I ended up clearing, I just installed the oem brembos yesterday, I used washers to measure the clearance I'd need for the fronts and measured at 14.3mm, bought a 15mm spacer for the front only and cleared perfectly without really much of a poke. Rears fit without modification. Running xt006r 18x9.5 +10/11 + 8
18x9.5 +10mm 5x114.3 Black Chrome XT-006R
18x11 +8mm 5x114.3 Black Chrome XT-006R
When replacing the base level brakes the Brembo package you had to add a 15mm spacer to the front only.
I am interested in the XT-206R’s primarily, I’d assume that these would fit the same as the XT-006R’s as Cosmis only offers the same exact sizes for them as well.
Lifessimple, I really liked the setup. I was wondering if you are on stock suspension, and if you had to roll/modify anything. I couldn’t find your tire specs anywhere but If I read your post correctly you have:
18x9.5 +10mm 5x114.3 Black Chrome XT-006R
18x11 +8mm 5x114.3 Black Chrome XT-006R

Hey Guys,
I was thinking of running the Cosmis xt006r 18x9.5 front and 18x11 rear what do you think is the biggest tire i can fit? I was thinking of running Toyo R888R but I heard they run big. I would love to do a 275/305 on my Z but worried with the offset of 10 and 8 it might be too aggressive for my rolled rear fenders and this tire size. Would a 265/295 make more sense or is that still too wide?

fenders rolled flat in the back of my car, 18x10.5 +10 and -2.1 camber, had like 2mm of clearance on a 285/35-18
Thanks for the info I don't want to have crazy camber in the rear just wanted as much traction as I could get.
