If I was to put a anti roll bar underneath my car would I need just 1 or 2?

It is a rear wheel drive car. Thanks.|||That is completely up to you. Most likely your car does have a stock anti roll bar in the front, at the least. You have the option of installing an anti roll bar on the either the front or the rear of the car, or both.





Some people like different feelings for different vehicles. It depends on your preference and driving style. Personally if you aren't too picky, beef up the front one a little and install a good thick rear say bar.|||All cars are already fitted with anti roll bars.|||Just one will do da thing|||You already have one in the front, unless maybe you're driving something like a 58 Chevrolet truck.





It certainly makes a difference in handling whether you beef up both ends. This is really noticeable if you have a stiff bar on the rear and not the front. Ideally, you need "big" swaybars on both front and rear.|||That depends entirely upon the kind of car and what you are trying to achieve. Different types of use will require different setups.





In other words, we need more information.
