Where exactly are the adjustment bolts on my '79 SC?

--------------------------------------------------------------------------------

Saturday afternoon I'm doing the front wheel bearings and while I'm at it im dropping the front a touch.

Any comments or things i should watch for on the wheel bearings "

and where are the adjustments on the front suspension? I was told directly behind the hubs? please advise, thanks!!!!

I assume--pretty vague description--that you mean the torsion-bar adjusting bolts. They are at each outer end of the transverse aluminum crossmember subframe. Yeah, they're "directly behind the hubs, but about a foot directly behind 'em.

If I plan on lowering the 911 in the front, then i think that the Torsion Bar adjusting Bolts are what i'm looking for? yes steve? I knw i sound like a ****zkauf here, but I'll know what i'm doing when i'm pointed at the right thing Have you lowered your front?

No problem, there's no such thing as a silly question. And yes, those are the bolts that adjust front-end height, but do it judiciously and take exactly the same number of turns on each side, assuming your car isn't already wonky.

The most basic way that the factory raised front-end height from what's generally called Euro-height to whatever was required by U. S. DOT bumper-height requirements was to put a big fat washer at the top of each front shock, between the shock and where it goes through the top of the fender into the strut mount. Certainly that was true of my '83, though I don't know whether or not it was true in 1979. So that's the first thing most of us do--remove the extraneous nose-raising washer.

Yes, I've lowered my front end, although by no means drastically. Can't remember what the measurement is, but there's a proper distance between the ground and the highest point of the wheel-opening arch, something like 25.5", maybe 24.5". A search should turn it up, and there's a corresponding measurement for the rear-wheel arches. You can run into tire-interference problems if you lower too much.

Lowering will throw of the alignment and balance of the car. You will be miles ahead if you consider an alignment and corner balance with the front and/or rear height adjustment.

You might want to ask any Denver people on the board or contact your local PCA club and ask for a shop that does Porsche's.....Joe Bob's alignment shop on the corner may not be the best place to go.

One full turn will drop the car about 1/4 inch. You will have to put the car on the ground and actually drive it a short ways to see exactly how much it changed. I just did this. And, yes, it will minutely change your toe-in setting and even more minutely, your camber. If you use a bump steer kit, you can cancel the toe change, but unless you have good skills and some basic equipment, then follow Mike's advice.

okay, so i guess i should look at the washer situation. Is that something i just need to look for? like pop up the trunk and look or will i only know by pulling out that shock?
Storz garage has recommended paris tire for aligning after.
