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"? |

Just read this thread on a Subaru forum talking about Floating vs. Solid caliper design. They get a little off topic (duh, it's a forum) but what I took away from it is:
- Potentially the floating caliper design has less ability to modulate near the threshold. - Potentially the floating caliper has more slop upon initial engagement due to the number of connection linkages to get force from the piston applied to the outer pad. All those little gaps and movements need to be closed before the pads even start to grip. Of course, neither of these points have much to do with the ability for the caliper to simply stop the car. That is undebateable. And the way I look at it the solid caliper should have better 'feel' all around, but if you can drive fast with a floating caliper then you've got nothing to gain by going solid. |
