For peoples who say Front Strut bars don;t do anything haven't ever put one on a 93' Camry. Before i put the strut on my car as i would turn corners fast the tires would screeeeammm i put the strut bar on and the screamm was gone (NO BULL!) So that said, it may not give your "sport tuned suspension" much of a difference but i'm sure it helps.
Rear bar..uhhh can't help you there...
and the ingalls stiffy is a MUST!
regardless of my experience i would buy both sways and the ingalls stiffy.

 

maybe in some cars it helps but in our tc's it doesn't really maybe a lil but nothing you can feel. i have one and i couldnt feel a damn difference now when i put my trd sway bar i felt a big difference!

 

It's a comfort issue... Some people feel more comfortable knowing they have it...

 

That's it exactly, in some cars they make a much bigger difference than others. Cars that have strut towers furthest from the firewall benefit most, but the tC's towers are right there next to the firewall.

 

No kidding... It was a tight fit getting mine in there. Might not be needed but I like having it even if it helps only a fraction...
