What that did for me was allow me to go with a bigger rotor. The closest fit i found was from an 06 lexus GS350 front rotor. I had to machine the hub centric out to our size and machine a little out of the hat to clear our hub diameter.
Your going to upgrade your rears as well aren't you?
thanx for the info. the reason i wanted to stick with 1g calipers is the website said the brackets are design for a 1g caliper only to be able to use the 13 inch cobra rotors.
if i go with 2g calipers will it still work with cobra rotors?
i do plan on doing the back also with 3kgt rear or evo brakes.
so i just talk to the guy and he says the caliper measures from outer side of mounting ear to other side about 4.25 inches... and from what i know the 2g is like 5 inches plus.
anyone have any inside on this?
