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? |

Well crap.
I just realized the PO had converted the rears using a 4-lug to 5-lug spacer :-( This means if I want a vented 911SC rotor I have to change out the hub and the spacer as well as adding a spacer to the stock caliper and having the 911 rotor cut down (not to mention longer pins and caliper nut/bolts :-( I wonder how effective ducting from my Sheridan Standard Widebody would work for efficient rear brake cooling. Certainly easier and more cost effective to do that at this point. I'm bummed. |

I thought you had to change the whole assembly - trans stub, axle, cv's, etc to use a 911 hub. |
