hey my name is shea....im from the Houston, TX area....i own a 2008 Black Silverado 5.3L that ive had for about 6 months....Ill be looking to make some basic mods to it(intake, exhaust, HIDs, chip, etc.) so any recommendations would be greatly appreciated!!!

I recently put some aftermarket 22s on and they drive and look great but whenever i hit the brakes the truck shudders pretty bad...i cant seem to figure out whats causing it, brakes? rims? suspension? if anyone has had this problem or has some suggestions as to what the cause could be i would sincerely appreciate all the help i could get....thanks!
