Where do I begin? So much talk about brakes and I am nocloser to a solution. I went with the 2002tii brakes from 1972 on limited information and got burned. The posting says they are a bolt-on to the early 914's so I tried them. No good. The bolt spacing on them is almost a 1/2 inch different. Did I get the wrong year? And does someone have the dimentions from the BMW 320i rotors so I can order a custom vented hat/rotor for my 1972 914 2.0? (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Just a quick comment as this has been hashed out soo many times...
If you are upgrading the calipers and the size of the pads, you should also upgrade the rotor. Both are heat sinks, which once overheated lose their capacity to apply friction and thus stopping power. Larger pads just heat up the rotors quicker and your brake fade will come on sooner. The ability to lock up the brakes means nothing, as i bet that same system with a hot stickier tire or slick would not be able to do that. Truth is, when you lock em your ability to slow the car is decreased from that of pre-lock state. Anyway, all I am saying is go with whatever you want, just make sure you are adhering to the proper physics of the system in question. When I found that the stock system was no longer effective was in enduros of an hour or so, or abusive 30 minutes sessions where I was trying to lay down successive hot laps. There would be fade at the end of these kinds of sessions. For four lug, your first best bet is to make sure your stock system is in top shape. Once that is done, try some cooling options such as ducts in the front with hose directed at the rotors. Or, try picking up a set of 993 brake cooling channels. They are at your local dealer for about $15 each. Mount those with zip ties or other creative measures on your front arms. I have these ready to mount in just a few days from now. This will go a long way to keeping the heat down. Excess heat is the enemy of braking. Just my lowly opinion with a smattering of fact...
