Replacing Caliper or using the original caliper with different adapter.

NOW, what I DID run into is when I install M5 calipers on the rear of the car, I found the adapter BOLTS did not clear the lower suspension arm by about 3-5 mm. SO I had to grind away about 4mm x 20mm of material from the lower suspension arm where the caliper mounts. There is plenty of meat there and i did not go so deep that I was under the bolt flange head, so no structural risk, just an observation that some of us need some additional modification.

I have a write up under mikekilpatrick that discuss this issue during install

But, in summary, THIS ADAPTER KITS ROCKS! BEST QUALITY of engineering and Tronic KNOWS HIS STUFF! VERY smart guy and I would go to him for ANY kind of metal adapter needs!

Hey Mike, do you know if the 20inch m343 m5 rims will clear the m5 caliper on a 550? Seems like a straight forward answer but i want to make sure because the lci 550 doesnt allow the m343 wheel to mount without a spacer due to the differences in a lci caliper
