I had a shaking problem once with my MRS Spyder and it was out of round tires. Some of those wheel tire packages come with crap tires. I did everything possible to figure out the shake in the front end, and then I replaced the tires with Falken's and problem solved.

 

Great news. You always got to try the easy stuff first. It could have been something else, but that was an easy & quick check.
