So what are the downsides to sway bars, I think a while back I heard something about the new handling of the car becomes a bit to aggressive maybe? But before then I had only heard good things about rear sway bars and people saying they had no downside. Most of my driving is on highways, so im usually going 70mph if that helps at all in whether or not I should get a rear sway bar.

 

I guess the downside would be oversteer, which IMO is better than understeer. It takes practice to get used to the handling, but I thought it was worth it.

 

Get an FSTB too to go with it, if you don't have one already.

 

I just ordered a FSTB a few days ago.
