So the Subaru conversion is up and running and I am planning for next season's track events. A concern of mine is the stock solid rotors ability to dissipate heat. I went digging in the archives but the information is scattered to say the least. Most was why Boxster calipers are not an upgrade. No kidding.
Now I am very familiar with the "upgrades" and real upgrades related to early 911s. I only want more heat capacity over a run session. I tracked my warmed over early 911 for years with stock M front calipers and had no issues. Proper brake technique, cooling ducts and decent pads can really provide excellent braking. I am not as familiar with the 914 system upgrades. The system has been brought up to stock quality with rebuilt calipers and for the street functions just fine. I have no issues with the braking force just the ability to stay cool. What are the options? Will cooling ducts (AJ or other) work on these cars in the same way they do on a vented 911 rotor? What pads work well? Can I stay with 4 bolt wheels? I do not really want the added expense of a 5 bolt conversion right now. Are there any "hats" that will fit over a stock 914 brake "hub"? |

not necessarily amazing on the street
the way brake pads work.... is that they are optimal in a specific temp range... street pads never reach the temperatures of a race pad so race pads never work well on the street.... portefields are fine. but every pad is designed for a different weight of car that creates a differnt temp range due to its weight..... try cool carbons. they are much more 914 friendly due to their temp ranges with a light weight car..... portefields are designed with cars over 3000pounds and up.... |
