Best way to make your rig wider

[newtoy]

So after mounitng my battary to the front axel, changing my tires over to Rovers and adding wieght to the front my little redcat s10 climbs much better then my friends stock one. Now the problem is side hilling feels realy unstabel. So what is the best way to get a little more width out of your rig?
has anyone tried something like this

Have you added weight in your wheels yet? If you plan on using this rig for comps, then this may be a better idea than making your rig wider.

How wide is it right now?

i have added 3 oz to each front wheel i need to add some to the back as well. I am not sure i will ever compete and i think my rig is 12" wide. what ever a stock redcat s10 is

I can't see that kit making much difference to side hilling.

You need to lower the centre of gravity, either by adding more weight low down, reducing the weight up top, or lowering the ride height.
Softer springs might help, but I'm not 100% sure about this.
