We installed the Hellwig sway bar Saturday... WOW! Now to be fair, I've been driving with NO sway bars for a while now... but the thing is I NEVER had a rear sway bar! 2005 V6 coupes do not have rear bars... they weren't even an option! LOL!
The improvement in the cars handling is stunning! Can't wait to see what happens with we get some good tires on! And some better shocks... LOL!
