Is there a site or any help to install suspension for the tC at all? Any help is better than none.

yeah, i used that site like years ago and it was decent. a couple recommendations if you're changing the stock springs...

1. have an impact wrench/air compressor(used for the center nut on the struts and shocks). you need enough torque for this to come loose or else the top mount plate will keep spinnin if you dont have type of vice clamp.

2. go rent the spring compressor at kragen or autozone(free)
they'll charge ur card and return ur money after u return it.

3. do not let the hub drop too far cuz it'll pop out the axle and u'll be in a _____ of a time. this happened to me n a friend last week doin his RSX, thought we were careful but it happened somehow. Never happened to me on scions.

4. TORQUE wrench to make sure everything is torqued correctly.

If it's your first time, give yourself like.. 8 hours

some of the bolts will seem like they are threadlocked AND gorilla glued AND super glued onto the frame, but they'll come loose after a bit of force. because i remember i was hanging off of a wrench that was on one of the bolts, and it didn't budge. i have no clue how my friend got that one to come loose.
