well my dealer failed to properly align the car; they didn't know how
to get -2 camber on the front.

Anyone know what the part #'s are for the control arm shims and a good
location for obtaining them?

I've been told two different ways

Supposedly if you look up into the top of your shock from the wheel well, you will see a silver plate, if you rotate the plate you get a minimum of 2.5 degrees of camber and a max of 4 or so.

Then there are the shims you're talking about, they are 993 part #'s, try searching for those instead because I can't quite remember what they are but someone recently covered them here.

I wonder if they are the same as the 996 GT3 shims?

Brian S

Apparently if you search for suspension shimms (with two m's) you come up with a post listing these so you may be right about the 996 being the same. I believe the last time I was under the car most of the parts on the front are 996 #'s with the rear having 997 springs and some other different #'s

996.341.543.90 shim 1mm
996.341.543.91 shim 2mm
996.341.543.92 shim 3mm
996.341.543.93 shim 7mm

Thanks Brian, so I fired up my PET CD and looked at the front axle diagrams for both the 996 and 997 and discovered (I believe) that *unlike* the 996 the 997 does *not* have the adjustable front control arm that can be shimmed
to adjust camber!!!

Once glance comparison at the diagrams is enough to show this! - the 996
part diagram also contains the part #'s for the shimms ... so I guess the
only way to do this is to reverse the shock "hat" at the top of the strut
towers!!!

I feel cheated!

Do a search. Many people have used the 996 shims on their 997.

Larry Cable

ok will do, although it's strange that the 996 PET page 401-00 shows the 2-piece control arm and the shims and the 997 does not ...

thanks ... probably simpler to shimm than reverse the shock mounts

- i posted this info many times, the part numbers are not listed in the 997gt3 porsche parts catelog
- the 996gt3 shims are the ones you want
- i used them, they work
- approx 1mm = 1 degrees
- order a 7mm and a 3mm for each side and that will get you upto about -2.6

cheers again Paul (you come to the rescue!) ... weird how the 997 PET does not diagram the control arm as being adjustable in this regard ...

My dealers mech will love this! (not) ... but he should have told me that he
was unable to reach -2 as that is what I had requested ...

you need to get acquainted with Tony at TC Design in Milpitas...he will get your car handling the way you want...

Is this something a dealer would do? I called my dealer about doing an alignment, and they sounded dumb founded regarding shims.

I think I'm gonna go elsewhere.

Come to think of it, will other alignment shops know how to use these shims?

GT3 Chuck

I'm sure some of the racers on the east coast can chime in on an independent shop that knows how to set up GT3s (PM NJ-GT)...most, if not all, dealers do not know how to align these cars properly beyond the factory spec...we are fortunate in California to have TRG and TC Design in norcal and Steve Alarcon and GMG in socal to fine tune these cars...

I have an unused set of shims if you are interested. I rotated the struts instead. I can't use the full camber available since I like to street drive the car sometimes. I can't recall what I paid but I will give you something off.

Head mechanic at Inskip Porsche knows how to do this, also several independant tuners around here have the parts on hand. But I am in SE Mass.
