So iv brought a full bolt in cage (made by sassa) it comes with spreader plates that need to be cut down (120mm squared if im correct) my plan was to put a plate inside and outside the car but iv read on a different forum that its not needed...my general thought is more strength the better or am i going OTT? Car is only used as a daily with the odd trackday in mind not competing, just want to do the job right. Plates will be welded in in the future.
