is there any difference with the drilled to slotted... in the 4000 series there.
cuase im really liking the cross drilled gold 4000 series.

is it mainly that u cant use it for motor sport
somone told me they can also have a chance of cracking the drilled ones ??

the other question i had was does the 4000 series keep the same dimentions.
width and where caliper sits etc
