nzarano Posted September 5, 2018 Share Posted September 5, 2018 has anyone ever made a backing plate that allows for ducting to directly cool the front braking system? something like this: https://www.google.com/search?q=brake+duct+backing+plates&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj73szWjqTdAhUGSN8KHWWxAPMQ_AUICygC&biw=1133&bih=666#imgrc=onOrFg9P04DUqM: any input on how to make one for the 240z would be highly appreciated! just installed new porterfield pads and good rotors and still suffering from fade on the backroads....

Neverdone Posted September 5, 2018 Share Posted September 5, 2018 (edited) That's the stock brake backing plate with a tube welded on. Edited September 5, 2018 by Neverdone Quote Link to comment Share on other sites More sharing options...
grannyknot Posted September 5, 2018 Share Posted September 5, 2018 A lot of the autoX guys simply remove the backing plate altogether, cool air covers the whole disc. Quote Link to comment Share on other sites More sharing options...

Often times ducting is needed for road racing. The higher airflow prevents heat soak and fade that you don't run into with short Auto-X runs.

Neverdone Posted September 7, 2018 Share Posted September 7, 2018 That's not mine. But you should run an airdam if you're actually going to race the car. Front end lift isn't your friend. Quote Link to comment Share on other sites More sharing options...
nzarano Posted September 7, 2018 Author Share Posted September 7, 2018 not having issues with life as much as i am with fade, lots of braking and turns on back roads not so much high speed Quote Link to comment Share on other sites More sharing options...
calZ Posted September 7, 2018 Share Posted September 7, 2018 What kind of pads are you running? If you're overheating your stock pads, you may be able to just go to a more aggressive pad and avoid the work of setting up ducts. Quote Link to comment Share on other sites More sharing options...
260DET Posted September 7, 2018 Share Posted September 7, 2018 Yeh I'd try higher temp rating pads and remove the backing plates first. Quote Link to comment Share on other sites More sharing options...
nzarano Posted September 9, 2018 Author Share Posted September 9, 2018 (edited) im running porterfeild r4-s compound all around, bled the system and it has good dot 4 in it, although i might do that again and put new bleeder valves in just to be sure Edited September 9, 2018 by nzarano Quote Link to comment Share on other sites More sharing options...
cgsheen Posted September 10, 2018 Share Posted September 10, 2018 Hmmm... I'm running Porterfields and when they heat up, they perform better. Although my Z likes the uphill better, there's this downhill run I take up above Tortilla Flat in the Superstition Mountains. By the bottom of the hill my friction is working it's best - and I've never noticed fade. I'm running vented rotors in front. Quote Link to comment Share on other sites More sharing options...
nzarano Posted September 12, 2018 Author Share Posted September 12, 2018 i have drilled and slotted rotors up front as well. im starting to suspect something else is up...? Quote Link to comment Share on other sites More sharing options...
