70 911 suspension refresh - picture thread

[Chuck Moreland]

Customer had a vision for a fun fast street car. Think mild end of the Rgruppe variety. He wanted a very clean but low key early car, keeping a fairly original appearance throughout with upgraded performance. Yet still very streetable.

The customer wanted the underside to look as good as the top side. That's what we like to hear.

He asked if we could help with a couple aspects of the project, and we said of course we could. We love these types of projects.

We built and installed the suspension and external oil cooling. Other aspects of the project were arranged directly by the owner with other specialists. Paint work was done by Freddie Hernandez, and the engine by Supertec. With luck we can get those guys to add some pictures to this thread.

We received the tub after initial paint. Here are a few "before" pictures:









It is a clean tub.

More pictures to follow.

Should be an interesting project Chuck. As a fellow 70 911 owner, I will be watching with interest.

Hey, what's my car doing in these pictures?

I've been following Freddie's paint/body thread with this car on Early S. Owning an Irish Green '70T coupe myself, it makes me drool a little bit to think of how my car could look. As for the suspension refresh, I've replaced the control arm, camber plate and spring plate bushings with Elephant's rubber bushings, with trailing arm bushings in "sport" compound to follow for next season. I also have 15mm front and rear sways to install but that's another thing that will have to wait until next year.

Above are (almost) all the suspension parts ready to go on the car. A few items didn't make it into the picture. And those sway bars are not going on the car. But most all the suspension is there.

The sub-assemblies are already refurbished, assembled and ready to go on the car.

Front suspension:
- Polybronze bearings
- Low friction control arm mounts
- 21mm hollow torsion bars
- Turbo tie rods
- Basic strut brace
- Rubber replacement camber plate bushings
- Factory ball joints and hardware
- Bilstein struts inserts
- Rack spacer bump steer kit
- Front wheel bearings

Rear suspension:
- Polybronze bearings
- QuickChange Spring plates
- 27mm QuickChange torsion bars
- Weathersealed monoball cartridges
- Rear wheel bearings
- Bilstein shocks



These are the items that were powdercoated. The finish looks great and is very durable. Notably absent is the front suspension pan, which we would normally powdercoat. In this case the car did not have a pan, the customer elected to handle this himself.

The brake dust shields are plated from the factory. However we find that if they have any surface rust at all, it looks a lot better to powdercoat them. Even minor surface rust will show a coarse finish when plated, and it doesn't look good. Powdercoat is more forgiving and has a bit of fill-property to smooth out minor surface irregularities. In this case, powdercoat gets the nod.



Every single suspension fastener was either replaced or re-plated. These are the plated items, the replaced hardware is not pictured. We used our own hardware kit for the rear suspension with all new parts, and replace selected front suspension hardware.

Hardware really makes a huge difference in the finished product. Dirty old nuts and bolts stand out like a sore thumb on new parts.

Well .......i'm jealous.
Wish that pile'O parts was going on my car.

Hey Chuck..

Which kits are these.. assume you offer these? Couldn't locate on the site..

Good talking with you earlier in the year.. info was spot on & will be in touch soon for parts & service.

Sub'd...

Wow. Just wow. That car is gorgeous. So the exterior and underside are getting the full pimp treatment, any idea of the engine?

[Chuck Moreland]

Here are some of the sub-assemblies, rebuilt and ready to go on the car. Nothing real fancy here, just renewing everything with a couple modest performance upgrades.



Customer elected to keep the original boge struts. Struts have been media blasted and painted.

We find powdercoating doesn't provide the right look on strut bodies, certainly not original looking. Hence spray paint.

On the other hand, the brake shields are powdercoated. These would have been plated from the factory, but if they have even minor surface rust the plating will come out textured and won't look good. Powdercoating has a fill property that smooths out minor surface textures and looks much better on less-than-perfect brake shields.

Fresh ball joints, just stock parts for this car.



Camber plates have been media blasted and powder coated. We installed our Camber plate rubber bushing kit, sport-hardness.

Freshly re-plated cup washers on top of the camber plates, and also re-plated bolts securing the duct shields.

Bilstein inserts have been installed.



Trailing arms is media blasted and powdercoated. New wheel bearings are pressed in.



