I'm a little perplexed about a low speed (~40mph) shimmy just developed on my street wheels/tires. Perhaps someone has an idea as to the source.
Here's my situation. I recently took off my Volk 18/19 wheels with mounted Toyo tires to run OEM wheels and tires for the Willow Springs track even on March 23. Prior to this day, my car ran smooth with no steering wheel shimmy at all. I had the OEM wheels balanced before running them on the track. I experienced no incidents of any kind and, in fact, was quite impressed with the handling and grip of the 15/16 OEM set-up with new Dunlap Sport 5000 tires.
When I remounted my Volk wheels to drive home from the track, I noticed the low speed shimmy. The shimmy goes away at speeds below and above about 40mph. When I got home, I checked the lugs for tightness and only needed to perform a very slight tightening of some lugs of no more than an 1/8 of a turn. The shimmy is still present.
Does anyone have any idea of what could cause a shimmy on balanced wheels/tires by simply remounting them?
