Would we need a different brake rotor? or does the stock SI rotor works well with the genesis caliper? Very interested and thank you for the infoFor it to be a full bolt on, you have to make sure the caliper bolts line up, otherwise you'll need a specific brake. The Genesis calipers indeed bolt right up. The only issue is that you'll need to find wheels that will clear the calipers (they are huge). I had to sell my two sets of wheels and has to find 2 sets that clear them. I personally do not like using spacers, that's why I sold my previous sets. Here's my 17s. Advan TC2 17x8.5 +31.
