My car has i widebody kit on it, and underneath it there are still the stock fenders, i need to cut them out so i can adjust the camber on my wheels, because the offset is to large, how could i do this with the widebody still on the car?

I was told when i cut the 1/4 panels, i would have to tac weld them so they stay together, are there any shops willing to do this, while the overfender is still attached to the car?

i hope this makes sense, if it doesnt, feel free to correct me, or delete the post as needed.

thanks,
derek
