Not sure what benefit the roll bar will give. I quite like the bouncyness of the van and I certainly wont be driving it like a sports car. I assume it improves the cornering. Is that what it does?
That's the idea, the roll bars are larger and so the roll should be less pronounced. I've gone for them but tested without and it wasn't too bad. I have an XC60 which is no sports car, 235 x 17 x 65 so larger sidewalls..
