Struts/steering/brakes update, What to change? Options

[mtndawg]

I have a ‘73 6 conversion 2.7l and a previous owner put on bmw brakes with stock 4 lug wheels. The car drives fine but I want to put on 5 lug Fuchs, which I have. I also have 911 struts with calipers that need to be refinished. I’ll get pmb involved for this. The calipers are not the fancy light weight version. Here’s my question…would it be worth the effort and $ to locate a full steering rack instead of just using the struts I have? Should I consider buying the lighter calipers rather than getting my current 911 calipers refinished? Would love to hear from people that have done this… Note: I’m just driving, not racing. The 5 lug Fuchs don’t fit over the bmw caliper.

The 911 and 914 steering racks are interchangeable for your proposed purposes here. There may be very minor differences in things like lock-to-lock turns or the stock length of the steering shaft attached to the rack (if the wrong length, use your 914 shaft). However, the steering racks make zero difference for the change from 4 lug to 5 lug wheels. 930 "turbo" tie rods are a nice upgrade though with no concern for running with either a 911 or 914 rack. You can run 911 or 914 racks with either the 914 or 911 struts.

As for the 911 S calipers. We are running aftermarket 911 S calipers and they are great. Less weight bigger pads, vented rotors. We also have PMB restored "real" 911 S calipers and PMB restored A calipers, which would be nice choices as well and we are planning to use them on future projects. So, yes consider them, but nit a necessity. Don't know what size wheels you plan to use, but make sure the wheels will work with your proposed calipers.

If you decide to go with 911 control arms, understand you will need to run 911 torsion bars (different spline count) which are thicker and stiffer than stock 914 ones. If you run the 911 control arms, you can easily add the 911 front anti-sway bar which would affect handling (unless you already have a 914 fron bar, which you could keep if you weld on the proper mounts to the 911 control arms).
