as far as Camber alignment goes, keep in mind that correcting that will be a little more expensive than most typical cars. I have an 04 GTP and I've found out through All-Data that this particular car needs either a Camber kit which comes with eccentric bolts for the lower part of the McPherson Strut, or you can go a little cheaper by boring out the upper bolt hole on the stock lower Strut mount to an oblong shape and installing a new (OEM approved) bolt to fit. Ive went with the eccentric bolt cuz my left side had a huge amount of negative camber caused by a previous accident. but all is fixed and running fine, doesnt pull at all to either side nor wear out tires more than normal.
