Just to square up the facts:
My bolts are the same diameter as factory. They use a D shape rather than the slot/tang that the factory uses to rotate the washer. They do use a 18mm wrench instead of the oem's 14 or 17mm wrench.
They are not "crash bolts". Crash bolts are a smaller diameter bolt shaft that allows for more adjustment than factory adjusters. Sometimes providing adjustment where there was none from the factroy
My bolts do NOT increase camber. The limiting factor, on any of the adjustments, is the slot in the subframe. Not the bolt or the washer. They make it easier to get max adjustment. this is because they provide more "lift" than the oem ones. Mine actually bottom out the bolt in the slot. Which the factory ones do not. But you can do this with a prybar and the oem washers.
If your car had a max of 2.7* camber with oem bolts, you will get a max of 2.7* with my bolts. they are just a better quality design than the oem ones.
I hope this ends the debate.
