today I spend most of the day trialling the callipers (rear) to modify the dust shields, I wanted to do this before I paint the callipers so I don't risk scratching them during the mockup and proceed to cut the shields to accommodate the Porsche callipers.
I am using rally road brackets
So the first step was of course to remove the wheel, calliper, and rotor, nothing out of this world here; I also was very lucky and my rotor screws came out pretty easily
Below you can see the share I followed for the upper part of the dust shield. at this point, I had cut just enough to bolt the upper section.
Next, the lower part, I did this to avoid cutting too much and follow the pattern of the mounted calliper, as you can see it was not much what needed to be cut just to seat the bracket, but you do need to cut off some more for the calliper to clear.
After cutting the shield I was able to mount the calliper
So far so good, but then I also checked how centred was the calliper in relationship to the rotor, and I found that is 3.2mm too car inboard. the bracket kit comes with 4 washers but they are just 0.8mm thick, so for the calliper to be centered I would need to use the 4 washers on one calliper, so I need to get some stainless washers from home depot.
See how the supporting pin of the outboard pad is contacting the rotor
Here you can see how much clearance is on the inboard side (that gap is 3.2 - 3.3mm), I measured it with feeler gauges. in this very picture, you can see where the bracket seats to the knuckle, there it is where the washers need to be placed, ideally 1.6mm thick to put it in the middle.
I will post a photo of the other side so you see the final product of the cut, I did use my Dremel smooth out the cuts and since I don't drive on the rain or winter I am skipping paining it for now as I would hate if I spray other bits in the process, plus you don't see it at all. bellow
