You have to widen the hole to get to the adjustment screws while they're on the car. You could install, eyeball it, uninstall, adjust, reinstall until you get it right....but for that amount of work, just widen the hole.
other notes...I installed the BC's on a non-speed3 with factory wheels/tires
front - the tab for upper end of the endlink is attached more towards the center of the strut, putting the bracket with the ABS wire REALLY close to the rim. Aftermarket rims with different widths/offsets could be affected by this. I put the bracket on the other side of the tab for more clearance/peace of mind. I'm in the 0-1 degree negative range with a 1 finger gap and the camber adjusted fully towards zero degrees. You should be able to get pretty wacky with the negative camber up front.
rear - I had to remove one of the height adjustment rings to drop the rear to match the front.
Overall, I'm happy with them.
