I'd have to say 95% of the shaking was coming from the tires. I wasn't receving a proper high speed balance at my previous indy shop, that coupled with improper tire pressure caused them to cup.

I went to Butler Tire, there they convinced me to order the new Toyo Proxy II's..against my better judgement I did. Since then they have been properly balanced, and properly inflated as well as rotated. The car drives well, at all speeds. It also sounds better too, less tire noise. It's put trust back into the Toyo brand for me.

I hope this helps. Any questions just ask, good luck.
