Guest Anonymous Posted March 7, 2002 Share Posted March 7, 2002 Hey guys, it seems the only good way to properly add cool air to my front brakes is by routing a hose through the unibody, in the strut tower area just above the frame rail. Since I don't have any added structual support there, is it a good idea to cut a 2.5--3" hole in the strut tower? BTW, I'm thinking about a vented disc upgrade et al, would a caliper "scoop" be enough? Thanks for yur advice. Jon Quote Link to comment Share on other sites More sharing options...
QWKDTSN Posted March 7, 2002 Share Posted March 7, 2002 You've got a front air dam, just hook up a hose to the vents in it (which are actually meant to be brake ducts) and there you go... Quote Link to comment Share on other sites More sharing options...
260DET Posted March 7, 2002 Share Posted March 7, 2002 Not a good idea to cut a hole in the strut tower IMHO. I've run my 75mm (3") ducting outside the inner guard, fairly high up so the tyre doesn't hit it on full lock. Quote Link to comment Share on other sites More sharing options...
johnc Posted March 7, 2002 Share Posted March 7, 2002 Don't cut a hole in the structure near the strut tower! As stated above, run a 3" duct from whatever air dam opening you have along the lower the inside of the fenderwell. Then route it forward of the strut to a can that surrounds the solid rotor. You need to get air to both sides of the solid rotor or it will warp. If you run a vented rotor, run the air to the center hub area. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 7, 2002 Share Posted March 7, 2002 Thanks for the link. I've been looking for a good source for silicone hose, though they appear more expensive than Racer Parts Warehouse or Pegasus. Thanks again... Quote Link to comment Share on other sites More sharing options...
Guest jcp240z Posted March 8, 2002 Share Posted March 8, 2002 Does anyone supply backing plates with the duct fittings for Z's? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 8, 2002 Share Posted March 8, 2002 Try portcityracing.com. I doubt they have anything specific for the Z, but they may have something that you could adapt. Tim Quote Link to comment Share on other sites More sharing options...

Guest greimann Posted March 8, 2002 Share Posted March 8, 2002 When you do decide where to run the ducting, consider using a proper hose for the job. One source I like to use is industrial supply catalogs like McMaster-Carr, Grainger and MSC. Much better source of fittings and hose than Home Depot. For the ducting check out this source at McMaster-Carr: http://www.mcmaster.com/catalog/108/html/0170.html Quote Link to comment Share on other sites More sharing options...

John, could you elaborate on what you mean by a "can" to surround the rotor? I understand the need to somehow deflect air to both sides of a solid rotor, just having a hard time picturing it in my head - know of any web links that may show this? BTW, I have plenty of "Bud" cans - will they work? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 13, 2002 Share Posted March 13, 2002 I think that this may be what John is refering to: These can be found at Port City Racing Tim Quote Link to comment Share on other sites More sharing options...
johnc Posted March 13, 2002 Share Posted March 13, 2002 What Tim posted above... Since the stock front rotors are solid, you need to air to both faces and the only easy way to do it is to build a structure that surrounds the rotor and moves some air from the inside face (where the hose connects), over the outer diameter of the rotor to the outside face.

DCZ Posted March 14, 2002 Share Posted March 14, 2002 Thanks for the info. Those look great. If I made my own out of Bud cans, would that make Anheiser Busch my sponsor? Quote Link to comment Share on other sites More sharing options...
