Anyone know if i'd see a reasonable difference in the body roll and handling with just a sway bar installed, but no drop. Im not really feeling like spending the money for springs and struts right now. But I'd like to upgrade the handling somehow.

Mostly want to take car of the roll when entering curved freeway onramps and turning.

yes you would, sway bars performance is not contingent on lowering springs.

i believe you should feel the difference. more so with springs/coilovers, but still..... better than stock. What brand are you looking towards?

Not in the tC, I haven't installed mine yet, but in my Civic there was a huge difference. I didn't have the car lowered either.

As drax said earlier the affects of a stiffer sway bar, front or back, is not lessened by having the car higher.

Installing suspension, making the car lower to any extent, is going to greatly help reduce body role though, so as a package you would be better off doing both. Lowering the center of gravity my friend.

It will help.

The TRD sway was my first excursion into scion handling. It's a huge difference that's immediately noticeable.

Yeah I'm looking toward the TRD sway. Ive also looked at the progress one, but its weird because when I search for it, I've found a 22mm and a 24mm. Maybe I'm mistaken, but either way I cant find the 24mm for sale anywhere.

Other than that I havent really decided, Im on the fence with it all since it'd be about 880 to buy the struts springs and sway and get them installed (all TRD). Which I think is a good price, but none the less not cheap.

It will def. improve your cornering by a mile. My car's not dropped (sadly up until now :( ) and afterI installed my TRD rear swaybar------heaven! Totally worth it! And get the front strut tiebar too for added stability (though the rear gives a more obvious improvement).

I got front and rears, but I believe for the sake of normal driving, you really only need the rear. After you pull out the stock one, you'll immediately know why we have such massive understeer (which is good for beginners unaware of a car's abilities) because the stock rear sway is friggin wimpy. Front helps stabilize the car in my opinion.
