NOTE!!!!DO NOT USE STAINLESS NUTS AND BOLTS ON SUSPENTION, AND LOAD BEARING PARTS AS THIS COULD BE DANGEROUS!! . When using stainless you have to be carful where you use them as they dont have the tensile strenght of the original ht bolts used. Be very cautious of what you are replacing them with. What i would suggest is to strip down all the bits from underneath the car and take down a selection of bolts you want to replace to your local fasteners and get the corect type of nuts and bolts for the job. You will find most of the important bolts will have 8.8 or 10.5 on the head (This denotes the tensile strenght of the bolt in NM). some if not alot of the nuts and bolts can be replaced in stainless but you have to be aware that some you deffo cannot for safey
