the roll center(raise the inside link, etc), go to a softer spring, turn down the dual rate in the radio, stiffen the sway bars, etc.
The biggest thing may be tires, if your running M2, go to XTR, Red, go to Silver, etc.
Hope this helps?
