I am going to buy the tein dress up master springs, and I was wondering if I would need an alignment after I install them. TIA

Just get a front end alignment and you should be good.

anytime you mess around with your suspension & tires you should get an alignment, you dont necessarily have to but it is a good idea, when you change out springs - you should, when you get new tires mounted on your wheels you should but you dont have to, some people i know get alignments done every 30k miles only because of the streets they're driving on sucks w/ nasty potholes & crap. But its up to you if you want the alignment done now or later

its recommended to at least get the allignment checked. The allignment doesnt change much (if at all) on these cars, but a $40 allignment is cheaper than new front tires in a few months.
