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.

How about the 5-lug Question and Answer Thread?

Can I us the 914-6 rotors with the existing calipers or do I need to drill 914/4 rotors?

Either/Or but, these days I recommend the 914-4 rotors machined to 5x130. This is because you need to machine 4mm off the diameter of the very expensive 914-6 rear rotor so... if you have to machine both. Use the less expensive one. Plus, it will still bolt to your drilled 914-4 hubs. The 914-6 rotor will not.

Also I am looking at a early 70's 911 SC rear setup

No such animal but, I think I get your drift. If you go with the rear calipers you won't have a handbrake. You could get the handbrake off those arms and modify that to work but, in the end, you'll be in it for about the same amount you would if you found some Ferrari 308 rear calipers.

If I get the 911 stub axles are there any modifications needed

Modifications? No. You'll just need a pair of Sway-a-Way axles in the 914 Length with the 911 28 spline count. One of my favorite combos because the axles are only $308.00 and they allow the (BIG 911) CV's to float for better torque distribution. And... no adapters to worry about etc.

Also do the 911 rear calipers bolt up or will there need to ne modifications

They will bolt up with 4.5 - 5mm spacers under the mounting ears.

911SC parts are what I recommend

Not me. Those are the heaviest calipers ever made for a 911 and they're basic "off the shelf" european sedan issue (Mercedes, BMW etc.) Our cars are some of the lightest production cars they've ever made. I wouldn't add all of the un/semi-sprung weight to a 914.

I recommend the more nimble 911T strut and the lightest caliper available which is the Brembo aluminum caliper. It has the same piston size as the SC's A-Caliper and the same pad size. It bolts to the 3" spacing and has the same 48mm pistons. Same stopping power minus 10lbs. of assembly line, garden variety caliper. I recently purchased two pairs of these struts in our classifed section for amazing prices.

On a budget or off, I would definately go with the T-Struts and the Brembos.

The rear stuff depends on if you just want to go 5-lug or, if you'll be putting some power to those CV's... read those links.
