Hey guys, I have a question about how to adjust my rear camber in my 03' accord euro.

I am looking as getting the buddlyclub n+ coilovers to have about 10mm gap between guard and tyre(running 18's). The guy at the workshop said that I won't need a rear camber kit, he can just use 'camber bolts'.

Is this correct? Or is he going to say after the install that a camber kit in necessary, thus shafting more money out of me?
