Will I need to buy those camber bolts from the dealer, if I'm planning to install Eibach Sportline springs? I'm gonna go to my mechanic a couple of weeks after I install them so they have time to settle fully. Dont want to get there and have the mechanic tell me he cant align the car because it needs those bolts.

 

You can get -1 camber and be fine. With springs, camber bolts are not necessary. With coilovers, it depends on how much camber you want, and it's usually suggested.