We also installed our Weathersealed Trailing Arm Monoballs.



Parking brake assembly was rebuilt using a combination of new and replated parts. The shoes are as-original. They were in good shape.

Rear brake shields are also powedercoated.

This kit hasn't made it to the website yet.

BK, the engine is the be a fairly hot 2.7

[RWebb]

Are there any items that you envision would have been better for the design criteria (fun fast street car; mild end of Rgruppe type cars) than what the customer selected?

[m1franck]

Chuck, since the customer is putting a wilder engine in this car will you be taking care of the the additional oil cooling requirements? If so, pictures of those upgrades on this vintage of a car would be great.

Thanks

[daepp]

Wow - what I wouldn't give...

[village idiot]

These kind of threads always leave me feeling ashamed for not detailing my rear suspension...........yet

[James Brown]

The car doesn't care if its dirty, just the owner... Car talk, 2009

I'm as green as that tub with envy! Subscribed and taking notes...

We did put a full cooler system in the car. It is based on the 74-89 external fender cooler setup, but has a bunch of Elephant Racing upgrades.

However, because the engine wasn't installed, we provided but did not install the 3 oil lines behind the thermostat. Yet, these are actually the most interesting parts on a 70 911 oil cooling system.

The reason these are the interesting bits is the normal factory oil lines don't work well on the 70. Here is why:

- The pupular factory crossover pipe (the one shaped like a "?") that passes beneath the transaxle interferes with the '70 clutch, doesn't work

- The inner wheel well on all pre-1972 cars does not have the channel pressed into the later cars. The channel provides a place for the oil lines, set into the face of the inner wall. It's absence means the two oil lines that come out of the thermostat and span back to the oil tank and crossover pipe have to sit on top of the inner wheel well, encroaching on tire clearance.

So we have made our own specialty lines to address these problems. I didn't take pictures of them on the floor, and they didn't get installed - so I don't have pics of them on the car. But I do have a some stock photos that will explain this, so I will post them.



Above is the full configuration going into this car. You can see how the oil lines behind the thermostat are very different from the factory setup.

item 1B is the crossover that passes over instead of under the transaxle. It therefor does not interfere with the '70 clutch. We call this a "Universal Crossover Pipe".

item 2B is the line from the oil tank to the thermostat. It arches up and over the wheel arch to avoid encroaching on the tire. The other thing it needs to do is adapt the 26mm fitting used on oil tanks up to 1971 to the 30mm size used in the rest of the oil cooling system.

item 3B is the line from the crossover to the thermostat. It simalarly arches up and over.

Together we call 2B and 3B "High Clearance oil lines"

Here are the stock pics of the parts:







The car also got our finned oil lines. But I'll be posting some pics of those installed.

Back end is buttoned up with QuickChange Spring Plates, PolyBronze bearings, torsion bars, bilstein shocks, Weathersealed monoballs, wheel bearings, rebuilt calipers and new rotors.



The other side.




Front control arms installed with PolyBronze bearings bearings and low friction mounts.



Ready for struts - and ready for lights out.

[Chuck Moreland]

External oil cooler is plummed using Finned oil lines. These are attached to the chassis using Rivnuts. This is a very slick and sturdy way to put a set of blind screw threads into the sheet metal.



Rivnut is pointed to by the blue arrow. A little hard to see the detail, they are small. This fastener anchors an M6 thread in the sheet metal without access to the back side. It's stronger than a sheet metal screw and look 10X cleaner on the installation.



Widemouth carrera style oil cooler was installed. We used Rivnuts to attach the cooler mounts too.



Front well shows detail on the oil line mounting.



Hubs are fully detailed. The AL part is media blasted and clear coated. Fresh wheel bearings are installed, and the cap was re-plated. New rotors are fitted.

great work as always there Chuck...!!

I have a q: you can answer via pm if you wish...can you please send me a pic of the riv-nut tool you use...??
I have looked at several & not been happy w/ what I have been able to find. Also, does the tool you use also do riv-studs or do you possible have a seperate tool for those...??

Thx & keep up the great work & help to the Porsche community...!!

Unbelievable Car. I go to sleep at night dreaming of a nut and bolt restoration of an Irish Green longhood. This thread is like living my dream. Kudos to the owner and Chuck's work.
