I just installed a pair of SPC camber bolts for my sedan (I'm on 225/45R17 with an offset of +43) but I am surprised to hear that it costs USD250

.
All I got was 2 pcs of 14mm bolts with a camber on the thread and I don't know what do you guys mean by a camber kit. Should there be more stuffs than just the 2 bolts? And USD250 is ridiculous.
I paid about USD100 to install the 2 bolts with computerised alignment.
