So I know this has been talked to death thousands of times and when I do a google search there's reems of information, but rather than spend the entire evening reading through many posts that really aren't relevant, I thought I would pose the question and see what turns up.
Recently I had a four wheel alignment and corner balance done by a really great and well known shop out my way (who are very familiar with track cars for my local track-Summit Point) and when I asked the primary mechanic today what things he might suggest for my sbc Sheridan standard wide-body conversion, he said upgrading my rear brakes would be pretty important for that track. Soooo, yes there are lots of ways to go to be sure but I was wondering about retaining the standard rear 914 brake (and e-brake) but using the vented 911 SC rotor? Do I recall Eric made/makes a spacer for this or is/was that for converting 914 fronts to rears? A lil confused this particular application. I like the idea of retaining the stock 914 rear calipers if I can but I really want to go to vented rotor (as opposed to drilled). Thoughts? |

I added spaced 914 rear calipers and 911 rear vented rotors cut down by Eric Shea. My progress thread has some info and pics on my upgrade.
You need a spacer between the rotor and the hub to properly space the rotor in the caliper. One thing I ran into with the spacer is when the spacer is placed between the rotor and the hub, the rotor loses it's centering capability on the hub. In this case the little screw that holds the rotor is important to setting the rotor in the center of the hub. Also the 911 rear rotor screw placement is not in the same place as the 914 hub. I had to drill and tap a new hole in the hub. Spoke's Progress Thread |
