325/50/15 clearance problem???

[spotman]

I have been running the 325/50/15 MT drag radials this season at the track. I have been hooking good with them but I just took them off and realized that I have been rubbing the inside of the fenderwell. I did have to remove the upper quad shock to make them fit. I have bbk upper and lower non adj control arms and drag launch springs front and rear. I believe that it is only rubbing during launch and shift because of my suspension being so soft and squatting. If I change to adj upper control arms and raise the back end up a little so it will stiffen up do any of y'all think this may fix my problem? Thank you for any input.
