If you get as annoyed with BMW wheel bolts as i do and you want an easier, faster way to change over your wheels then you need a stud kit! This eliminates the standard bolts and has a stud which screws into the hub itself and will not come loose (you will have to use locktite for installation).
We use these on all of our BMW 325i race cars and they save alot of time and hassle!!
Kit includes 20x 57mm x 1.5mm Pitch studs to suit vehicles running alloy wheels (can do shorter but these suit cars that run spacers).
