High Speed vibration, can't find what's causing it.

Yes just a spin balance
Well my race weekend got put on hold again. I took my wheels to get balanced and one wheel wanted 8 ounces to balance out. Didn't help that it was bent. Firestone must of bent it last year when they mounted my brand-new MT 295/65/15 ETStreetR tires. I didn't really want to spend over $800 for two wheels right now. So I ended up buying a complete set of jegs ssr spike wheels for the dakota.. pluse seeing how nobody is making headers for a gen3 hemi. I have been thinking hard about just biteing the bullet and building up the dart sport.
