It is 22mm. And yes, 1mm makes a difference.Is it more than 21mm (OEM SVT)?
The reason they give you a front sway bar is to balance out the kit. Their rear bar is 25mm, and if you left the front stock, the rear end would be too loose for most. (however, there are some people that run the rear bar only for that reason)does the front sway bar make a difference?cause eibach makes both front and rears
