need some springs to get a 1 inch drop. any lower its going to be a pain to drive.

do i need to change my shocks too?
for sure i want to get front and rear struts. and maybe sways if i have the money. dont want to drive in tripod mode...

no.

is there a DIY thread on how to change your springs?
i have friends that are mechanics but i would like to get an idea on how it works so i can help them too.

you dont need to do a alignment if you just change out the springs right?

i think there is a DIY somewhere...try the search button...

and yes u still need alignment

With that modest of a drop, you won't need to change your shocks/struts.

You will need to get an alignment.

As for the DIY, this is the only one I can find:

just get some TRD springs its 1.25 front and back and its not that low at all if u dont have a tc you wouldnt be able to tell its a lowered car.

what a good place to get TRD springs?
the cheapest i found was like 180 to your door.

trdsparks.com would usually be one of the best. Looks like they're about $176 to my door. Should be close.

Install guide for Hotchkis Springs but the process is the same as any other spring. Just don't follow the step where they tell you to install the new bump stop.

i dont need a camber kit if i use TRD springs right since its only about 1.25' drop?

You shouldn't... no. Just be sure to get it aligned after a week or so. I say a week just in case they need to settle a little.

how much is alignment? i mean how much is it usually.
i live in the bay area milpitas/fremont area.

thanks for all your help guys.

Typically around here a 4 wheel alignment runs about $60. But it will be necessary.

thanks for the info
