I’m looking to take my car to my mechanic he’s willing to do it but I need to source all the parts and he’s going to charge me if I’m missing a part
Can someone please tell me what exactly I need or if this is it and if I’m on the right track I’ve ordered all these things already/have

These are 19’ wheels
The brakes are 18z porsche 6 piston
brembos with 345m ml55 amg rotors
I’m sure somebody has these exact same wheels and has done a big brake kit just wondering if they needed spacers or if they were fine without them
