Anti-roll bars, in doing thier jobs of resisting body roll, they also increase the load on the outside tire. which, given the way tires make traction, means that there is a Net reduction in the total amount of traction that end of the car can make (the end with the stiffer anti-roll bar). So... in some cases, it may be advantagious to reduce the effectiveness of an antiroll bar. Such as on the front of a FWD car.
Smaller would be the way to go...
