5 lug conversion questions, Rear pieces Options

[914coop]

Starting my 5 lug conversion.

Have drilled 914/4 hubs and was wondering about the rotors. Can I us the 914-6 rotors with the existing calipers or do I need to drill 914/4 rotors?

Also I am looking at a early 70's 911 SC rear setup, Hubs, rotors and Calipers, also has the control arms and shocks but I am pretty sire I can not use them. Know I need the 911 or 914-6 stub axles, If I get the 911 stub axles are there any modifications needed? Also do the 911 rear calipers bolt up or will there need to ne modifications I know I loose the emergency brake what are the options there.

One front question.

What is the benefit to using a 911 front suspension over a 914 front with drilled front rotors?


Thanks for your help and advice.

Granted there are many threads on this topic. I have no direct links handy. A search should find a wealth of information.

Here is a "cliffs notes" version:

Rear: If you drill 914-4 hubs, you can keep your current CV joints and this is the least expensive route. If you want 911 hubs in the rear, you need 914-6 stub axles to mate with 914 CV joints. If you use 911 stub axles, you will need to figure out CV joints and how they will fit on the drive shafts. Can be done, many threads on it and many different ways to go.

Front: The advantages of 911 front end start with the calipers. Larger calipers are available for the vented rotors. 911SC parts are what I recommend. The rotors, pads, bearings, etc are all available at any car parts store and are less expensive than the 914-4 counterparts. The drawback is weight. This setup will weigh more than the stock setup. Another advantage is that you will be using parts you don't need to modify each time you change rotors.



On a budget, I would recommend a 911 SC front end, and find the parts you want for the rear. I went with 911 hubs and stubs to get larger CV joints. I had to make custom axle shafts and source transmission output flanges to use stock 911 CV joints (still available new).


I do have a pair of real 914-6 stub axles, that I would trade for a 914-6 oil tank....


Just my $0.02

Good luck with your project.
