Hi, would love some recommendations regarding upgrading my brakes w/o braking the bank so to speak.
I recently upgraded to a 911 master brake pump or is it know as a cylinder and stainless steel brake lines. Changes my brake fluid reservoir to a new OEM Porsche one so the front trunks looks nice and new. So before I go rebuilding and making my current calipers all nice and shiny, what other options do I have to improve my braking performance? Can I go 911 brake calipers w/o having to change my whole front suspension to 911 suspension? I appreciate everyone's advice. I will post pictures soon, my car has been a two year journey and quite a story to get her where she is today. Many ups and downs, and almost 100% restored, bigger bored 2.0 now 2.4, new interior, paint, konis, springs, stereo, the works... Originally 52,000 now 55,000 mile original car. 75 2.0 now with back dated bumpers and many other items, so I call it Zambezi green , although a 75 was known as Forrest green. Finally proud to drive her around town. Been a hobby, passion, obsession and many reasons for past arguments regarding my income investments. Thanks for your recommendations.

However, Greg just (indirectly) pointed out the major shortcoming in my statement. I said "in that application". Greg mentions Laguna, which is notoriously hard on brakes. As in, puts a lot of heat into them, without a whole lot of cooling time available.
When you are putting a whole lot of heat into the brakes, and they don't have much chance to cool down, larger brakes can help. Physically larger rotors give you more heat sink, plus more area to radiate heat away. Ventilated brakes run air through the middle, carrying heat away faster. Larger calipers have more mass and more fluid, meaning more heat sink again. But about the only people who use their brakes in that sort of fashion are doing it on the Big Track. --DD |

In heavy track usage, stock brakes will overheat, fade, and then you will not be able to lock them (at least not with out excessive pedal effort). Maybe some elaboration/clarification is useful to apply it to certain real world situations but your statement is pretty much axiomatic. |
