Ok say I have a sway bar I could put in my car. Is it going to make that much of a difference if its only a few centimeters bigger than the one I already have in the car?

 

what size is the front / rear its good to have matched pairs.

 

ok well I had taken the rear end from this car and I switched it into my car and I swaped the sway bar with it and I was reading and found out the its good to have matched pairs so I went and grabed the front sway bar from the same car and put it in my car. have yet to see if it made a difference but now I'm on my way to the store so we'll see. Thanks for the help. don't know what the back one is but I found out that the front is now a hallow 36mm.

 

if your front is a 36mm then your rear is probably a 24mm. to take full advantage of these you need to use polyurethane or polygraphite bushings and end links to minimize deflection
