dust shield modification for brake ducts

[supraguru05]

I am working on installing brake ducts and just want to make sure before i cut that what i am doing is ok. i need the shield to be removable so im simply going to cut out the area between two of the bolts so that the shield isnt a full ring. the issue is this cut exposes the hub directly to the back of the hub flange and potentially brake dust and heat. just wanting some opinions. here is a picture showing where i will be cutting it.

what about cutting it into sections, so you have a 2 peice removable shield?

if i split it without sections of overlap im worried about it flapping and touching the rotor, although i might be able to trim it to where there are sections of overlap to prevent it from flapping around.

why not just cut some holes in the shield.

then add a stiffening bracket. weld it on, or even 5 min epoxy would be strong enough.

get creative, this isn't rocket science.

Note what was done on the brake dust shield and the ducting installation - http://www.robrobinette.com/S2000BrakeDucts.htm

Installation the bracket on the forward portion of the shield, NOT on the rear

would that s2k example really cool that much? after seeing the vents on cars like the corvette i wouldnt think that would do much, the vettes dont even have much of a shield. wouldnt removing the shields or opening up the inside of the rotor and channeling airflow to the entire rotor/caliper assembly with airflow guided from the bumper be more effective?

doesnt seem like it would make a difference at all. just upgraded to a bbk.

maybe i should clarify, i was trying to make removing the shield possible so i could pull it off and weld on it so i can run my brake hose form the bumper to the inside of the rotor. ive decided that its not going to hurt anything to cut that section out so i already did it.

That S2k is a great example Howard, in fact that's one of my previous instructors' car. I think it's an effective way to add more cooling.

I don't think it'll hurt anything guru but I was going to try to do like on the s2k site and use a 2.5 flange placed into the shield to give the hose somewhere to mount. Of course the closer to the inside of the rotor, the better since they're designed to pull air from the center out. You want to guide air through the rotor, not just to the area. The stock dust shields had a small vent but it was near the face of the rotor.
