If you do it yourself then its about 250 bucks for the springs.If you pay to have them done then it will be around 250 for labor.

Don't forget the $40 for 2 new air dams to have in reserve so you can put in a new one back on when you knock one off on something.

250 for labor seems pretty expensive to me...

oh, and dont forget that you'll need a front end alignment.. mine was $86 at a tire store..

200 for springs, 200 for front springs install, 109 for bolt in lower control arm relocators and 150 for an adjustable panhard bar. I didnt need a front end alignment , it sits good and doesnt wear the tires out , but maybe the 3000 miles i drive a year doesnt show up . o well. If you put springs in i think you should put in new shocks and struts too.,

I went to the local Poncho dealer for an alignment and it was only $49...$86 was a screwing. My springs (New Eibachs) ran me $200 in the classifieds so keep an eye out for deals.

you dont necessarily need lca relocation brackets, new shocks/struts/ adjustable panhard rod.... out of all those, the panhard rod is what you should consider getting first since you'll need to re-center your rear end... but i've lowered my car and havent adjusted my panhard rod yet (i'm a lazy ***). you dont need new shocks and struts, but chances are lowering your car may shorten the life of the ones you have in, and you may have a blown set sooner or later.. and lca relocation brackets are needed only if you race it often, and need to eliminate wheelhop... these are the least urgent out of them all.

Like posted above, need?...no. Good to have?...Yes

All in all, the only expense (IMO) that lowering would incur is:

1-Springs (Est $200);
2-Alignment (Est $50);
3-Adj panhard bar (Est $100).

So it's $350 by my math and assuming you do the install yourself, it's not that bad. (Click link in sig to see how to do it). That's it since you can rent a spring compressor from Auto Zone for free but for just removing the stock springs, it's not needed. They will just fall out when the A-arm gets low enough. It's also not "needed" when installing the new shorter springs anyway but it's nice to have. If you can get a semi good deal on springs, that's what you're looking at.

Maybe these are still available:

Sportline springs: https://www.thirdgen.org/classifieds...tgo?adid=50720

Lowering springs: https://www.thirdgen.org/classifieds...tgo?adid=51565

Tubular panhard rod: https://www.thirdgen.org/classifieds...tgo?adid=52186

adj panhard: https://www.thirdgen.org/classifieds...tgo?adid=51604

LCAs and panhard: https://www.thirdgen.org/classifieds...tgo?adid=50906


Good luck!

Lowering a car changes the steering geometry, your supposed to get an alignment
