Dude the S-Techs are real nice!! They make a HUGE difference in the way it drives. the turn are nice and tight, i dont get much roll from what i can feel. i really grip to the road on turns, i took a turn at 75 and i hung on real good.
Your going to pay arm and a leg for all that TRD parts. you pay even more for the TRD than any other brand out there just about.
I prefer most of the aftermarket parts more than the TRD, however the only upside is warranty with TRD.
S-Techs give 2.4 front and 2.0 rear drop. the TRD give 1.5 all around...
If you don have any serious problems with your car, keep it and start doing stuff to it, if you buy new one, you'll be too strapped to do anything to it.
I got 61,000 miles on it.
I bought it a year ago and it had 24,000 miles.. lol.. I LOVE TO DRIVE!!!
