I looked at that thread and had a thought...why not put the calliper on the inside of the hub instead of the outside like stock? you could shave a mm on the hub and maybe the caliper and get the 8mm difference there and thatwat you wouldnt have to space out the wheels...
hmm the question i quess is do the discs rub if bolted right on?
I had that same thought myself mate; it won't work unless you want to do ALOT of custom fabrication. The ideal position for the levin calipers is flush with the mounting bracket; in other words, the hub will sit under the bracket for the caliper, then you need to make up a bracket to put behind the hub and caliper to keep the caliper in place and shave a few mil off the hub and caliper bracket to stop the caliper rubbing the inside of your wheels (unless you have 17s).
I planned out every conceivable option before doing the swap; sure with enough time, effort and skill it could be done better though... I just lacked the metal fabrication skill to attempt any other option and trust it
Oh and it won't go on the inside as the bolts will only attach one way; the disks wont fit and you won't be able to tighten the mounting bolts unless you use the stock position or custom make brackets to suit
