hey but custom hats will only change the location of the rotor along the axis of rotation - if the pad sits high or low only the caliper adapter brackets will change this
i.e. the bracket must be changed to move the caliper up or down from the rotational axis (hub centre) to rectify this.
I'm guessing to see if the pad extends up higher than the rotor top? or too far down??
if it's protrudes above the top of the rotor you'll get some knock off and if it's too far down it may interfere with the hats.
i guess he wants to know if the top of the pad is flush with the top of the rotor
FYI this is completely wrong.
The if the offset is +33 then it will sit in toward the hub.
A LOWER offset pushes the wheel towards the outside, ie toward the guards.
A GTR offset is anywhere from +12 to +30.
These will sit too far inboard on a GTR.
just to throw it into the mix - even though it is the RB26 original Greddy plenum:
Garage Saurus have cut axially in the direction of the runners and inserted diversion plates along the plenum (i.e. perpendicular to flow of air into the plenum), I assume to redistribute the flow to the cylinders. Do people think this will be necessary in this instance - there must have been a difference in cylinder flow, or else why do it?
