so im trying to get my z in tip top shape. she gets a little shaky around 40 to 50 something miles per hour. with that being said i took it to a local tire shop so i can have the alignment done. after it was there for a short time they called me to inform me that i needed more than just a front alignment . he said i had negative camber on both sides (previous owner had car lowered before??could that be a reason for it being negative?or possibly 20 years of camber wear?) and that my particular vehicle calls for 4 wheel alignment on top of a camber kit for the front. he wants to charge me $271.45 to install the kit and do the alignment. what i want to know is if this seems right. i google search front camber kits for a 300zx and most are under $100. also keep in mind that the tire shop i go to in my town is having a $49 special on alignment. any insight is always appreciated. thankz
