Strut bar = biggest waste of money..

Well, that and the TRD springs.

 

strut bars do work, but less on tC than other cars. Unless youre into autoX or road course racing where chassis rigidity is tested, they are a bit of a waste on the streets. Sway bar (anti-roll bar/anti-sway bar) do NOT work the same as strut bars. Strut tower bars are TIE bars that just tie the chassis for a more solid feel. But the tC front strut tower is already attached to firewall so the effect isnt that great. As ConjunctionJunction stated, good tires are a very good investment.... costs $ but it improves pretty much every performance category. Good strut bars do not cost too much..... and it doesnt hurt to have 1.
