ok so i have been lurking on the forums now for the past week searching and searching.
this is the problem i have run into i was origanaly going with the h&r springs because with the 1.4 drop i dont think i will need a camber kit. now im looking at the preogress tech springs. they are a 1.8 drop and im will be paring them with koni yellows will i need a camber kit with those springs.
also i will be getting the trd sway bar with the nst front and rear strut bars.
i was going to buy the polloyurithan bushings but i think that might be over kill.
anyways will the 1.8 drop give me any camber problems thanks.
ps
if you think i would need anything else let me know i want this car to ride on rails and my budget is decent (i put alot of importance on suspention, going around coners are better than going straight!)

You won't even need to think about a camber kit unless your drop is well over 2".

Have Tein H-techs, 1.9"F/1.5"R, and aligned no problem. Folks here have put on S-techs (2.4/1.9) and bigger drops without needing a camber kit.

By the way - why don't you just put on coilovers?

 

had problems in the past with ride comfort before, to bumpy. plus i like the fact of not guessing when it come to ride hight.
has anyone used progress springs before and how do they like them.

 

Good thinking there. And like others have said, you won't need to worry if your drop is no more than 2in.

 

I hear a lot of good things about Progress. They are a solid company that is why Scion put on their coilovers into their tC. Just so you know.....they are progressive springs meaning they won't get much lower probably 1 cm but they will be that height. No you will not need a camber kit since it isn't that severe of a drop.

 

All lowering springs will make the ride bumpier. It's because of a higher spring rate if you want a softer ride than just get custom springs and stay at that height. But when you drop......you will def sacrifice the ride quality.

 

i know its going to get alittle more bummpy. it just got to bummpy with coilovers all my cars have been lowered so i know what to expect.

 

i have tein s techs (2.4 inch drop) my alignment is exactly where i want it for autocross.
kudos on the konis thats my next step.
