Very nice looking work!

Make sure the O-rings are brake fluid proof. (IMG:style_emoticons/default/idea.gif)

Making slow progress on the front rebuild.

Rebuild kit for calipers did not come with the little O-Rings that seal the 2 halves.

My local hardware store has lots of miscellaneous O-rings so hopefully I can find something that works.

We have a line of viton O rings we make under contract for another company we have the ability sell them as it's another industry. Let me know what you need.

Thanks @mikey914 text with specs sent

Can someone educate me on the "brake piston gauge plates"?

I took a 50/50 guess as to the orientation....is there a correct up and down or I guess should it be right or left? The piston could rotate 180 and go either way...?? (I'm sure if there is a wrong way that's what I did!)

If doing both calipers at the same time be sure to check orientation before bolting halfs together.

New discs and bearings are in!
Followed Ian's video for good measure.Attached Image

New Bilsteins, tie rod ends, ball joints, bushings, brake master cylinder, stainless lines, pads and lovely calipers will be on next once I get the o rings from 914rubber

So close to getting back on the road! Can't wait to feel the difference!

This car is like the most frustrating game of Whack a Mole! Fix one problem and boom there's another. (IMG:style_emoticons/default/hissyfit.gif) (IMG:style_emoticons/default/hissyfit.gif) (IMG:style_emoticons/default/hissyfit.gif) (IMG:style_emoticons/default/hissyfit.gif)

So, suspension, brakes, everything is in rebuilt and pretty! Today's project was to set the front ride height. I followed the procedure, Floor to Center Hub - 90 and that's the height to the center of the torsion bar. A pain in the ass going in circles but I think I finally got it pretty dialed in.

The issue is: now the front is raised up to the correct height the tire strikes the front valance when I turn the wheel hardly at all. I couldn't get the car out of the driveway.

I did not have the issue pre-rebuild, however, pre-rebuild the car was slammed with tons of camber.

My guess is, like the many issues these have brought me, it's the wheel/tire combo.
Rivieras with 195-60R15. I think they are just too damn wide and too tall. The PO messed with so much stuff on this car to make these stupid tires fit.

What do you guys think? Am I missing anything else??

I can't afford wheels and tires after all the cash that went into this so far so i'm limited to just tires.

with 195x60 tires, it should not be that close to the front fender lip/valance. Any picture of the whole tire seeing the whole fender distance? or pic of the rear side of that tire to the fender?

below is 205x60 tire on 15x6 fuch wheel.

It’s the Rivs. That’s a wide tire for them but fine if you have Fuchs.

It shouldn’t be too tall. I have 195x65x15 and it fits fine. Is it a stock valance or aftermarket fiberglass?

I'm thinking that Rivieras must have less backspacing than most other wheel options.


These are 195 65 15s on reproduction 5.5" Fuchs...

No rubbing ever. Not even close.

Here is a side view pic. The ride height is too high and the back of the car is on jack stands making it look even worse, however, I don't think this is my issue. I believe it is the stock valance.

I'm also now thinking the formula for front ride height is not working with the rivieras...ugh

Have you settled the suspension? You need to roll or preferably drive it a bit. By formula, do you mean the Haynes manual?

I was able to drive back and forth in driveway getting on brakes etc.

And I followed the formula from the old porsche manual....

The type of wheel won’t make a difference. They just hold the tire in place. You need to go down at least one notch on the torsion bar splines, maybe/probably two.

It looks like it is way to high.

maybe too much negative caster or something wrong with the suspension that makes the center wheel towards the front since the picture show there is a lot of space at the rear side.

and the lower valance seems bent that makes it leaning inside or that was cause by the tire rubbing to the valance?

I agree with both: too much caster and the lower valance looks off.
