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)

The struts were replaced with 86 Carrera units. The main thing is to use struts with 3.5" spacing on the ears so that you can use the newer calipers.
I went ahead and replaced the torsion tubes as well to get the wider range and availability of torsion bars, but you can still use the 914 ones - they are the same except for the splines. For calipers I went with the boxster fronts, because they offer a very large pad compared to the "S" or "M" calipers and are brand new. This requires an adapter, and the kit runs about a grand (ouch). No machining needed. You will likewise not need machinging for either of the above calipers. Do not see the point of going to M 911 calipers in front, as they are basically the same size as stock 914... The rears were a touch more complicated. I had the 4-lug hubs re-drilled and had the 5 studs pressed in. Have a competent shop do this. This allows me to use stock components all the way back to the tranny. I needed to add 2 washers to space the rear M Wide (87-89) caliper for the vented rear rotors to fit. No machining needed. In order to balance the ratio - simply buy a "T" fitting (porsche makes the part) and replace the rear slave. Most of these parts are pretty easy to source and not overly expensive. If you are racing the car, nothing beats taking your time and making sure you have the right components. Also, no need to flare if you are going with 15x6 wheels, so that is not a given. |
