I'm finally getting rid of the 4-to-5 lug adapters and doing a real Porsche 5 lug front suspension. Contrary to normal practice, which is normal for me, I guess, I'm installing real 914/6 struts with new Bilstein inserts. I bought the parts about 5 years ago on eBay, and the kit was all-inclusive, with freshly painted struts and new ball joints, bearings, rotors, pads, and brake hardware, and rebuilt M calipers. My excuse is I didn't know any better at the time, or I'd have looked for a later 911 set with the later bearing type, but alas, I own it now and everything is in real nice shape.
I think I'm good to go on parts and tools, but I'm trying to find out the torque requirement for the lock bolt for the ball joint. It's an M10 x 30mm x 1.5mm pitch, going into steel threads in the strut; presumably the lower part of the strut, below the tube, is forged. Looks like an M10 grade 12.9 bolt is good for 50 ft-lbs, but I don't want to chance stripping out the threads. Nor do I want the BJ to pop because it's too loose. Does anyone know the torque spec? Thanks! Picture below- PS- any tips for installing this type of strut? Thanks! |

Just finished a fit check of most parts. Everything goes together as it should, with two exceptions- The hole in the tab (on the strut) where the hard and soft brake lines meet is too small for my '76 style brake hose. These were originally 914/6 struts, and didn't the early ones mate hose-to-hose, and then connect at the caliper with a banjo bolt? The tab is the same width as my '76, so I'll just ream the hole out to fit. The tab and hole are also in the right place to connect my '76 hard line from the M caliper. Easy.
The second fit problem is the dust shields. They rub on the rotor. First I though I goofed when I specified the part number when I posted my WTB here at the site, but looking through PET, this same part number covers both solid and vented rotors. It looks like I can easily reform (bend) the shields back out of the way, but I'd appreciate any comments. The alignment of the rotor in the caliper looks perfect. See photos. Once these are cleared up, I just need to await my ball joint washers, and it goes back together. Jim Those plated dust shields and restored calipers are the work of Eric Shea. Beautiful job, Eric!! |
