Rounding off the sidewalls will actually make a car more prone to traction rolling. Keeping the edges squared will help keep the car level, but definitely makes it easier for the tires to chunk.
To keep a 12th from traction rolling, I would do the following:
- Ride height down to minimum (3-3.5 mm)
- Dope less of the front
- Softer side springs (AE Black in mod)
- Softer front springs will make the car push and not traction roll (AE .018 fronts, for instance)
- Glue front sidewalls
- Widen the front of the car
- Take out camber gain at the front of the car (long arm setup on an AE/VBC/Xenon front end)
- Add front brace if you aren't already running one
- Depending on the car, thicker tube lube can actually sometimes help keep it level. Thinner tube lube means the weight can get thrown to the outside, helping make the inside of the car lift.
I typically won't take out camber, but that is because I want the tires to wear flat. I normally find I can fix the traction roll through other items before even having to think about camber.
