I have an 04 5 a/t. I've searched around, and found a little bit of info. But would just a drop decrease body roll quite a bit? I was looking into sway bars as well, but the FSW sounds like a pita to install.. I'm not looking to make my tl into a race car, but hate that feeling around corners. If I do drop, I'm looking to get some tein coils.

 

a rear sway bar is one of the easiest mods to install and helps to get rid of that nasty roll.

 

What's the stiffest? Progress?

 

i'm going off of memory; because when i researched and installed the progress RSB, it was 3 years ago...

i think there's a comptech bar that is STIFFER than the progress bar. but I think it has been discontinued or something, not sure.

however, you really dont want to go VERY stiff, since you dont have a way to balance it out, ie: thicker front sway bar. (i think we have ruled it out because of its difficulty to install.)

the progress rsb is i believe 22 or maybe even 24mm thick..again i forgot. but once installed it does take the lean out of the car when cornering. and if you do set it up on full stiff, you will even get a little bit of 'lift off throttle oversteer' which is fun!!

 

The progress rear sway bar is 24mm. Since you have a base automatic run the sway bar on the soft setting . If you want to run it on the stiff setting you should get a type s fab or h&r front sway bar.

 

Alright, thanks guys! I'm going to look more into a FSB as it would help with the RSB. Can't wait to see how much just the rear helps!
