I've been doing some searching...I was just about to order the Tein-S springs but I've read they have settling problems! I don't want that...so it would be great to hear what your favorite springs are or pics if possible but if not I would just like to hear what would be the best option for springs! Thanks!

 

Most people are going to say their favorite springs are the ones they have. It's just how it is. Just about anyone you get will be fine.

If you want pics... there's a whole thread of them:

get the spring rate that are supported by the correct shock rebound rate and don't drop the car more than about 1.5-1.75" due to being severly detrimental to the car's handling.

in other words, that rules out s-techs on any shocks, goldline, slammed coilovers, etc and leaves TRD&Koni shocks, and almost every other spring out there, my recommendation is H&R sport on koni's, TRD combo, hotchkis on koni's, or any coilover out there sans megan and WR due to their spring rates and shock rebound.

again, this is all based on my opinion and experience looking under people's TC's at their suspension, and if you need to confirm something yourself, look under your car at your a-arms (the suspension arms going to the wheels) and at full suspension compression they shouldn't travel much farther than flat horizontally. as in...
