changed rotors on the front of my 98 Cobra saturday.....i have 18" Bullits all the way around...and i have drove it about 5-6 miles...i got back and decided to check the lug nuts and they were somewhat loose.....so to make sure the wheel wasnt on loosely,i jacked the car up....loosened the lug nuts real good....moved the wheel around a little bit and pushed it all the way up....tightened the lug nuts while in the air....and then tightened them again when i let the car down....took her down the road 5-6 miles and i get back and seems they are a little loose again....anyone else ever have this prollem ?...if so...PLEASE let me know what ya done to fix it or cure it or what the prollem could be.....thanks guys
