which sway bars i should get ?

ST ones (adjustable, little bit more expensive)
or Racing Beat ones?

 

I went with the ST non-adjustable ones from summitracing.com instead of the Racing Beat set. It really depends on what you want. I would have bought the set from whiteline.com.au if the shipping weren't so damn much. Otherwise these are real high quality units for a great price (AU$/US$ exchange rate is sweet for us in the states).

 

i got RB i heard bad things about ST

 

A bar is a bar is a bar. I got the ST because they bias the front to be stiffer. The RB make it stiffer in the back. I've had them in for a long time and no problems so far. The bars are good and the mounting hardware is very stout. They came with polyurethane bushings as well. I'm happy with mine. That Whiteline suspension link I posted above has a chart that can shows exactly the percentage in stiffness difference between different bar thicknesses. Good for demonstrating how much stiffer the bar is going to be.
