I want the outright best performance spring for the Scion TC they make. As far as I know the best for performance are TRD, H&R Sport, Vogtland and Eibach Pro Sport springs... I dont know which one to get, help me figure this out! Thanks

 

Progress springs FTW!

 

your going to get alot of different opinions but i have had TRD springs for around 3 years i like them, but now that im getting wheels they arent low enough for me (only a 1.25 drop) so now im thinking about getting tein H tech or S tech. one thing to think about is are you getting shocks? the lower you drop the less your stock shocks can handle.

 

I wont be getting struts/shocks for a while! But I still dont want a really aggressive drop cuz then it plays a huge role in affecting the performance of the car in a negative way.. Ill have to check the drop on the progress springs :D. I wanted something that would make my car not look like an 18 wheeler anymore but I also wanted something that was performance based and stayed within the max drop of 1.4 to 1.6 so the performance doesnt suffer. Thanks :D
