I am running an aggressive street set up with 2.5 deg rear camber and 1.5 in front, no rub issues.

Suggestion
Did you check the spacers to see if they are flat and round?

Satan had taken over.Returned to the house unmounted the fronts; test hop #2, no shimmy, but percieved some from the rear; maybe not, but at this point I was paranoid.

Home now and remounted the fronts and went for test hop #3; Shimmy at 20 mph.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I bought wheel spacers; 5mm front and 10mm rear, 53mm bolts. I got home and mounted them and went for a spin. At 25 mph the steering started to shimmy, and got worse with speed, at 45 mph it was like a washing machine with all the towels on one side on spin. Satan had taken over.Returned to the house unmounted the fronts; test hop #2, no shimmy, but percieved some from the rear; maybe not, but at this point I was paranoid. Went to the tire store and had all 4 balanced. On the drive home car was smooth or was it, thought I could vaguely feel some hop from the rears. Home now and remounted the fronts and went for test hop #3; Shimmy at 20 mph. WTF !!! An exorcism is in progress as I type, the car is in the garage being bathed in incense with Ravvi Shenkar on the stereo.
-Tire pressure is what I normally run 34/f , 38/r
-Tires are SO2, 3500 mi
-Spacers purchased from a very reputable P-Car only race prep shop, made for Fikse wheels and is what they use on P-Cars that require them.
-Tourque at 93 ft/lb
Would the Porsche/ H&R spacers done the same thing? Are my wheels bent?
Any thoughts?
Are the spacers hub centric with very tight tolerances and (for the rears), do they provide a new hub-centric flange to mount the wheels? I have found that my aftermarket wheels are very sensitive to not being hub-centric since the hubs do not have as tight of tolerances as OE wheels. Sometimes unmounting/remounting makes a difference. I'm envisioning possibly the same thing especially with the really long-bolted 10mm spacers.
The spacers are hub centric. I have Weld wheels on my Ford Truck and the lug nuts have flat washers. The bolts for the posche are acorn style and the wheels are supposed to hb centric. I have remounted enough times to qualify for a pit crew memeber.
I come on bended knee to tell the board of my failure to rember the addition of a 6mm spacer at the track to aid in clearing up a little push. It looks just like the rotor and is attached with screws. I was absent during the install as the cure to my understeer was not revealed to me until after a couple of laps. Extra spacer removed and car is seizure free.
Can I get some help on what wheel spacers I can use? I have an '02 C4 Cab with sport suspension. 18" Carrera rims with 225/285 front/rear tires. I hear some say they have problems with tires rubbing. Also, is same spacers on front and rear recommended.
I think Porsche says only 6mm in front and 15mm in rear. I have H&R coilovers , my rear measures 24.5". I am running an aggressive street set up with 2.5 deg rear camber and 1.5 in front, no rub issues. My spacers are 6mm front, 10mm rear. If I went to 15mm in the rear I would need to roll the fenders. I am curious as to the mounting style for others; mine slip over the hub sandwiched between the wheel and rotor. This (rears) does not really allow for the wheel to center on the hub. I had to mount the rears loose and rotate to get a good center mount measuring with a feeler gauge. I would like a more positive way to center the rears. Thoughts?
